Résumé partiel
Water resources are the basis resources for the economic and social development.It with resources of petroleum and food is called three strategic resources. With therapid development of China’s economy and society, the demand of water is increasingrapidly ; the contradiction between supply and demand of water has become one of themost prominent issues in China’s economic growth and environmental protection. Thesame time, water is important factors that affect the ecological balance. The problems ofexcessive use of water resources and soil and water loss become more prominent. Theseproblems in the northwest region is even more prominent, and the water resourcessituation in the northwest region has its own characteristics, such as the quantity ofwater is congenitally deficient, a higher rate of water resources development, the lowerefficiency of water use, excessive development led to the deterioration of waterenvironment, water pollution caused reduced supply, and so on. Face the developmentstatus and opportunities of northwest region ; the development pressure is still huge.Therefore, how to deal with the relationship between environmental, economic andsocial sustainable development, and to promote the efficient use of water, the protectionof environment, and speed up the construction of ecological civilization became socialfocus and research hotspots. This paper is based on the above objective, taking ShanxiProvince as an example, research on the water resources carrying capacity (WRCC) innorthwestern region. Mainly includes :(1)Improve the water circulation mechanism. Breakthrough the amount of waterresources bearing limited, the green water resources and water of environmentalrequirement were into the whole process of water circulation system, realizes thedevelopment of the natural-ecological system. Based on virtual water theory, water resource has into the trade cycle of social and economic system. It realize thedevelopment of social-economy system.(2) Build the static evaluation model of WRCC. Papers by theecological-economic and water resources circulation mechanism as the foundation, onthe basis of the virtual water theory and water footprint, establish a present situation ofWRCC evaluation model ; including its indicators : deficit of the WRCC, economycarrying capacity, social carrying capacity and ecological carrying capacity. By theecological-economic and water resources circulation mechanism as the foundation, onthe background of the rapid industrialization and urbanization, to search and sorting theimpact factors of ecological-environmental system, society, population and economicdevelopment system, establish a relative situation of WRCC evaluation model. Basedon analysis water resources system, ecological-environmental system, society,population and economic development system, and build a multi-objectiveprogramming model of the WRCC exploration to a certain level of social and technicalconditions, the boundary of the WRCC.(3) The construction of WRCC of dynamic analysis framework.
