This study from different perspectives designed the alternatives for Changchun＇s county-level road and urban road system planning, and used the method of System Dynamics to simulate, optimize and analyze those alternatives. Thereafter, some methods including the correlation function method were used to comprehensively assess and rank those alternatives for recommending two best alternatives with the consideration to the indicators, such as the total emission amount of CO, the total emission amount of nitrogen oxides, the noise value, the road construction cost, the fossil oil consumption and the traffic capacity. The result showed that the study would provide substantial supports for decision-makers to make more scientific decisions and promote the sustainable urban traffic in Changchun City.展开更多

Strategic environmental assessment (SEA) is a systematic and comprehensive process for evaluating the environmental impacts of a policy,plan or program in publicly accountable decision-making. Air pollution has been recognized as a significant issue in most transport SEA practices. The Strategic Environmental Assessment of the Hubei Road Network Plan (2002-2020) (HRNP) was introduced as one of the World Bank's pilot SEA projects. An effective framework was developed to investigate the functional relationship between the road network and its potential air pollutant emissions. In this study,two indicators were identified:emission intensity/ inventory of pollutants and the spatial distribution of the most polluted areas. Because strategic actions are inherently nebulous and data quality is often disappointing,three alternative scenarios were employed to address uncertainties and data/scale issues. Calculations were made using emission models and results were analyzed with the help of statistical tools and the geographic information system (GIS). The results from the project implementation and the feedback from the World Bank have both shown that the proposed framework is effective in the transport SEA process.展开更多

In particular there is now a strong demand for information about the environment to be linked to information about the impacts of human activities so that the unsustainable aspects of economic development can be anticipated and controlled. The scope of environmental assessment has enlarged to provide information that will help a wide range of stakeholders, including business and publics to make decisions, choosing between alternatives on the basis of sound environmental information set in a social and economic context. This paper provides a discussion of these developments and illustrates how integrated environmental assessment of a specific urban environmental problem, the reduction of health impacts of air borne particles, can deliver broad strategic information for participants in the solution.展开更多

In this paper, the origin and the present research-conditions of public participation in SEA were analyzed. And the necessity of public participation was illuminated from following three aspects: 1) the public participation in China′s SEA is a key method of gaining the public support; 2) the public participation is one important source of gaining information; 3) the public participation is a good way to overcome the obstruction in the traditional mechanism of making strategy decision. Effective public participation should be involved in the whole process of SEA, and the public participators should include the public representatives of the groups affected by environmental change, the specialists in SEA and relevant fields, persons who are interested in the strategy and media, and so on. Various methods of public participation in SEA, including the methods of obtaining information and information feedback or consultation, were discussed. Further, the function, the advantages and the disadvantages of each method were discussed in detail, too.展开更多

The intense natural resources utilization and increasing population has brought great pressure, especially in coastal areas, consequently affecting the sustainable development of coastal cities. In 2002, Environmental Impact Assessment Act (EIA Act) was enacted in China. Environmental impact assessment targeted at planning, one level of strategic environmental assessment (SEA), thus became a legislative requirement. This paper considers SEA to be one of the important approaches not only to control coastal pollution, but also to conserve coastal ecosystems and finally to achieve sustainable development during urbanization, thus it will be a set an example for other areas of China. The experience of SEA in Xiamen, a coastal city in southeast China, illustrates the potentials of SEA. This paper first briefly introduces the concept and potentials of SEA, then compares two SEA cases and a project EIA case in Xiamen, and finally identifies the key characteristics of SEA.展开更多

The criteria of sustainability are included in building environmental assessment systems and tools used in different countries. The aim of building environmental assessment is a sustainable building design, which demands the cooperation among civil engineers, architects, environmentalists and other experts from different areas of building environmental assessment. The existing systems and tools were the basis of the new system development available in Slovak conditions. The purpose of this paper is to introduce the building environmental assessment system （BEAS） which was developed in Slovakia. Significant models used world wide in relation to environmental assessment of buildings, were compared on the basis of their covered. The summary of sustainable building assessment systems will be presented in this paper. Developing a building environmental assessment system for Slovakia is also introduced in the paper.展开更多

It is of highly significance to improve decision-making. This article reviewed the researches on SEA as well as its practices in Taiwan, Hong Kong and the mainland of China. The regulations, methodologies, and effect of practices were compared. The regulations on SEA had been enacted at three places respectively. With the largest spatial area and rapid economic development pace, the mainland has carded out more SEA practices recently than the other two places, but their final effect still need to be confirmed. It was said that Hong Kong had acquired considerable experiences on SEA, while practice of SEA at Taiwan lagged behind.展开更多

Thus, to pursue a broader course of sustainable development, the Chinese government has attached more and more importance to SEA. Strategic Environmental Assessment （SEA） is a frontier subject in the field of Environmental Impact Assessment （EIA）. This article describes the current situation of SEA in China, discusses major problems with SEA, and then recommends improvements in the system. EIA Act of the People＇s Republic of China was promulgated which explicitly provides SEA is required in regional and sector plans and programs. In order to promote comprehensive development of SEA, a lot of work has been done by SEPA. Some SEA ＂experiments＂ have been implemented, and some research has been conducted on the topic in China. But SEA as applied today in China is confronted with a host of methodological and institutional limitations. Moreover, public participation is often extremely limited, because the system restricts public participation. Policies and strategies are kept secret from the public. Most of the research has been focused on the concept, theory, and framework of SEA. Comprehensive application of SEA in China has yet to occur, and only a limited number of case studies are available. We believe SEA can be improved by the following recommendations： dividing SEA into two stages, formulating legislation to safeguard the funds for SEA, guiding actively the public to participate in SEA, completing basic data bank about SEA, and setting up Hall for Workshop of Meta-synthetic Engineering for SEA.展开更多

This method may be applied using an electronic tool, which is in a development stage. Amending different assessment versions of the adaptive method is done by including the variables effect, according to set of steps, such as modifying the formulation of the assessment items, adjusting their estimation weights, and amending their achievement evaluation levels and their returned scores. When using the adaptive method, the assessment result of a building using a certain version differs from the results using other versions, even in the same country, so configuring an appropriate version due to the variables affecting the assessment helps getting more accurate results than the ones currently provided. The main goal of that research is to introduce the adaptive method that is proposed to ensure a fairer assessment results from the perspective of Green Architecture, and allow a more credible and accuracy of results comparison according to the environmental performance of buildings. The researcher analyzed the different main features she used in developing the adaptive method, the Comparative aspects between it and the current assessment methods, and the expected reached advantages from its usage. The paper arrived to the importance of adapting the environmental assessment of buildings according to the different affecting variables, and recommended developing the adaptive method and its tool to the stage of application to benefit its advantages.展开更多

Assessing leachate contamination in the subsoil is considered a complex process that needs detailed field measurement to accurately define the extent of contamination. To ascertain the extent of pollution of the subsoil and groundwater sources which were reportedly contaminated by leachate plumes from an old dumpsite located in Osubi town, an integrated geo-electrical method involving 1-D vertical electrical sounding (VES) and 2-D, 3-D ERT techniques were employed. Orthogonal set of 2-D apparent resistivity data was collected in a 100 × 50 m<sup>2</sup> rectangular grid around the dumpsite, using the Wenner array. Two years later, three (3) 2-D resistivity imaging profiles were also recorded in time-lapse mode at the dumpsite to monitor the possible effects of attenuation on the leachate over time. Ten (10) VES data were also acquired and used along with the 2-D imaging data. 2-D apparent resistivity data were inverted with Dipprowin software program. The orthogonal set of 2-D lines of apparent resistivity was merged into 3-D data and inverted with RES3DINV program to create a 3-D subsurface resistivity model. Geological models observed from 2-D and 3-D resistivity inversion revealed low resistivity values in the order ρ Ω·m which is indicative of leachate plumes in the saturation zone (pore water). The 2-D resistivity-depth sections imaged low resistivity leachate plumes at the near surface (<5 m) to a depth of 25.0 m, while 3-D inversion depth slices imaged leachate contaminant within the first, second and third layers at depth ranging from 0.00 - 2.50 m, 2.50 - 5.38 m and 5.38 - 8.68 m respectively. Thus, leachate contamination clearly increased with depth beyond the depth of first and second aquifers in the area which implies that available groundwater for domestic use is already contaminated with leachate from the dumpsite. Leachate contaminant-depth map estimated for the second geoelectric layers for VES 2, 3, 4, 7, 8, 9, and 10 shows that the second layer has been invaded completely by leachate contamination up to 6.5 m depth. 2-D apparent resistivity data acquired two years after show lower resistivity anomalies of the leachate plume caused by time-lapse attenuation effect on the observed resistivity of the leachate. This indicates that the leachate plume has become more conductive and toxic to the environment. The Longitudinal conductance map of the area shows that the aquifer protective capacity of this area is weak (0.1 - 0.19 Mho) thus, aquifers in the area are prone to pollution from the dumpsite. The three techniques used in this study (2-D, 3-D ERT and 1-D VES) fitly provided crucial information on the degree of contamination caused by the landfill leachate plume. Therefore, it is advisable to implement an environmental remediation and leachate management program.展开更多

文摘Recently, there has been growing concerns about environmental issues related to urbanization in China. The intense natural resources utilization and increasing population has brought great pressure, especially in coastal areas, consequently affecting the sustainable development of coastal cities. In 2002, Environmental Impact Assessment Act (EIA Act) was enacted in China. Environmental impact assessment targeted at planning, one level of strategic environmental assessment (SEA), thus became a legislative requirement. This paper considers SEA to be one of the important approaches not only to control coastal pollution, but also to conserve coastal ecosystems and finally to achieve sustainable development during urbanization, thus it will be a set an example for other areas of China. The experience of SEA in Xiamen, a coastal city in southeast China, illustrates the potentials of SEA. This paper first briefly introduces the concept and potentials of SEA, then compares two SEA cases and a project EIA case in Xiamen, and finally identifies the key characteristics of SEA.

文摘In the previous time the requirements of environmental safety, suitability and responsibility of buildings have increased. The criteria of sustainability are included in building environmental assessment systems and tools used in different countries. The aim of building environmental assessment is a sustainable building design, which demands the cooperation among civil engineers, architects, environmentalists and other experts from different areas of building environmental assessment. The existing systems and tools were the basis of the new system development available in Slovak conditions. The purpose of this paper is to introduce the building environmental assessment system （BEAS） which was developed in Slovakia. Significant models used world wide in relation to environmental assessment of buildings, were compared on the basis of their covered. The summary of sustainable building assessment systems will be presented in this paper. Developing a building environmental assessment system for Slovakia is also introduced in the paper.
文摘Strategic environmental assessment （SEA） is the process to evaluate, in a systematic way, the possible environmental impacts caused by decision making such as policy, plan, and program. It is of highly significance to improve decision-making. This article reviewed the researches on SEA as well as its practices in Taiwan, Hong Kong and the mainland of China. The regulations, methodologies, and effect of practices were compared. The regulations on SEA had been enacted at three places respectively. With the largest spatial area and rapid economic development pace, the mainland has carded out more SEA practices recently than the other two places, but their final effect still need to be confirmed. It was said that Hong Kong had acquired considerable experiences on SEA, while practice of SEA at Taiwan lagged behind.
文摘In the past three decades, especially in recent years, the environment has unceasingly deteriorated with rapid development of Chinese economy, and the inherent limitations of conventional project EIA have come to light. Thus, to pursue a broader course of sustainable development, the Chinese government has attached more and more importance to SEA. Strategic Environmental Assessment （SEA） is a frontier subject in the field of Environmental Impact Assessment （EIA）. This article describes the current situation of SEA in China, discusses major problems with SEA, and then recommends improvements in the system. EIA Act of the People＇s Republic of China was promulgated which explicitly provides SEA is required in regional and sector plans and programs. In order to promote comprehensive development of SEA, a lot of work has been done by SEPA. Some SEA ＂experiments＂ have been implemented, and some research has been conducted on the topic in China. But SEA as applied today in China is confronted with a host of methodological and institutional limitations. Moreover, public participation is often extremely limited, because the system restricts public participation. Policies and strategies are kept secret from the public. Most of the research has been focused on the concept, theory, and framework of SEA. Comprehensive application of SEA in China has yet to occur, and only a limited number of case studies are available. We believe SEA can be improved by the following recommendations： dividing SEA into two stages, formulating legislation to safeguard the funds for SEA, guiding actively the public to participate in SEA, completing basic data bank about SEA, and setting up Hall for Workshop of Meta-synthetic Engineering for SEA.
文摘The idea behind this work is developing an adaptive method for the environmental assessment of buildings, to configure different versions according to the variables affecting them (spatial, temporal and associated with building characteristics) to suit different evaluated projects. This method may be applied using an electronic tool, which is in a development stage. Amending different assessment versions of the adaptive method is done by including the variables effect, according to set of steps, such as modifying the formulation of the assessment items, adjusting their estimation weights, and amending their achievement evaluation levels and their returned scores. When using the adaptive method, the assessment result of a building using a certain version differs from the results using other versions, even in the same country, so configuring an appropriate version due to the variables affecting the assessment helps getting more accurate results than the ones currently provided. The main goal of that research is to introduce the adaptive method that is proposed to ensure a fairer assessment results from the perspective of Green Architecture, and allow a more credible and accuracy of results comparison according to the environmental performance of buildings. The researcher analyzed the different main features she used in developing the adaptive method, the Comparative aspects between it and the current assessment methods, and the expected reached advantages from its usage. The paper arrived to the importance of adapting the environmental assessment of buildings according to the different affecting variables, and recommended developing the adaptive method and its tool to the stage of application to benefit its advantages.
文摘Leachate plumes from landfills are a major source of pollution in Nigeria, especially in urban areas. Assessing leachate contamination in the subsoil is considered a complex process that needs detailed field measurement to accurately define the extent of contamination. To ascertain the extent of pollution of the subsoil and groundwater sources which were reportedly contaminated by leachate plumes from an old dumpsite located in Osubi town, an integrated geo-electrical method involving 1-D vertical electrical sounding (VES) and 2-D, 3-D ERT techniques were employed. Orthogonal set of 2-D apparent resistivity data was collected in a 100 × 50 m<sup>2</sup> rectangular grid around the dumpsite, using the Wenner array. Two years later, three (3) 2-D resistivity imaging profiles were also recorded in time-lapse mode at the dumpsite to monitor the possible effects of attenuation on the leachate over time. Ten (10) VES data were also acquired and used along with the 2-D imaging data. 2-D apparent resistivity data were inverted with Dipprowin software program. The orthogonal set of 2-D lines of apparent resistivity was merged into 3-D data and inverted with RES3DINV program to create a 3-D subsurface resistivity model. Geological models observed from 2-D and 3-D resistivity inversion revealed low resistivity values in the order ρ Ω·m which is indicative of leachate plumes in the saturation zone (pore water). The 2-D resistivity-depth sections imaged low resistivity leachate plumes at the near surface (<5 m) to a depth of 25.0 m, while 3-D inversion depth slices imaged leachate contaminant within the first, second and third layers at depth ranging from 0.00 - 2.50 m, 2.50 - 5.38 m and 5.38 - 8.68 m respectively. Thus, leachate contamination clearly increased with depth beyond the depth of first and second aquifers in the area which implies that available groundwater for domestic use is already contaminated with leachate from the dumpsite. Leachate contaminant-depth map estimated for the second geoelectric layers for VES 2, 3, 4, 7, 8, 9, and 10 shows that the second layer has been invaded completely by leachate contamination up to 6.5 m depth. 2-D apparent resistivity data acquired two years after show lower resistivity anomalies of the leachate plume caused by time-lapse attenuation effect on the observed resistivity of the leachate. This indicates that the leachate plume has become more conductive and toxic to the environment. The Longitudinal conductance map of the area shows that the aquifer protective capacity of this area is weak (0.1 - 0.19 Mho) thus, aquifers in the area are prone to pollution from the dumpsite. The three techniques used in this study (2-D, 3-D ERT and 1-D VES) fitly provided crucial information on the degree of contamination caused by the landfill leachate plume. Therefore, it is advisable to implement an environmental remediation and leachate management program.

文摘Land desertification,water scarcity,and food security challenges in arid zones are intensifying,driving the need for sustainable agricultural solutions like aquaponics.This study investigated innovative water and energy-saving strategies using an integrated dynamic model for an on-demand industrial aquaponics system in Israel.The model evaluated the performance of a recirculating aquaculture system(RAS),hydroponics system(HPS),and desalination unit(DU)by adjusting physical and operational parameters to optimize water and nutrient use efficiency,energy consumption,and yield.Optimizing the system design resulted in an aquaponics system with approximately 420 m^(3)RAS,6.85 ha HPS and 40 m^(3)/d DU,achieving phosphorus use efficiency of 96%,a water use efficiency of 97%,freshwater input of 1.5 L/day/m^(2),and energy consumption of 0.56 kWh/day/m^(2).To mitigate the challenges of extreme arid climates,evaporative cooling combined with outdoor shading and mechanical cooling was found to be a feasible option to control temperature and humidity in the greenhouse.Dehumidification technologies further improved system performance by recovering 22%freshwater from seawater and increasing nitrogen use efficiency by 18%.Achieving daily energy self-sufficiency required 4500 m^(2)photovoltaic panels and 5000 m^(2)solar heating system.While the system model was initially devised with a specific focus on conditions in Israel,it has been designed with scalability,allowing it to be adapted and applied extensively across diverse peri-urban regions and arid zones globally.
