A method for evaluating ecological environment quality based on water ecological benefits

Abstract

The invention discloses an ecological environment quality evaluation method based on water ecological benefits, and relates to the technical field of ecological environment quality evaluation, including step S1, constructing an ecological index through the structure and function of the ecological environment; step S2, multi-indicator fusion based on entropy; The invention makes full use of the characteristics of the ecological environment in terms of structure and function, and constructs reasonable ecological indicators, especially the construction and addition of water ecological elements, so that WBEI can more accurately describe the complexity of the ecological environment. By introducing the concept of information entropy, the interaction relationship between the ecological environment and ecological indicators is clearly revealed, and because the index weight obtained by the fusion method based on information entropy is obtained by calculating the amount of image information, compared with the traditional fusion method It is more objective and can avoid the interference of human subjective factors.

Description

technical field [0001] The invention relates to an ecological environment quality evaluation method based on water ecological benefits, and belongs to the technical field of ecological environment quality evaluation. Background technique [0002] With the intensification of global resource and environmental problems, governments all over the world attach great importance to the study of ecological environment. Especially in developing countries, the contradiction between the rapid urban development and the fragile ecological environment is becoming increasingly acute under the urgent development requirements. The ecological environment is a complex community formed by various ecological factors interacting and restricting each other through material exchange, energy flow and information transmission. In order to realize the coordinated development of the city and the ecological environment, accurate evaluation of the quality of the ecological environment has become an impor...

Problems solved by technology

When there are many and complex ecological indicators, it is easy to cause the problem of index failure. Therefore, how to select effective indicators to clearly represent the complex ecological environment is still one of the difficulties.
