A method for determining the ecological storage capacity of a reservoir to be built for ecological environment protection

Abstract

The invention relates to an ecological reservoir capacity determination method oriented toward ecological environmental protection and used for a reservoir to be built, and belongs to the technical field of environmental protection and comprehensive utilization of resources. According to the human economic society water demand, ecological environment water demand and natural water supply amount of upstream rivers, beginning and ending time when the reservoir needs to supplement drained water is determined as a water supply duration of the reservoir in one year; insufficient water volumes of different time periods of the water supply duration are calculated and accumulated to obtain the total adjustment reservoir capacity of the reservoir to be built under the natural water supply amount, and the adjustment reservoir capacity is distributed according to the proportion of water demands of the water supply duration of the reservoir; finally an ecological reservoir capacity frequency curve is drawn through calculation of the reservoir capacity of different years, and the ecological reservoir capacity meeting the requirements of design dependability is obtained. The method overcomes the defect that ecological water supply is not taken into consideration in traditional reservoir capacity setting, social resistance confronted with the reservoir to be built in the planning process can be relieved, establishment of an eco-friendly reservoir is facilitated, 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 reservoir to be built facing ecological environment protection, and belongs to the technical field of environmental protection and resource comprehensive utilization. Background technique [0002] Traditional reservoir planning and construction aim 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 ecological flow wi...

Problems solved by technology

At present, in the planning of reservoirs to be built, there is no calculation method for determining the ecological storage capacity, and it is difficult to clarify and coordinate the water volume scheduling of human socio-economic, flood control and ecological goals during reservoir operation
