Method of optimizing and determining water supply type reservoir dispatching diagram considering human and ecological needs

Abstract

The invention discloses a method of optimizing and determining a water supply type reservoir dispatching diagram considering the human and ecological needs, which comprises the following steps of: firstly determining the minimum ecological water requirement of a river; selecting AAPFD indexes and weighing the disturbing degree of a river hydrological regime; establishing a reservoir dispatching regulation combining the minimum ecological water requirement and a reservoir dispatching curve; then respectively determining a measure method of an ecological benefit target and a social benefit target of reservoir dispatchment; converting the social benefit target and the ecological benefit target to an ecological, social and economic total benefit target by adopting compromise programming; optimizing parameters of the dispatching diagram by adopting a genetic algorithm so as to obtain an optimal dispatching diagram which has the disturbing degree of the hydrological regime in a threshold value range and can enable the ecological, social and economic total benefit to be maximum. The invention can ensure that the operation of a reservoir can not generate fierce degeneration of a river ecological system and enable the comprehensive benefit of society, economy and ecology brought by the operation of the reservoir to be maximized.

Description

technical field [0001] The invention belongs to the fields of water resource protection and water resource management, and relates to a method for optimizing and determining a dispatching diagram of a water supply type reservoir, in particular to a method for optimizing and determining a dispatching diagram of a water supply type reservoir that takes into account human and ecological needs. Background technique [0002] Reservoir scheduling map is the most commonly used tool to guide reservoir operation and scheduling. The formulation of a reasonable reservoir scheduling map can improve the social and economic benefits of the reservoir and effectively protect the river ecosystem. There are two types of methods for formulating reservoir scheduling diagrams: simulation method and optimization method. The simulation method is to select a number of hydrological processes corresponding to the design guarantee rate of water supply or power generation of the reservoir from the hist...
