Central China's past economic development mode with "High Input, High Consumption, High Emission" has greatly impeded the process of it's rising. To break through the bottleneck of resources shortage and the environmental degradation, and rise early, it is necessary for Central China to base on "A Resource-Saving and Environment-Friendly Society" and the principle of sustainable...
The purpose of this document is to communicate an economic vision for Urban Economics. Solving the environmental problems associated with urbanization requires lateral thinking, or rather vertical thinking. Problems abound when considering the environmental challenges of an increasingly urban society. Among these are a decreasing vegetation cover of the soil, water absorption capacity, shade and temperature...
Water is a sort natural resource that can't be replaced. It is also one of the important supports for the sustainable development of society and economy. According to characteristics of urban water resources system, an optimal allocation modal of water resources is built considering coordinative development among multi-objective and regions such as the production, living and ecology. Taking gray theory...
Correct evaluation water resources sustainability of a city or an area is one of the most important way to understand the development potential of it. The paper introduced the concept of social adaptive ability, established a social index system and evaluation method of water resources scarcity, and took Tianjin as a case to evaluate water resources sustainability of it from 1998 to 2006. The results...
Basing on the monitoring data of water quality of LiuJiazhuang section and the analysis results of 4 years, applying fuzzy comprehensive evaluation model, according to LtEnvironmental quality standard for surface waterGt to establish the relevant subjection functions, the quality evaluation of surface water in LiuJiazhuang section is made in this paper. The result shows that the change about the water...
The importance for studying the influences to the environment by tourism activities is noted by more and more people. The researching method changes from the original qualitative description to quantitative description. Taken Shanghai ChongMing Island as an example, the tourism environmental carrying capacity of this island is studied by combining with the its unique island characteristics. The factors...
The conflict of water resources environment becomes the important factors of endangering the peace and stability of regions and restricting the sustainable development of river basin. It becomes one of the important duties for water resources management to mitigate the conflict of water resources for river basin and to promote the negotiation and cooperation between parties. This paper analyzes the...
This paper analyzed the characteristics of Chinese water resources and developed a sustainable utilization evaluation system of water resources. Principal component analysis method was used to carry out the evaluation. The results show there is an obvious negative correlation between water resources endowment and its utilization efficiency, and a positive correlation between utilization efficiency...
The prevalent water problems like quantity shortage, environment pollution and ecological damage restrict urban sustainable development. Unreasonable water utilizing causes conflicts between artificial water cycling system and natural cycling water system, which turns out to be the source of urban water problems. To find ultimate solutions to the water problems and the way of sustainable water utilization,...
The conventional dam-break environmental risk evaluation method is limited to qualitative analysis and the hydraulic factors such as when flood arrive, flood fastest velocity, whole time of flood submerge and flood depth are acquired almost by the method of simplified analysis or empirical formula method. Aimed at these problems exist in dam-break flood environmental risk evaluation, the volume of...
The ecological footprint of Pinggu District in 2001 and 2005 was calculated and comprehensively analyzed. Results showed that the ecological footprint, ecological carrying capacity and ecological deficit in 2001 were 2.1464 hm2/cap, 0.3344 hm2/cap & 1.81204 hm2/cap respectively, and then 3.6172 hm2/cap, 1.8794 hm2/cap & 1.7378 hm2/cap in 2005. By contrast the results of 2001 with 2005's, it...
The water resources vulnerability (WRV) is defined as the characteristics that water resources system easily suffers damage from natural factors or human activities, and it is difficult to recover to its former status once this damage happens. The quantitative assessment of the WRV is important for the scientific decision-making for the sustainable water resources exploitation and utilization. In...
The high tech electronic industries have played a vital role in driving the world economy. In Taiwan, many high-tech parks have been established by either the government or high-tech manufacturers to promote national economic development. However, the manufacturing of high-tech products release hundreds of chemicals and generate thousands of tons of wastewater per day. As the electronic production...
Today, the disproportional distribution of water resources becomes a restrictive factor for sustainable development of Chinese national economy. Therefore, Chinese government has implemented numerous Inter-basin water diversion projects. However they are complicated and systemic engineering projects which consist of many facilities with longer delivery route, involutedly transit area and multitudinous...
The paper discussed the optimum uses of water resource in a city based on social-economic-environmental (SEE) complex system by applying system dynamic model, which fully considered the interactions and interrelations amongst each element in the SEE complex system. The SD model can be used to estimate the overall development trends based on the current development status, and then relevant information...
Based on a series of research works on water environment monitoring and water resources protection in Dongting lake, this paper discusses the strategy of sustainable development about the requirements of water function and protection objectives, and quantitatively analyzes the variation trend of water environmental capacity of major pollutants before and after the running of the three Gorges project...
In sustainability science (SS) it is not only difficult to identify what needs to be solved but how to solve the problems once identified. There has been no consensus on underlying question of ldquowhat is structuring in SS?rdquo This paper focuses on articulating in the form of a reference model a set of required elements, functions, and actions for structuring SS knowledge and on realizing a part...
Sustainable development is widely practiced by many engineers, academicians and policy makers for making the industries environmental friendly, to obtain sustainability in any industry there are many methods. Resources utilized in an industry should be identified properly in various processes and its utilization is to be optimized to increase the environmental performance of the industry. Ecomapping...
Sustainable management of groundwater resources is of crucial importance for regions where freshwater supply is naturally limited. Long-term planning of groundwater usage requires computer-based decision support tools: on the one hand, they must be able to predict the complex system dynamics with sufficient accuracy, on the other, they must allow exploring management scenarios with respect to different...
Watershed, as it comprehensively represents any part of water resource on our land, is considered the most appropriate units not only for the assessment of water environment, analysis and usage of water resources, but also for the management of water quality. Therefore, many scholars use watershed management to deal with the arising water problems and maintain sustainable development at watershed...
