基于综合集成赋权法的灌区发展状况综合评价OA

As irrigation districts serve as the core support for agricultural production,food security,and ecological civilization construction in China,scientifically evaluating their development status is the key to optimizing management strategies and enhancing operational efficiency.At present,in the evaluation of irrigation districts,single weighting methods have obvious limitations.Subjective weighting methods are easily influenced by human experience biases,while objective weighting methods often fail to reflect actual management needs.This leads to unreasonable index weights,thus making the evaluation results lack pertinence.This paper focuses on the core issue of"how to construct a comprehensive evaluation system for irrigation districts that takes into account both subjective and objective factors",and proposes a comprehensive integration weighting method.By re-weighting the weights determined by the Analytic Hierarchy Process(subjective)and the Coefficient of Variation method(objective),the relative importance of the subjective and objective weights can be quantified,thereby enhancing the scientific nature of the index weights.Using 9 medium-sized irrigation districts in Changji Prefecture,Xinjiang as the research objects,an evaluation index system comprising 12 indicators was constructed from four dimensions:water usage,engineering facilities,management level,and production efficiency,and the evaluation results were compared and verified by combining the grey correlation method and the approximate ideal point method.The results show that the three methods are basically consistent in evaluation ranking,and the comprehensive integration weighting method can more accurately reflect the differences in the multi-dimensional development of irrigation districts,providing a clear direction for identifying their shortcomings.
