Establishment and Application of a Comprehensive Evaluation Model for Management of Water-Saving Irrigation Developing Level Based on Set Pair Analysis - Si Chuan Province as Example

Abstract:

Evaluation of water-saving development level of irrigation management level is an important foundation to make the water-saving and irrigation policy, and improve irrigation management. This paper established a comprehensive evaluation system for the developing level of water-saving and irrigation management after comprehensively analysis of main contents of irrigation management. It include 4 secondary level indicators and 16 third-level indicators, and build a comprehensive evaluation model. Further more, entropy method and gradation analysis method were introduced to calculate the combination weight of each evaluation indices, which enhance the scientific in weight calculation, and a comprehensive evaluating model for irrigation management and water-saving developing level was established on the basis of it. The comprehensive evaluation of irrigation management and water-saving developing for Sichuan Province and 21 other regions was done by this model, and the results are accord with Sichuan Provinces actual situation of the irrigation management and water-saving developing. Therefore, the model of comprehensive evaluation for irrigation management and water-saving development level has a relative strong practicability, which can offer scientific guidance for irrigation management and water-saving development in different regions.
