Study On Comprehensive Evaluation Of Water Resources Carrying Capacity

On the basis of domestic and international studies on the water resources carrying capacity, Leading fuzzy analysis of unquantitative decision-making unit system theories into analytic hierarchy process method(AHP)——Fuzzy Analytic Hierarchy Process(FAHP), it can avoid the weakness of subjective and difficult in judgment matrix's consistency of AHP. Meanwhile, by putting the two methods together, it is no use to calculate complicated total degree of membership using fuzzy identification and optimization models.This thesis used FAHP to study the regional water resources carrying capacity. On the basis of analyzing function mechanism among sub-systems, target variables, decision-making variables and their functions among those variables were given. It takes the Bortala River Basin and JinRiver Basin as an example, the comprehensive evaluation index system of the regional water resources carrying capacity is constructed under the theory of Fuzzy Analytic Hierarchy Process (FAHP). By means of the Delphi Expert Investigating Process,the paper uses the FAHP in solving index weighting of water resources carrying capacity and details the appraising factors, the appraising concrete process and the application method. Then developmental directions of water resources carrying capacity were forecasted in the future.According to the result of research, it is feasible to analysis water resources carrying capacity in Bortala River Basin and JinRiver Basin by using FAHP. In light with the comprehensive evaluation of the water resources carrying capacity in research area, the regional social economy development planning, the decision-making regulation of the water distribution, the methods and approaches to enhance the water resources carrying capacity were laid out. This has offered certain reference and suggestion for the sustainable utilization research of regional water resources and sustainable development of society.
