In this context, the present study had three related research aims. Firstly, it sought to predict the urbanization and population dynamics in China at both national and provincial levels for the period of 2015 to 2030. Secondly, on this basis, it sought to examine the spatial variation of urbanization given the predicted national urbaniza- tion rate of 70.12%. Thirdly, it sought to estimate and evaluate the national and provincial demands of investment in the development of new-type urbanization. The main conclusions from this study were as follows： （1） The population size and urbanization rate will reach 1.445 billion and 70.12%, respectively, from 2015 to 2030. （2） The demographic dividend will vanish when the population pressure reaches its maximum. During this period, there will be 70.16 million urban population born. The suburban population that becomes urbanized will be 316.7 million, and thus the net increase in urban population will reach 386 million. （3） Although the urbanization rate of every Chinese province will increase during 2015-2030, it will do so un- equally, while differences in urbanization quality among provinces will also be substantial. In some provinces, moreover, the urbanization quality is not compatible with their eco-social development. （4）A total of 4,105,380 billion yuan is required to fund new-type urbanization and the investment demand for each province varies greatly; for example, Guangdong prov- ince requires the most funding, amounting to approximately 148 times that required by Tibet, the province in least need of funding. In the final part of this study, policy suggestions con- cerning the investment of the new-type urbanization are put forward and discussed.展开更多

This study uses survey data from rural migration laborers across the eastern, central, and western China to construct a comprehensive labor migration stability index, and compares the determinants of the migration stability of rural labor among cities and industries using Geodetector. The results are as follows: 1) Compared with the midwestern cities, eastern cities have attracted younger and more skilled rural labor, and industries with higher technical content have higher migration stability among rural laborers. 2) Rural laborers more often adapt to changes by changing employment instead of changing working-cities. 3) The individual experiences of rural laborers and urban characteristics have significant impacts on the stability of migration, and family and societal guanxi(Chinese interpersonal relationships) enhance migration stability. 4) A unified labor market and convenient transportation have somewhat slowed industrial transfers and labor backflow. This study enhances our understanding of the roles of industrial transfer and new-type urbanization in shaping the labor geography landscape and provides policy implications for the promotion of people-oriented urbanization.展开更多

Based on the land-use change data, this paper analyzes the characteristics of land use change and its driving factors in Guiyang with the method of land-use dynamic analysis, land utilization and factor correlation analysis. We get the following results:(1) the change of land use was obvious during 2004 and 2012. The area of arable land and other land were decreased, the rate of decrease are 3.89% and 8.24%. In the meantime, a series of construction land and forest area increased a lot, the rate of increase are 3.89% and 8.24%.(2) The integrated land use dynamic degree of two research stages(2004-2009 and 2009-2012) were decreased from 2.12% to 0.34%, this suggests dynamic changes of land tend to be stable.(3) Four kinds of Land use class have a great contribution to the index of land use degree respectively. The composite index of land use degree rose from 229.58 to 247.19 during 2004 and 2012; the land use is still in the development stage.(4) Economy, population, transportation and policy guidance are the main drivers of land use change.展开更多

Firstly,as people are the core of human settlements,urbanization should show its care for humans and thus for human settlements; secondly,a human settlement civilization should be cultivated on the basis of ecological civilization; thirdly,rural development should be promoted in units of county,in order to coordinate the urban-rural development; fourthly,it should encourage the decision-makers and think tanks to improve the management mechanism. As transformation becomes the general trend of this era,we need also to understand the Sciences of Human Settlements from the perspective of scientifi c transformation,which is expected to break new grounds in the Sciences of Human Settlements.展开更多

文摘Rapid urbanization in China has led to inefficient use of urban land and spatial structure disorder,attracting attention from academia and society.Taking the Yangtze River Delta,China as an example,this study constructed an index evaluation system that quantitatively analyses the impact of new-type urbanization(NTU)on urban land use efficiency(ULUE)from 2000 to 2020 using a panel data vector autoregressive model.The results show that NTU in the Yangtze River Delta promotes ULUE improvement.However,the promotion of NTU to ULUE is limited,and the level of urban economic development also plays a role in promoting the change of ULUE.Moreover,the study further analyzed the results of urbanization decomposition and found that population urbanization(PU),economic urbanization(EU),spatial urbanization(SU),and social urbanization(SCU)can explain changes in ULUE in the Yangtze River Delta to a certain extent.In terms of variance decomposition,PU contributed the most to ULUE,followed by EU,SU,and SCU.Some necessary measures should be taken to coordinate the development of different types of urbanization,improve the sustainable utilization level of land resources,and provide a reference for high-quality development in the Yangtze River Delta.
文摘At present, with the new urbanization as the background of the situation in our country, local governments in China especiallyin the central region as the representative of Henan Province, is to take this opportunity to create their own economic heights and industrialagglomeration, and constantly improve the level of urbanization of the original, but the town level cannot improve open the power of capital, thelocal government of is facing fi nancing, fi nancing platform, fi nancing channels and fi nancing policy and a series of fi nancing systems caused byfi nancing diffi culties. Therefore, as the perspective of the local government, a new study of investment and fi nancing system and the risk measure,can more effectively guide and encourage the existing capital city infrastructure and public services to improve the fi eld.

文摘With the large-scale population flow between regions and the gradual disappearance of the“demographic dividend,”promoting the accumulation of higher education human capital and leveraging the“talent dividend”have become the important driving forces for the development of new-type urbanization.Therefore,understanding the relationship between higher education human capital and new-type urbanization is a scientific issue that needs to be addressed.The results of this study demonstrate three features of that relationship:(1)From 2010 to 2020,the level of higher education human capital in Guizhou Province showed a continuous increase and a spatial distribution pattern of gradual decline in a stepwise“central-northwest-southeast”manner.(2)From 2010 to 2020,the level of new-type urbanization in Guizhou Province gradually increased,forming a dual-core development pattern with the“Qianzhong Urban Cluster”and the“Zunyi Metropolitan Area”.Overall,it exhibited a spatial distribution pattern of gradual decline from northwest to southeast.(3)Threshold effect model results indicate that higher education human capital promotes new-type urbanization when below a single threshold or above a double threshold,but hinders it when between these thresholds.This results in an“N”-shaped developmental relationship.
文摘As urbanization is an evolutionary process of the open giant system of complex spaces,solutions should be sought based on the scientifi c method of "limited solutions to complex problems." Firstly,as people are the core of human settlements,urbanization should show its care for humans and thus for human settlements; secondly,a human settlement civilization should be cultivated on the basis of ecological civilization; thirdly,rural development should be promoted in units of county,in order to coordinate the urban-rural development; fourthly,it should encourage the decision-makers and think tanks to improve the management mechanism. As transformation becomes the general trend of this era,we need also to understand the Sciences of Human Settlements from the perspective of scientifi c transformation,which is expected to break new grounds in the Sciences of Human Settlements.

文摘The rapid population and land urbanization not only promoted economic development but also affected the ecosystem service value(ESV).In the context of new-type urbanization and green development,it’s essential to investigate the impacts of urbanization on ESV in China.However,a comprehensive and dynamic framework to reveal the relationship between ESV and urbanization processes is lacking.This study adopted multi-source datasets to portray China’s urbanization process by integrating population,land,and economic urbanization,eval-uated the ESV changes of 10 categories by gross ecosystem product(GEP)methods,and explored ESV changes within different urbanization scales and speeds.The results showed rapid urbanization in the population,land,and economic dimensions in China,with a faster process of economic urbanization.The ESV also exhibited an increasing trend,with higher levels in the southeastern coastal regions and lower levels in the northwestern regions.Urbanization had positive impacts on ESV across various research units,but the ESV exhibited heteroge-neous changes across different urbanization scales,speeds,and their interactive effects.The response of ESV to dynamic urbanization processes was influenced by socio-economic,ecological,and policy factors;it is essential to combine targeted measures with general ecological product value realization methods in each unit to maximize social-economic-ecological benefits.

文摘Dryland regions face complex interactions between urbanization and ecological changes,where effective coordination is essential for enhancing sustainability and resilience.However,most studies concentrate on the national or provincial scales,with insufficient research on county-level coordination,limiting the ability to provide targeted polifrom a precise perspective.This study addresses this gap by analyzing 39 counties within the Hohhot-Baotou-Ordos-Yulin Urban Agglomeration(HBOYUA),a typical dryland urban cluster in China.We use daytime and nighttime remote sensing images to track the spatio-temporal evolution of urbanization and ecological conditions from 1992 to 2023.A novel quantitative framework based on an improved coupling coordination degree(CCD)is proposed to assess their coordination relationship.The results reveal that:(1)Urbanization and ecological quality both exhibited fluctuating upward trends,with spatial heterogeneity increasing for urbanization and decreasing for the eco-environment.Regions with better ecological conditions had higher urbanization levels.(2)The overall coordinated level improved from imbalance(0.36)to low-level coordination(0.55),although its spatial distribution remained uneven,with central urban areas showing higher CCD than surrounding counties.(3)Socioeconomic factors exerted greater effects on CCD than natural factors,with GDP and land surface temperature(LST)playing a significant role in interaction analysis.(4)In western arid regions,urbanization did not necessarily harm ecosystems;instead,ecological conditions improved alongside urbanization.This research offers targeted and valuable references for county and city governments in resource allocation and sustainable development.The proposed methodology is also adaptable for urban resilience studies in other regions.

文摘Urbanization’s impact on pre-monsoon extreme rainfall in the Greater Bay Area(GBA),coastal South China(SC),and its relation to different synoptic systems remains understudied.This research investigates urbanization effects on premonsoon rainfall using hourly station observations and Weather Research and Forecasting model with the Single Layer Urban Canopy Model(WRF-SLUCM)simulations.Observations show stronger pre-monsoon extreme rainfall in GBA cities than surrounding rural areas,with the urban heat island(UHI)intensifying the urban rainfall intensity and probability.Extreme cases were classified into frontal and shear-line warm-sector types.Enhanced urban rainfall due to UHI was more pronounced under shear-line and warm-sector systems.Four frontal and four shear-line cases were dynamically downscaled using WRF-SLUCM,and four parallel experiments were conducted:“Nourban”(urban areas replaced by cropland),“AH0”,“AH100”,and“AH300”[normal land use,with the diurnal maximum anthropogenic heat(AH)set to 0,100,and 300 W m^(−2)in SLUCM,respectively].In frontal cases,significantly reduced urban rainfall in AH0 is due to decreased(enhanced)surface evaporation(wind divergence)in cities compared to cropland.Strong northerly winds and cold-air intrusion suppress the UHI in AH0 and AH100 during the rainfall process;enhanced urban rainfall occurs only in AH300.In contrast,for shear-line cases,urban friction and UHI promote local convection and wind convergence,increasing urban rainfall significantly in all urban experiments compared to Nourban.Overall,urbanization’s influence on SC’s premonsoon extreme rainfall is highly sensitive to the type of synoptic systems,necessitating further investigation of urban rainfall in this season.

文摘A comprehensive understanding of urbanization impacts on landscape dynamics,eco-environmental consequences,and advancements in human habitation is paramount for effectively advancing urbanization-related sustainable development goals.This study predicted the urbanization process within the Hohhot-Baotou-Ordos-Ulanqab(HBOU)region and its projected implications for ecology,human settlement,and energy consumption in 2020–2050 using multi-source data and models under Shared Socioeconomic Pathways(SSPs).The results revealed that the HBOU region's urban area grew by 624.66 km~2 between 1990 and 2020.By 2050,it is expected to reach 1793.49±169.30 km~2,mainly expanding into cropland(58.95%)and natural ecological land(31.79%).Urban greening is projected to enhance,with the highest urban green space(UGS)predicted under SSP1(32.42%).Under this scenario,the per capita urban area(PCUA)and per capita urban green space area(PCUGA)are projected to reach 172.66 and 55.63 m~2/person in 2050,respectively.Furthermore,the ecological and energy utilization impacts are anticipated to decrease by 3.99%to 37.52%relative to alternative scenarios.Our projections suggest that limiting urbanization area in the HBOU region to 1500–1600 km~2 would significantly enhance the settlement environment and mitigate ecological and energy consumption effects.These results guide urban strategies balancing ecology,energy use,and habitation in arid regions.
文摘This study examines the impact of urbanization on the Surface Urban Heat Island(SUHI)effect in the Bangkok Metropolitan Region(BMR)over a 36-year period,utilizing advanced machine learning techniques to assess changes in land use and land cover(LULC).The research addresses three key questions:(1)How have changes in LULC influenced the dynamics of the urban heat island(UHI)effect in the BMR?(2)What roles do green and blue infrastructure play in mitigating urban heat?(3)How effectively can machine learning models classify LULC changes and provide insights to support sustainable urban planning?The findings reveal a strong correlation between urban growth and increased land surface temperatures(LST),with parks and water bodies exhibiting lower LSTs,emphasizing the importance of green and blue infrastructure in mitigating urban heat.The SUHI effect,initially measured at 3℃ from 1988 to 1991,peaked at 4.8℃ between 2012 and 2019 before slightly declining to 4.1℃ in recent years due to urban greening initiatives.However,ongoing urban development continues to diminish green spaces and water bodies,underscoring the urgent need for sustainable urban planning.Economic factors,including the 1997 Asian Financial Crisis and land tax laws introduced in 2019,influenced land use patterns,further exacerbating the SUHI effect.The research highlights the necessity of integrated urban management and sustainable land use policies to enhance climate resilience in rapidly urbanizing regions like the BMR.
