Embodiment Construction

[0043] The method for determining the ecological storage capacity of a single water supply reservoir facing environmental protection proposed by the present invention, its flow chart is as follows figure 1 As shown, the schematic diagram of the optimal model for ecological water dispatching of water supply reservoirs is shown in figure 2 as shown, figure 2 Among them, 1 is the river, 2 is the channel, 3 is the confluence branch, 4 is the reservoir, 5 is the confluence node, 6 is the ecological control section, 7 is the agricultural water in the water supply area, and 8 is the industrial, urban and domestic water in the water supply area. The method includes the following steps:

[0044] (1) According to the requirements of the river management department (or calculate the minimum ecological flow of the river by using the method of hydrology and hydraulics, generally 10% of the average annual runoff), determine the ecological water demand of the ecological control section of...

Abstract

The invention relates to an environmental-protection-oriented ecological reservoir capacity determination method for a single water supply reservoir, and belongs to the technical field of environmental protection and comprehensive utilization of resources. Firstly, according to river ecological flow requirements regulated by a river management department, optimization objectives of a reservoir ecological water utilization schedule are determined, optimization variables and constraint conditions are combined, a reservoir ecological water utilization schedule optimization model is established, a weight set with multiple objectives is constructed, and the multiple objectives are simplified to a single objective for solving; secondly, an optimal water supply scheme is determined according to analysis of the economic society and ecology water lacking rate; at last, the ecological reservoir capacity is calculated according to optimized economic society and ecology water supply output. The method overcomes the defect that ecological water supply is not taken into consideration in traditional water supply reservoir capacity setting and meets the demands of reservoirs for ecological water utilization scheduling in the future; the result is figured out according to the optimization model, more reasonable reservoir capacity can be obtained, and the method has the advantages of being clear in theoretical significance, high in maneuverability and easy to apply practically.

Description

technical field [0001] The invention relates to a method for determining the ecological storage capacity of a single water supply reservoir facing environmental protection, and belongs to the technical field of environmental protection and resource comprehensive utilization. Background technique [0002] The operation and dispatch of traditional reservoirs are all aimed at maximizing social and economic functions such as flood control, water supply, and power generation. The regulation and use of these reservoirs has changed the natural process and law of river hydrology, affecting the habitat and survival of aquatic organisms such as fish, and posing a threat to the river ecosystem. With the increasingly prominent problems of the ecological environment, water demand for the ecological environment of rivers has become an increasingly important task in reservoir regulation. Some scholars have proposed the concept of ecological regulation (Dong Zheren, 2007), and combined ecol...
