River health assessment method based on coordinated development degree

Abstract

The invention discloses a river health assessment method based on coordinated development degree. The river health assessment method includes the steps: building a river health assessment index system and determining the weight of each assessment index; building a river health coordinated development degree assessment model and calculating overall ecological integrality health condition indexes, social service function health condition indexes, coordination degree, comprehensive assessment indexes and the coordinated development degree of a river; classifying the coordinated development degree and the comprehensive assessment indexes and comparing the ecological integrality health condition indexes with the social service function health condition indexes to obtain comprehensive assessment results based on the river health coordinated development degree assessment model; analyzing river system health coordinated development conditions. According to the river health assessment method, the overall health degree of the river and the health degree of monitoring points can be reflected, and the coordinated development conditions of the natural attribute and the social attribute of the river can be assessed.

Description

technical field [0001] The invention relates to a method, more specifically, to a river health evaluation method based on coordinated development degree. Background technique [0002] The health problems of river ecosystems are caused by human activities and cannot exist outside of human value judgments. In addition to maintaining the structure and function of the ecosystem, a healthy river must also have certain social value. Therefore, the river health evaluation system should include two aspects of ecological integrity and sustainable social service functions. Ecological integrity represents the health of the natural state of the river and affects the resilience of the ecosystem; sustainable social service function refers to the role of the river in supporting and promoting the development of the social economy and human health, which is the main goal of ecosystem management. Only the coordinated development of the two can maintain the virtuous cycle of the river ecosys...

Problems solved by technology

The traditional river health evaluation method is to synthesize the information of the influencing factors by multiplying the health degree and weight of each influencing factor of the river. Although the comprehensive evaluation result of the river health can be obtained, it is difficult to reflect the comparative relationship between the interaction of the various influencing factors.

In addition, the traditional river health evaluation method has less consideration for social service functions, and the river health index system proposed by it is generally only for specific rivers, and has little reference significance for the health evaluation of other rivers.
