City water environment carrying capacity grade evaluation algorithm based on grey clustering analysis

Abstract

The invention discloses a city water environment carrying capacity grade evaluation algorithm based on the grey clustering analysis. Thus, a more visual evaluation can be directly provided for the grade of the water environment carrying capacity in an area, and a scientific basis is provided for scientifically formulating water environment protection and management decisions in the area. The Delphi expert consultation method is used for determining a water environment bearing force evaluation index system, then an order relation analytical method is used for determining the weights of evaluation indexes, and finally the evaluation indexes of the water environment carrying capacity are divided into four grades by combining with practical conditions and the grey weighing and clustering analysis method is used for determining the grade of the water environment bearing force of the certain area. It is proved by experiments results that the city water environment carrying capacity grade evaluation algorithm based on the grey clustering analysis conforms to the objective practical conditions of the city water environment carrying capacity.

Description

technical field [0001] The invention belongs to comprehensive evaluation research, and in particular relates to a grade evaluation algorithm of urban water environment carrying capacity based on gray cluster analysis. Background technique [0002] At present, the trend of water shortage and deterioration of water environment has not been effectively controlled, and has become a key factor restricting the sustainable development of my country's economy and society. Therefore, people have to consider the problem of the coordinated development of the water environment and the human economy and society. On the basis of a deeper understanding of the relationship between the sustainable development of the economy and society and the water environment, the concept of water environment carrying capacity is proposed, which is used to indicate The degree of coordinated development between water environment and economy and society. Research on the regional water environment carrying c...
