River regulation water demand determination method based on ecological water demand calculation

Abstract

The invention relates to a river regulation water demand determination method based on ecological water demand calculation. When the water demand is determined according to the determination method, the ecological target of a regulation project is clearly put forward by combining a regulation project target according to natural and hydrological conditions of a regulated river section, and the river water demand is divided into flow type water demand and consumption type water demand according to different properties of the river water demand. According to the method, the target demand of the river regulation project is taken into consideration in calculation, and the repeated calculation process is reduced, thereby being capable of providing an accurate water volume basis for planning an implementation scheme and a later-period water supplementing scheme for the project, and being capable performing simple calculation and determination on the river water demand for ensuring the river regulation effect in allusion to different hydrological conditions and different regulation targets.

Description

technical field [0001] The present invention relates to the field of river management, in particular to a method for determining the water demand of a river in a river management project, in particular to a method for determining the water demand for river management based on the calculation of ecological water demand, so as to ensure the health and ecology of the river after the implementation of the river management project Stablize. Background technique [0002] Under the background of climate change and human activities, due to the irrational development and utilization of water resources, wetland ecosystems such as rivers, lakes, and estuaries are in short supply of water, and a large number of rivers have been cut off and degraded, and the problem of ecological degradation is becoming more and more serious. . In recent years, ecological management and restoration of rivers have been started in some areas. In this process, in order to keep the restored rivers in a heal...

Problems solved by technology

[0005] The purpose of the present invention is under the background of the sustainable operation of the river ecological system that focuses on water conservancy and flood control in the current river channel management project, and aims at the problems that the water supply to the river cannot fully meet the ecological needs of the river in the river channel management project, and the treatment project cannot achieve the expected effect. A simple method for determining the water demand for river channel management based on ecological water demand calculation that can guarantee the effect of river channel management for different hydrological conditions and different governance objectives
