| With the increasing population and economic, the function of water environmental system has been deteriorating, and the deteriorating water environment has been one of the most serious problems in the world. So, water environmental planning has been drawn international attention. Therefore, in order to determining whether the objects of the regional water planning is suitable or not, we should evaluate it's indicators. Based on the comprehensive analysis of the indicators'suitability of water environment and the selection methods, the Analytic Hierarchy Process (AHP) is used for regional water environmental planning target selection in this paper.This paper combines the theory and the practice of the method. And the basic theory of the water environment and its methods are more systematic research. Based on the status of the water environmental planning at home and abroad, and the study of indicators, the characteristics of the region water environment and influencing factors are analyzed. Constructed by the goal, there are four floors sub-criteria indicators in this planning system. Then, AHP is used for choosing them, by the evaluation weight values. At the level of analysis and fuzzy comprehensive evaluation method, the support of the water environment on the Wuzhong District Planning indicators are appropriate, rational, scientific analysis and evaluation. Based on the impact of water environment systems in Wuzhong District Planning, the water environment indicators have been studied. Finally, the establishment of the COD, BOD5, fresh water, industrial output, the rate of sewage treatment plants etc. will be selected. This analysis method can supply environment-related planning and environmental evaluation as a reference, and can also be used for regional planning departments and environmental management in construction related to water environment, by providing some basis. Key words: Water environmental planning; indicators; AHP; fuzzy evaluation method... |
