With the development of urbanization,the original connection between rivers is interrupted,and the hydro-dynamic conditions become worse.Therefore,it leads to water pollution and deterioration of water ecological function.Taking Yinxi Plain as the research object,an evaluation method of water environment improvement effect based on ana-lytic Hierarchy process-entropy weight method was proposed.On the basis of hydrodynamic and water quality parame-ters,economic benefits and sensory parameters are considered comprehensively to evaluate the effectiveness of the water environment improvement program.The improvement in the study area was quantitatively compared,and scheme 3 was finally the best.Compared with the traditional evaluation methods that only consider hydrodynamic,water quality or oth-er single factors,this method can overcome the influence of subjective weight on the evaluation results,evaluate the en-hancement effects of different connectivity schemes more comprehensively,and realize the comprehensive evaluation and optimization of schemes.
