Multi-target water resource allocation scheme comprehensive evaluation method

Abstract

The invention relates to a multi-target water resource allocation scheme comprehensive evaluation method. The method comprises the following specific steps: step 1, constructing a multi-target water resource allocation scheme evaluation index system; 2, forming a single evaluation method library; step 3, obtaining evaluation values and evaluation sequences under different single evaluation methods; step 4, Spearman grade correlation coefficient test is carried out on a single evaluation result; step 5, obtaining evaluation values and evaluation sequences under different combined evaluation methods; step 6, Spearman grade correlation coefficient test is carried out on the combination evaluation result, whether a termination condition is met is judged, and if yes, an optimal water resource allocation scheme is output; otherwise, regarding the result obtained by each combined evaluation method as the result obtained by the single evaluation method, and turning to the step 5 for continuous evaluation. According to the method, the problems that in the multi-target water resource allocation scheme evaluation process, the evaluation result of a single method is difficult to compete, and the evaluation results of different methods are different are solved.

Description

technical field [0001] The present application relates to the field of efficient utilization of water resources, in particular to a comprehensive evaluation method for a multi-objective water resource allocation scheme. Background technique [0002] Water resources are the main components of the water resources ecological economic system with water activities as the main body. There are many contradictions in this complex giant system, among which the most fundamental contradiction is the contradiction between the unlimited demand of social and economic growth and the limited supply of natural resources. As one of the effective ways to solve this contradiction, the optimal distribution of water resources has strengthened the unified planning and management of water resources, so that the limited water resources can be fully and effectively utilized. Under the circumstance of water shortage, the reasons such as insufficient water quantity, water quality that does not meet wa...
