Construction method of drainage basin water system collaborative bearing capacity evaluation model

Abstract

The invention provides a construction method of a drainage basin water system collaborative bearing capacity evaluation model. The construction method includes the steps: based on water system bearingcapacity research literature, evaluation standards and an expert database, screening indexes related to water resources, water environments and water ecology, and constructing a collaborative bearingcapacity evaluation index system; based on the structural equation model, calculating the weight of each index in each subsystem; based on the weight of each index, calculating the bearing capacity index of each subsystem; carrying out weight assignment on the bearing capacity index of each subsystem by adopting an analytic hierarchy process in combination with basin characteristics; according tothe bearing capacity index of each subsystem and the weight corresponding to the bearing capacity index of each subsystem, obtaining the coupling synergy degree among the subsystems, and constructinga water system collaborative bearing capacity evaluation model based on the synergy degree; and realizing the evaluation of the collaborative bearing capacity of the water system. Therefore, the complexity of a water problem can be embodied, and the diversity of social economic development on water requirements can be embodied, and finally a reasonable, scientific and accurate water system bearing capacity red line is marked.

Description

technical field [0001] The invention relates to the technical field of evaluation of water resources carrying capacity, in particular to a method for constructing an evaluation model of collaborative carrying capacity of a river basin water system. Background technique [0002] Water resources carrying capacity is a concept of carrying capacity applied in the field of water resources. The "water resources carrying capacity" was first proposed in the late 1980s by the soft science project of water resources, and strives to solve the increasingly scarce water resources and the growing water shortage in Xinjiang. conflict between needs. Facing the increasingly severe ecological environment situation, the research on water resource carrying capacity has become the focus and hot spot in the current water science research. [0003] Based on different research purposes, the definition of water resources carrying capacity has different emphases. The existing definitions of water r...

Problems solved by technology

Obviously, it is no longer possible to delineate the red line of carrying capacity comprehensively, comprehensively, scientifically and accurately by only using a single water resource carrying capacity, environmental carrying capacity and ecological carrying capacity.

[0005] To sum up, the existing theoretical system of carrying capacity can no longer adapt to the current complex and multi-level ecological environmental problems, and it is urgent to explore a new theoretical system to solve the bottleneck of the development of social economy and ecological civilization; It can reflect the complexity of the current water problems and the diversity of social and economic development's water demands, and finally draw a reasonable, scientific and accurate red line for the carrying capacity of the water system
