Abstract

The invention discloses an ecological flow quantification method based on an ecology-habitat-flow grouping response mechanism, and relates to the technical field of river ecological environment, and the method comprises the steps: collecting needed ecological data; studying the response relation between the flow process and the fish ecological process through key habitat habitat factors involved in the flow process and the fish ecological process, and disclosing an ecology-habitat-flow grouping response mechanism; and researching the influence effect between the fish ecological process and habitat factors, and determining environment flow components, dynamic optimal habitats, suitability hydraulic parameters and water environment quality constraints under different space-time modules of the fish ecological process. According to the quantification method, fishes serve as a protection target, based on the habitat simulation theory, the response relation between the flow process and the fish ecological process is studied through key habitat habitat factors involved in the flow process and the fish ecological process, and an ecology-habitat-flow grouping response mechanism is disclosed.

Description

technical field [0001] The invention relates to the technical field of river ecological environment, in particular to an ecological flow quantification method based on an ecology-habitat-flow grouping response mechanism. Background technique [0002] Although water resources are renewable, they are limited to a certain extent. With the increasingly prominent problems of river ecosystem destruction and river physical habitat degradation, people have gradually realized the importance of coexistence of river development and protection, and their awareness of ecological protection has gradually strengthened. Ecological civilization and ecological protection have become a global discourse. Strengthening water ecological protection and promoting the sustainable use of water resources are particularly important for building a modernization where man and nature live in harmony. In areas with a high rate of water resources development and utilization, the production and domestic wat...
