Water ecological civilization construction is a new concept in the field of water resources,is also an important response of water conservancy industry facing the great situation of national ecological civilization construction.It is one of the most profound institutional changes in the history of water manageme1 nt in our country,and it received serious attention by the government.Water ecological civilization development,realizes the person and water in harmony,is the necessary foundation of urban civilization and the important symbol Water ecological civilization is the core part of ecological civilization.Water plays an important role in ecological development,and the level of water ecological civilization directly affects the whole process of ecological civilization construction.The key point is to evaluate the water ecological civilized urban construction in QuZhou,followed the principles of integrity,guidance,dynamics,data accessibility and the combination of representability and independence,an evaluation index system of national water ecological civilized urban construction in QuZhou is builded up.by means of system analysis,theoretical analysis,frequency statistics,expert consultation and independent analysis and test,the water safety,water environment,water ecology and water management,and the water ecological civilization index layer of 16 first-level indicators were determined.Through the comparison of several methods,finally determined the weight of each index by using the method of analytic hierarchy process and fuzzy clustering cyclic iterative method,and constructed the evaluation model of urban construction level of water ecological civilization,and divided Quzhou City water ecological civilization urban construction evaluation into four grades: "excellent,good,middle and poor".Index data of that various index of Quzhou City in 2017,based on the analytic hierarchy analysis and fuzzy cluster cycle iteration method,the assessment score of the evaluation of ecological city construction evaluation of Quzhou City water is 89.53 and 89.60 respectively,the two evaluation result are very close.According to the evaluation results,the evaluation indexes of water safety and water environment in the criterion layer index are all in the "excellent" level,and the evaluation index of water ecology and water management is in the "good" level.The result of the construction of the water ecological civilization in quzhou is significant,and the level of "excellent" is about to be entered,and the degree of realization of most indicators is about to reach the target value.The evaluation result is more objective and comprehensive,which reflects the current situation of the urban construction of water ecological civilization in the city,and proposes Suggestions for the weak links in the evaluation,which provides scientific basis for better urban construction of water ecological civilization in the later stage,and provides decision-making reference for government departments.
