Research on water resources allocation in central Guizhou based on multi-objective optimization

The first stage of the water conservancy project in central Guizhou Province is taken as a research object, and the optimal allocation of water resources is carried out. Based on the analysis of the basic facts of the water conservancy projects in central Guizhou Province and water resources optimal allocation principle, we established the optimal allocation model of water conservancy project for central Guizhou Province, and adopted the multi-objective programming to carry out model analysis. The water resources optimization allocation results of Guizhou Irrigation District, Guiyang City, Anshun City in 2007, 2015 and 2020 were obtained. The comparative analysis on three indicators, the supply and demand balance, economic benefit and sewage discharge, shows that the model can provide scientific and reasonable basis for the water resources allocation in central Guizhou Province.
