Drainage basin ecological scheduling method based on two-layer structure

Abstract

The invention discloses a drainage basin ecological scheduling method based on a two-layer structure, and the method comprises the following steps: S1, building a target region water volume allocationgeneral control model, i.e., a first-layer structure, according to a water demand, a water conservancy project, climate data, unconventional water source utilization data, underground water development data and underlying surface data; S2, adjusting the discharge flow of the water conservancy project according to the ecological water and the reservoir capacity requirement of the water conservancyproject, and then a water conservancy project ecological scheduling model, namely a second-layer structure, is established; and S3, taking the water quantity allocation quantity and the water quantity balance of the first-layer structure as constraint conditions, taking the maximum water supply quantity in the second-layer structure as a target function of drainage basin ecological scheduling, and obtaining a drainage basin ecological scheduling scheme by adopting a particle swarm algorithm. The method is beneficial to control of water resources by the water conservancy project, the comprehensive utilization efficiency of the basin water resources is conveniently improved, and then the economic benefits and ecological benefits of the water conservancy project are improved.

Description

technical field [0001] The invention relates to the field of watershed ecological scheduling, in particular to a watershed ecological scheduling method based on a two-layer structure. Background technique [0002] Water conservancy projects affect the exchange and recharge relationship between surface water and groundwater. The water conservancy project recharges the groundwater and the groundwater level rises, and salinization is prone to occur near the project; in the downstream area far away from the project, due to the reduction of river runoff, the original wetland and lake area decrease or even disappear; at the same time, it also affects the life, production and Ecological water. The variation of water temperature deteriorates the water quality, affects the amount of dissolved oxygen and suspended solids contained in the water, thus affecting the life cycle, reproduction and reproduction of aquatic organisms, and the water used for human life and industrial and agric...
