Embodiment Construction

[0058] In order to make the technical solutions of the present invention clearer and clearer to those skilled in the art, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0059] like Figure 1-Figure 4 As shown, a kind of ecological environment quality evaluation method based on water ecological benefits provided by the present embodiment comprises the following steps:

[0060] Step S1. Construct ecological indicators through the structure and function of the ecological environment. Since the components of the ecological environment are complex and diverse, it is necessary to select indicators from a clear and reasonable perspective to avoid the phenomenon of index failure or incomplete indicators. The construction of ecological indicators specifically includes the following step:

[0061] Step S1.1, preprocessing the urban remote ...

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, and the method comprises the steps: S1, constructing ecological indexes through the structure and function of an ecological environment; and step S2, multi-index fusion based on entropy. According to the method, the characteristics of the ecological environment in the aspects of structure and function are fully utilized, reasonable ecological indexes are constructed, and particularly, the WBEI can describe the complexity of the ecological environment more accurately through construction and addition of water ecological elements. According to the method, the concept of information entropy is introduced, the interaction relation between the ecological environment and the ecological indexes is clearly revealed, the index weight obtained through the fusion method based on the information entropy is obtained through image information amount calculation, compared with a traditional fusion method, the method is more objective, and interference of subjective factors of people can be avoided.

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...
