The results are obtained as follows： （1） inhabitants of the TGRA of Chongqing are concentrated in the area with moderate h.igh HSES, which is 78% of the total population distributed in 48% of the study area; （2） the HSES is closely related to the terrain, and it forms an arc-banded spatial succession pattern： relatively low in the northeast and the southeast while comparatively high in the west and the south; （3） large numbers of people are distributed in the area with low suitability （with higher population density than the average of the western China）, but economic development level in these areas is quite low. Moreover, these areas are ecological sensitive and fragile, many kinds of eco-environmental problems have been caused by human activities. Therefore, population migration and layout are reasonable options for the development of these areas.展开更多

By using GIS spatial analysis technology, such as spatial overlay analysis, buffer analysis and density analysis, the environmental suitability of the human set- tlement spatial situation and spatial pattern are established to analyze their spatial distribution The results show that the index of suitability for human settlements in the Shiyang River Basin is between 17.13 and 84.32. In general, suitability for human settlements decreases from the southwest to the northeast. Seen from an area pattern, the suitable region is mainly distributed in the Minqin oasis, Wuwei oasis and Changning basin, which are about 1080.01 km2 and account for 2.59% of the total area. Rather and comparatively suitable region is mainly distributed around the counties of Gulang, Yongchang and north of Tianzhu, which is about 1100.30 km2. The common suitable region is mainly distributed outside the counties of Yongchang, Jinchuan and most parts of Minqin County, which are about 23328.04 km2, accounting for 56.08% of the total area. The unsuitable region is mainly distributed upstream and to the north of the river, which is about 9937.60 km2, accounting for 23.89% of the total area. Meanwhile, the least suitable region is distributed around the Qilian Mountains, which are covered by snow and cold desert and lie in the intersecting area between the Tengger Desert and Badain Jaran Desert. The total area is about 6154.05 km2, accounting for 14.79% of the total area. Suitable regions for human habitation are mainly distributed around rivers in the form of ribbons and batches, while others are scattered. The distribution pattern is iden- tical to the residential spatial pattern. In addition, the relationships between HEI and other factors have been analyzed. There is a clear logarithmic correlation between the residential environment and population, that is, the correlation coefficient between the evaluation valueand population density reaches 0.851. There is also a positive correlation between the residential environment and economy, which reaches an evaluation value of 0.845 between the residential environment and GDP. Results also show that the environment is out of bearing with the existing population in Shiyang River Basin. Spatial distribution of population is pro- foundly affected by severe environmental problems, such as the expanded deserts, the hilly terrain and the changing climate. Surface water shortage and slow economic growth are bot- tlenecks for suitable human settlement in the Shiyang River Basin. Combining these prob- lems with planning for construction of new country and the exploitation of local land, some residential areas should be relocated to improve the residential environment.展开更多

Then the concept and characterization methods of the regional human settlement carrying capacity were proposed by means of population scale. Furthermore, a model of carrying capacity-pressure-state-response(CPSR) on regional human settlement system was established by referencing pressure-state-response(PSR) model, and the Catastrophe Theory was introduced to determine the corresponding standards of multi-criteria programming and evaluation. Taking Dalian City, Liaoning Province, China as an example, an empirical analysis on evaluation of human settlement system from 2000 to 2012 was carried out. The results showed that the carrying capacity of human settlement system in Dalian was fluctuating between 9.6 × 106 to 10 × 106 persons with a quantitative stage of the dynamic regulation. During the research period the load index of human settlement system in Dalian dropped from 0.96 to 0.84 with a lower pressure of human settlement system than the national average level. And the emergency response grades of human settlement system in Dalian were kept in grade Ⅱ(orange warning) or grade Ⅲ(yellow warning). Human settlement system of Dalian was in slight security state as a whole, but the load had a tendency of increase in recent years. The related departments should pay close attention to regional human settlement system and take active measures to improve human settlement by both intensity control and total quantity control. By comparison, analysis and discussion, it was considered that the results were basically accordded with the current situations of human settlement in Dalian, and the evaluation results were more reliable, visualized and easily applied in practice. Therefore, the above-mentioned concepts, characterization and evaluation methods of the regional human settlement system and carrying capacity could provide a new thought and method for quantitative evaluation of human settlement.展开更多

According to the comprehensive scores of various administrative villages calculated by means of multi-index comprehensive evaluation method and fuzzy comprehensive evaluation method,the human settlements of 521 administrative villages in Licheng District were divided into four types： excellent,good,average,and poor. Moreover,the spatial differences in the evaluation results of rural human settlements were analyzed using GIS spatial analysis technology. Finally,based on the evaluation results of rural human settlements in Licheng District,some measures to improve and control rural human settlements in different types of villages at various development stages were proposed to fully improve the quality of rural human settlements.展开更多

Despite this challenging context, short-term considerations continue to guide their planning and management rather than more integrated, longer-term perspectives, thus preventing viable, sustainable development. Over the years, the design of humanitarian settlements has not been adapted to local contexts and perspectives, nor to the dynamics of urbanization and population growth and data. In addition, the current approach to temporary settlement harms the environment and can strain limited resources. Inefficient land use and ad hoc development models have compounded difficulties and generated new challenges. As a result, living conditions in settlements have deteriorated over the last few decades and continue to pose new challenges. The stakes are such that major shortcomings have emerged along the way, leading to disruption, budget overruns in a context marked by a steady decline in funding. However, some attempts have been made to shift towards more sustainable approaches, but these have mainly focused on vague, sector-oriented themes, failing to consider systematic and integration views. This study is a contribution in addressing these shortcomings by designing a model-driving solution, emphasizing an integrated system conceptualized as a system of systems. This paper proposes a new methodology for designing an integrated and sustainable human settlement model, based on Model-Based Systems Engineering and a Systems Modeling Language to provide valuable insights toward sustainable solutions for displaced populations aligning with the United Nations 2030 agenda for sustainable development.展开更多

The development of urbanization has promoted the improvement of China's economic results. Therefore, it is necessary to effectively control the balance between urban land resources and human settlement needs. These factors are directly related to people's production and life. Therefore, this paper mainly analyzes and studies the main construction measures of human settlements in the process of urban and rural planning.展开更多

[Method] By constructing an evaluation index system of economy and human settlement, and using the coordinate measurement model of them, 22 county-level cities in the Yellow River Basin were analyzed. [Result] In the Yellow River Basin, the construction level of economy and human settlement in those county-level cities is low with distinct spatial differences and deteriorating polarization; there is a great spatial corresponding between coordinated development degree and economic level, the higher the economic development level, the higher coordinated development degree in county-level cities; county-level cities around the boundaries of provinces have difficulties in development. [Conclusion] Evaluation standards and models are clear in significance, convenient in application, which can successfully evaluate the coordination of human settlement development in the study region.展开更多

China landscape is so vast, dominated by rural areas. Human settlement environment of ancient villages is so important for studying domestic human settle- ment environment, including ancient structure analysis and eco-resource organization. The research explored Xichong Village, Sikou Town, Wuyuan County and detailed how to improve its environment, providing references for ancient village development in settlement environment.展开更多

Urban human settlement and economic systems exist in urban ecosystems, which are a structural complexity. Therefore the research is being challenged by some uncertain factors between human settlements and economic systems. However most of the researches were focused on its determinate objective aspects and qualitative analyses while less concern on the quanti- tative evaluation of coordinated development of urban human settlement environment and economy, especially little on its uncertain aspect. At present, the urgent task is to study the coordinated development of urban settlement environment and economy in terms of the effect of uncertainty. This study analyzed the uncertain characteristics, which would be confronted at different stages, such as confirming the index categories, their bound values, and their construction rate, etc. According to the actual urban conditions, many construction principles based on uncertainties are put forward and an indicating system for human settlement and economic evaluation is established. Moreover, the application of fuzzy mathematics presents a new method and a calculation model for the comprehensive assessment of the coordinated development of urban human settlement environment and economy. The application of the method and model in Changsha city of China showed that the assessment results can reflect not only the overall coordination degree of the city, but also the mode of interactive mechanism between urban economic system and human settlement environment.展开更多

Due to increasing demands for environment exploration and tourism, a large transitional area is required for altitude adaptation. Hehuang valley, which locates in the transition zone between the Loess Plateau and the Qinghai-Tibet Plateau, has convenient transportation and relatively low elevation. Our question is whether the geographic conditions here are appropriate for adapted stay before going into the Qinghai-Tibet Plateau. Therefore, in this study, we examined the potential use of ecological niche modeling （ENM） for mapping current and potential distribution patterns of human settlements. We chose the Maximum Entropy Method （Maxent）, an ENM which integrates climate, remote sensing and geographical data, to model distributions and assess land suitability for transition areas. After preprocessing and selection, the correlation between variables and spatial auto- correlation input data were removed and 106 occurrence points and 9 environmental layers were determined as the model inputs. The threshold- independent model performance was reasonable according to lO times model running, with the area under the curve （AUC） values being 0.917± 0.01, and 0.923±0.002 for test data. Cohen＇s kappa coefficient of model performance was 0.848. Results showed that 82.22% of the study extent was not suitable for human settlement. Of the remaining areas, highly suitable areas aceounted for 1.19%, moderately for 5.3% and marginally for 11.28%. These suitable areas totaled 418.79 km2, and 86.25% of the sample data was identified in the different gradient of suitable area.The decisive environmental factors were slope and two climate variables： mean diurnal temperature range and temperature seasonality. Our model showed a good performance in mapping and assessing human settlements. This study provides the first predicted potential habitat distribution map for human settlement in Ledu County, which could also help in land use management.展开更多

This model includes five subsystems: living, economy, society, ecology and engineering. The model simulates various scenarios, based on different parameter settings to predict the trend of human settlement from 2019–2040 in Changsha. It puts forward four development programs under different simulation scenarios. The results show that the current system of human settling lacks self-regulation and feedback, where simple increases in the economy and urbanization cannot drive the internal system to progress positively. In contrast, the resilient human settlement program is more reasonable and scientific, up to the year 2040, the production, living and ecological environment of residents will be markedly improved in terms of per capita disposable income, per capita floor space and medical insurance coverage;these will increase by 98.9%, 39.7%, and 170.7%, respectively. This system of developing resilient human settlement provides feedback according to the internal relation loops and thus drives itself to adjust and recover, achieving harmonious and sustainable development. In the forthcoming development, we should take the initiative to optimize economic development and upgrade industrial structures, establish emergency plans and response mechanisms to enhance human quality of life.展开更多

文摘Climate is one important environmental variable that affects human life.As the regions along the Belt and Road(B&R)encompass vast territories and large populations,it is significant to assess climate suitability for human settlements,which will influence the migration of various surrounding countries.We selected seven regions including 65 countries along the B&R for the research area and adopted the temperature-humidity index(THI),to assess the climate suitability.We analyzed the spatial characteristics of THI and the correlation between population distribution and THI,the results of which enabled us to adjust the THI classification criteria.We finally assessed the climate suitability of each region.The results reveal that outside the Qinghai-Tibet Plateau,the THI values generally tend to decrease from west to east as longitude increases and downward with increasing latitude.The population distribution is significantly correlated with the THI.Regions with relative suitable climate,including high suitability areas(HASs),moderately suitable areas(MSAs)and low suitability areas(LSAs),account for 50.62%of the total area and encompass in excess of 90%of total population.These areas are widely distributed in the southern regions of 45°N latitude,again with the exception of the Qinghai-Tibet Plateau.Critical suitable area includes 19.48%of the entire area and 8.98%of total population.The non-suitable area accounts for less than 30%of total area,concentrated in the cold high-latitude and high-altitude areas.

文摘Using the theories of population carrying capacity and ecological elasticity in other fields for reference, the connotation of regional human settlement system was defined from the viewpoint of the complex relationship among the factors such as regional population, resources, environment and economic and social development in the context of China′s rapid urbanization. Then the concept and characterization methods of the regional human settlement carrying capacity were proposed by means of population scale. Furthermore, a model of carrying capacity-pressure-state-response(CPSR) on regional human settlement system was established by referencing pressure-state-response(PSR) model, and the Catastrophe Theory was introduced to determine the corresponding standards of multi-criteria programming and evaluation. Taking Dalian City, Liaoning Province, China as an example, an empirical analysis on evaluation of human settlement system from 2000 to 2012 was carried out. The results showed that the carrying capacity of human settlement system in Dalian was fluctuating between 9.6 × 106 to 10 × 106 persons with a quantitative stage of the dynamic regulation. During the research period the load index of human settlement system in Dalian dropped from 0.96 to 0.84 with a lower pressure of human settlement system than the national average level. And the emergency response grades of human settlement system in Dalian were kept in grade Ⅱ(orange warning) or grade Ⅲ(yellow warning). Human settlement system of Dalian was in slight security state as a whole, but the load had a tendency of increase in recent years. The related departments should pay close attention to regional human settlement system and take active measures to improve human settlement by both intensity control and total quantity control. By comparison, analysis and discussion, it was considered that the results were basically accordded with the current situations of human settlement in Dalian, and the evaluation results were more reliable, visualized and easily applied in practice. Therefore, the above-mentioned concepts, characterization and evaluation methods of the regional human settlement system and carrying capacity could provide a new thought and method for quantitative evaluation of human settlement.
文摘Based on the data of rural human settlements in Licheng District of Jinan City in 2016,the evaluation system of rural human settlements composed of four subsystems（ social economy,infrastructure,public environment,and construction management） was constructed. According to the comprehensive scores of various administrative villages calculated by means of multi-index comprehensive evaluation method and fuzzy comprehensive evaluation method,the human settlements of 521 administrative villages in Licheng District were divided into four types： excellent,good,average,and poor. Moreover,the spatial differences in the evaluation results of rural human settlements were analyzed using GIS spatial analysis technology. Finally,based on the evaluation results of rural human settlements in Licheng District,some measures to improve and control rural human settlements in different types of villages at various development stages were proposed to fully improve the quality of rural human settlements.

文摘Urban geography has always been concerned about the influence of human settlements on urban vitality,but few studies reveal the influence of human settlements on urban vitality at a micro-scale.This paper analyzes the spatial distribution characteristics of human settlements’quality and urban vitality at the micro-scale using Geodetectors and geographic weighted regression to analyze the relationship between human settlements and urban vitality.The results are shown as follows:there is still a significant development space for human settlements quality in Shahekou District,with obvious spatial dependence characteristics and significant gaps between various systems;the urban vitality of Shahekou District has obvious timeliness,and the urban vitality undergoes significant changes over time,which is related to the human settlements quality.The spatial distribution presents a single core spatial distribution structure with strong relative stability.The spatial distribution of cold and hot spots shows a pattern of“high in the north and low in the south,high in the east and low in the west”,with an increasing trend from southwest to northeast;the reachability of public transport has a significant impact on urban vitality.Its synergy with other variables is the leading force forming the spatial distribution of urban vitality.The environmental system,support system and social system are the significant factors affecting the urban vitality of Shahekou District.
文摘The challenge of transitioning from temporary humanitarian settlements to more sustainable human settlements is due to a significant increase in the number of forcibly displaced people over recent decades, difficulties in providing social services that meet the required standards, and the prolongation of emergencies. Despite this challenging context, short-term considerations continue to guide their planning and management rather than more integrated, longer-term perspectives, thus preventing viable, sustainable development. Over the years, the design of humanitarian settlements has not been adapted to local contexts and perspectives, nor to the dynamics of urbanization and population growth and data. In addition, the current approach to temporary settlement harms the environment and can strain limited resources. Inefficient land use and ad hoc development models have compounded difficulties and generated new challenges. As a result, living conditions in settlements have deteriorated over the last few decades and continue to pose new challenges. The stakes are such that major shortcomings have emerged along the way, leading to disruption, budget overruns in a context marked by a steady decline in funding. However, some attempts have been made to shift towards more sustainable approaches, but these have mainly focused on vague, sector-oriented themes, failing to consider systematic and integration views. This study is a contribution in addressing these shortcomings by designing a model-driving solution, emphasizing an integrated system conceptualized as a system of systems. This paper proposes a new methodology for designing an integrated and sustainable human settlement model, based on Model-Based Systems Engineering and a Systems Modeling Language to provide valuable insights toward sustainable solutions for displaced populations aligning with the United Nations 2030 agenda for sustainable development.
文摘The continuous innovation and development of China's economic system promotes the continuous improvement of people's living and production level, and the quality of urban and rural construction planning also has higher requirements. The development of urbanization has promoted the improvement of China's economic results. Therefore, it is necessary to effectively control the balance between urban land resources and human settlement needs. These factors are directly related to people's production and life. Therefore, this paper mainly analyzes and studies the main construction measures of human settlements in the process of urban and rural planning.

文摘The construction of human settlements plays a vital role in achieving sustainable development goals.With the growing population,both urban and rural planning—as well as the development of human settlements—on the Qinghai-Tibet Plateau in China have received increasing attention.This study proposed a comprehensive framework to assess the quality of human settlements and identify their limiting factors of Nyingchi City,southeastern Qinghai-Tibet Plateau of China.The framework integrated a region-specific evaluation system tailored to the plateau’s unique characteristics and utilized multi-source data collected through field-based questionnaires and remote sensing.Analytical methods employed include the Criteria Importance Through Intercriteria Correlation(CRITIC)weighting method,difference analysis for evaluating spatial and categorical variations,and a novel approach introduced in this study for identifying limiting factors.In August 2021,a questionnaire-based survey was conducted in the southeastern Qinghai-Tibet Plateau,yielding 823 valid responses.The average evaluation score for human settlement quality(HSQ)was(6.96±0.94),indicating that settlement conditions were approaching the satisfaction threshold.Notably,the score for the health dimension was(6.28±1.41),reflecting relatively underdeveloped health services in the region.From the perspective of spatial patterns,despite its favorable natural conditions,the HSQ in Medog County was relatively backward,reflecting uncoordinated development that warrants attention.Significant differences were observed in the perceptions of human settlements among different groups in terms of ethnicity,income,and educational background.Low ratings for income and employment conditions represented a major limitation to the local HSQ.The development of human settlements in the southeastern Qinghai-Tibet Plateau still needs further promotion due to population disparities and the challenges of creating a healthy environment in high-altitude regions.The results are valuable for improving human settlements in plateau regions,which can help make targeted policy recommendations.

文摘[Objective] To provide quantification means for comprehensively analyzing the coordinated development of urban human settlement and economy by constructing an index system of economy and human settlement. [Method] By constructing an evaluation index system of economy and human settlement, and using the coordinate measurement model of them, 22 county-level cities in the Yellow River Basin were analyzed. [Result] In the Yellow River Basin, the construction level of economy and human settlement in those county-level cities is low with distinct spatial differences and deteriorating polarization; there is a great spatial corresponding between coordinated development degree and economic level, the higher the economic development level, the higher coordinated development degree in county-level cities; county-level cities around the boundaries of provinces have difficulties in development. [Conclusion] Evaluation standards and models are clear in significance, convenient in application, which can successfully evaluate the coordination of human settlement development in the study region.
文摘As urbanization continues, traditional villages are confronted by the conflict between protection and development, especially for ancient villages in living envi- ronment. China landscape is so vast, dominated by rural areas. Human settlement environment of ancient villages is so important for studying domestic human settle- ment environment, including ancient structure analysis and eco-resource organization. The research explored Xichong Village, Sikou Town, Wuyuan County and detailed how to improve its environment, providing references for ancient village development in settlement environment.

文摘The coordinated development of human settlement environment and economy is of vital significance to urban sustainable development and urban ecosystem health. Urban human settlement and economic systems exist in urban ecosystems, which are a structural complexity. Therefore the research is being challenged by some uncertain factors between human settlements and economic systems. However most of the researches were focused on its determinate objective aspects and qualitative analyses while less concern on the quanti- tative evaluation of coordinated development of urban human settlement environment and economy, especially little on its uncertain aspect. At present, the urgent task is to study the coordinated development of urban settlement environment and economy in terms of the effect of uncertainty. This study analyzed the uncertain characteristics, which would be confronted at different stages, such as confirming the index categories, their bound values, and their construction rate, etc. According to the actual urban conditions, many construction principles based on uncertainties are put forward and an indicating system for human settlement and economic evaluation is established. Moreover, the application of fuzzy mathematics presents a new method and a calculation model for the comprehensive assessment of the coordinated development of urban human settlement environment and economy. The application of the method and model in Changsha city of China showed that the assessment results can reflect not only the overall coordination degree of the city, but also the mode of interactive mechanism between urban economic system and human settlement environment.

文摘The Qinghai-Tibet Plateau is the word＇s highest and largest plateau. Due to increasing demands for environment exploration and tourism, a large transitional area is required for altitude adaptation. Hehuang valley, which locates in the transition zone between the Loess Plateau and the Qinghai-Tibet Plateau, has convenient transportation and relatively low elevation. Our question is whether the geographic conditions here are appropriate for adapted stay before going into the Qinghai-Tibet Plateau. Therefore, in this study, we examined the potential use of ecological niche modeling （ENM） for mapping current and potential distribution patterns of human settlements. We chose the Maximum Entropy Method （Maxent）, an ENM which integrates climate, remote sensing and geographical data, to model distributions and assess land suitability for transition areas. After preprocessing and selection, the correlation between variables and spatial auto- correlation input data were removed and 106 occurrence points and 9 environmental layers were determined as the model inputs. The threshold- independent model performance was reasonable according to lO times model running, with the area under the curve （AUC） values being 0.917± 0.01, and 0.923±0.002 for test data. Cohen＇s kappa coefficient of model performance was 0.848. Results showed that 82.22% of the study extent was not suitable for human settlement. Of the remaining areas, highly suitable areas aceounted for 1.19%, moderately for 5.3% and marginally for 11.28%. These suitable areas totaled 418.79 km2, and 86.25% of the sample data was identified in the different gradient of suitable area.The decisive environmental factors were slope and two climate variables： mean diurnal temperature range and temperature seasonality. Our model showed a good performance in mapping and assessing human settlements. This study provides the first predicted potential habitat distribution map for human settlement in Ledu County, which could also help in land use management.

文摘Using the system dynamics simulation software Vensim PLE, we built a model to simulate the development of resilient human settlement in Changsha. This model includes five subsystems: living, economy, society, ecology and engineering. The model simulates various scenarios, based on different parameter settings to predict the trend of human settlement from 2019–2040 in Changsha. It puts forward four development programs under different simulation scenarios. The results show that the current system of human settling lacks self-regulation and feedback, where simple increases in the economy and urbanization cannot drive the internal system to progress positively. In contrast, the resilient human settlement program is more reasonable and scientific, up to the year 2040, the production, living and ecological environment of residents will be markedly improved in terms of per capita disposable income, per capita floor space and medical insurance coverage;these will increase by 98.9%, 39.7%, and 170.7%, respectively. This system of developing resilient human settlement provides feedback according to the internal relation loops and thus drives itself to adjust and recover, achieving harmonious and sustainable development. In the forthcoming development, we should take the initiative to optimize economic development and upgrade industrial structures, establish emergency plans and response mechanisms to enhance human quality of life.
