Abstract

The invention discloses an urban multi-reservoir water source water distribution method based on comprehensive evaluation information, which relates to the technical field of water resource planning and allocation. At first, a multi-reservoir water source comprehensive evaluation system is constructed, the evaluation factors of four evaluation subsystems are determined, and calculate the comprehensive water quality value of the water quality target subsystem. The comprehensive operation value of the operation subsystem and the comprehensive evaluation value of the multi-reservoir water supplysystem are used to determine the sequence of the multi-reservoir water supply and the actual water supply quantity. The principal component analysis method is used to objectively select the evaluationfactors that affect the water quality objectives when selecting the water quality evaluation factors. The comprehensive evaluation method and fuzzy evaluation method are used to calculate the comprehensive water quality value of the water quality objective subsystem and the comprehensive operation value of the operation subsystem respectively. The method of multi-reservoir water supply allocationbased on comprehensive evaluation value can reduce the influence of human subjective factors and provide scientific basis for the sequence of multi-reservoir water supply and actual water supply.

Description

technical field [0001] The invention relates to the technical field of water resource planning and configuration, in particular to a method for allocating water volumes of urban multi-reservoir water sources based on comprehensive evaluation information. Background technique [0002] When the quantity, quality, temporal and spatial distribution characteristics, development conditions, utilization status and supply and demand development trend of existing urban water resources are determined, objectively, scientifically and systematically evaluate urban water supply sources, and reasonably determine the water supply of urban water supply sources The proportion is of great significance for guiding the development, utilization and planning management of urban water resources. [0003] At present, domestic and foreign studies on multi-reservoir water source evaluation mainly include system dynamics method, projection pursuit method, fuzzy evaluation method, support vector machin...
