Reservoir ecological scheduling method giving consideration to Chinese sturgeon reproductive demands

Abstract

The invention relates to a reservoir scheduling method, in particular to a reservoir ecological scheduling method giving consideration to Chinese sturgeon reproductive demands. The method aims at a spawning period (from October to November) of Chinese sturgeons, takes Chinese sturgeon spawning field spawning fitness as a reservoir ecological benefit evaluation index, combines water conservancy project socioeconomic benefit target in the period, establishes a reservoir ecological scheduling model on the basis of satisfying flood control benefits, shipping benefits, and water resource utilization benefits and takes power generation benefits and ecological benefits as a bi-target, and uses a progressive optimization algorithm (POA) and a compound type optimization method to conduct model solving, thereby achieving a reservoir ecological scheduling process with the largest comprehensive benefits. The reservoir ecological scheduling method giving consideration to the Chinese sturgeon reproductive demands can effectively protect Chinese sturgeon resources and give full play to economic benefits at the same time so as to achieve comprehensive benefit maximization.

Description

technical field [0001] The invention relates to a reservoir regulation method, in particular to a reservoir ecological regulation method that takes into account the reproductive needs of Chinese sturgeon. Background technique [0002] The Chinese sturgeon is a large anadromous fish, and its parent fish enter rivers from the ocean for reproductive migration from April to June every year. The Chinese sturgeon is mainly distributed in the main stream of the Yangtze River, and the breeding season is generally from early October to mid-November. Since the 1980s, affected by factors such as dam obstruction, water quality, shipping, and stagnant temperature in reservoirs, the population of Chinese sturgeon has declined sharply and is in an endangered state. It was listed as a Class I protected animal in my country in 1988. The operation of water conservancy projects in the upper reaches of the Yangtze River has changed the hydrological and hydrodynamic environment of the only rema...

Problems solved by technology

Although this method can meet the needs of the ecosystem to the greatest extent, it weakens the original goal of reservoir construction and makes the reservoir lose its due social and economic functions. At present, it is only discussed in theory, and it is difficult to use it in practice.
