Research On The Evaluation System Of Regional Water-saving Society Based On The Coordinated "Water Resources-Ecological Environment-Economic Society"

Water is the headspring of life and the irreplaceable resources with which people lived. Construction of the water-saving society is the inevitable choice to solve national water problems, coordinate the harmonious development of human being and nature, build a comfortably-off society and carry out the strategies of sustainable development, also it is a strategic initiative to achieve sustainable utilization of water resources. The researches on evaluation of the regional water-saving society plays a very important theoretical and practical meaning of promoting the coordinated and sustainable development of"regional water resources, ecological environment and economic society"and guiding the construction of water-saving society.This paper based on the discussions of the concept, core and connotation of the water-saving society, respectively carried out following researches:(1)Firstly, analyzed"the water resource system, ecological environment system and economic society system", established a combined evaluation system of water-saving society which based on the coordinated"water resources -ecological environment - economic society".(2)By the numbers analyzing of the relationship among various element(sindicator) of the combined system, adopted principal component analysis to reasonably select the various indicators and structured a regional water-saving society evaluation indicator system which based on the coordinated"water resources -ecological environment - economic society".(3)Adopted the Analytic Hierarchy Process(AHP)method to identify the weight of evaluation elements(indicator)of various evaluation levels and use the Comprehensive Index method to evaluate the water-saving society of study area by builting a mathematical model; meanwhile, carried out the sensitivity analysis of the whole evaluation system.(4) Applied Fuzzy Evaluation method to conduct a comparative analysis and verify reliabilities of the evaluation.(5)Carried out the evaluation and subarea-analysis which be aimed at the water-saving society of various counties and districts of study area. And the evaluation is similar to objective reality. (6)Finally, this paper made a forecasting evaluation of the water-saving society of study area in future planed-years.
