Study On Water Environment Security

The shortage of water resources is the point at a lot of contradictions of the conception of sustainable development on 21th century. It is very serious in Shandong Province, and a mass of industrial and sanitary wastewater discharged into water environment has led to serious water pollution and harmed the ecological environment. And it has been the most impedimental factor in building of ecological Shandong province.Based on the position, this thesis puts forward the concept of Environment Security (ES) and Water Environment Security (WES) from Environment Security and probing to how to evaluate and forecast it.At first, ES and WES are put forward and explained. WES means that with the development of society, the development of production is leading to the breakage of water circulatory system and decay of water function, which brings on a series of troublesome problem in economy, society and environment. After presenting the basic connotations of index system for Sustainable Development, Circular Economy, Systematic Project and Bearing Capacity, the dissertation establishes the index system for WES based on theory of Fuzzy mathematics. The system consists of water resource, social system and ecology system. Proportions are put by average square difference method and WES is evaluated by general index. And the development trends of WES is forecasted by model GM(1,1).On the basis of above, the thesis evaluates the actuality and history of WES in Shandong, and forecasts the development trends of WES in building of ecological Shandong province. Condition of water resources, water supply potential, water environment, natural disaster, and ecological safety have profound effect on WES. Moreover, Agricultural water consume efficiency, rural non-point pollution, industrialwastewater and household wastewater determinately impact development trends of WES.Contraposing to the evaluation and forecasts results and the problems while people utilizing resource in Shandong, some advice are drawn to ensure water environment utilizing security in building of ecological Shandong province in view of technique means, law measure, management system, emergency monitoring, public consciousness and policy lead.
