Evaluation index system and evaluation method for comprehensive benefits of water-saving reform of irrigation district

Abstract

The invention discloses an evaluation index system and an evaluation method for comprehensive benefits of water-saving reform of an irrigation district. The method is characterized by comprising the following steps: step a, constructing the evaluation index system by determining five first-grade indexes capable of reflecting the comprehensive benefits of water-saving reform of the irrigation district as a criterion layer and setting twelve second-grade indexes on the basis of the current technical standards and theoretical research results according to an actual project for water-saving reformoptimization of a water transport and distribution system of the irrigation district; step b, determining evaluation standard for the value range of each evolution index according to the evaluation indexes; step c, evaluating the comprehensive benefits of water-saving reform of the irrigation district with a projection pursuit method. The evaluation index system and the evaluation method can evaluate the comprehensive benefits of water-saving reform of the irrigation district comprehensively and wholly, so that the comprehensive benefit level of water-saving reform of certain irrigation district can be reflected objectively and accurately.

Description

technical field [0001] The invention relates to the technical field of evaluation of comprehensive benefits of water-saving transformation of irrigation areas, in particular to an evaluation index system and evaluation method of comprehensive benefits of water-saving transformation of irrigation areas, belonging to the technical field of water conservancy engineering. Background technique [0002] As one of the main resources for human survival and development, water resources are of great importance. The importance of irrigation areas for agricultural water conservancy has also been highlighted. However, most of the irrigation districts in my country were built in the 1950s. After a long period of operation, the irrigation districts generally suffered from serious problems such as damage to field supporting facilities, low rate of anti-seepage lining in canal systems, and backward operation and management systems in irrigation districts, resulting in low irrigation water ut...

Problems solved by technology

However, most of the irrigation districts in my country were built in the 1950s. After a long period of operation, the irrigation districts generally suffered from serious problems such as damage to field supporting facilities, low rate of anti-seepage lining in canal systems, and backward operation and management systems in irrigation districts, resulting in low irrigation water utilization efficiency and construction problems. Low standards, poor operation safety, unsupported projects, poor efficiency, shortage of water resources, insufficient water supply capacity, rigid management system of irrigation areas, etc.
