Quality Evaluation of Ecological Restoration of Urban Water Pollution based on Analytic Hierarchy Process

Abstract

Ye, Q.Q., 2020. Quality evaluation of ecological restoration of urban water pollution based on analytic hierarchy process. In: Guido Aldana, P.A. and Kantamaneni, K. (eds.), Advances in Water Resources, Coastal Management, and Marine Science Technology. Journal of Coastal Research, Special Issue No. 104, pp. 10–13. Coconut Creek (Florida), ISSN 0749-0208.In view of the problem that the traditional methods cannot comprehensively select the indicators of urban water pollution ecological restoration, which leads to the inaccurate evaluation results of urban water pollution ecological restoration quality, this paper proposes the quality evaluation of urban water pollution ecological restoration based on AHP. Based on the analysis of the current situation of urban water pollution, the comprehensive evaluation index system of urban water pollution ecological restoration effect is constructed based on the multi quantitative method of AHP, and different types of urban water pollution ecological restoration indicators are obtained. The comprehensive evaluation model of AHP is given, the judgment matrix is constructed, and the weight of evaluation index is determined by single ranking of different levels. The fuzzy comprehensive evaluation standard of urban water pollution ecological restoration quality is designed to complete the evaluation of urban water pollution ecological restoration quality. Taking the water pollution ecological restoration of a city as an example, the analytic hierarchy process (AHP) is used to evaluate the quality of water pollution ecological restoration. The weight of different indicators on the ecological restoration of water pollution can be accurately obtained, and the accurate evaluation results of urban water pollution ecological restoration quality can be obtained.
