Quantitative Study on Beneficial Coefficients of Water Resources Optimal Distribution Model

摘要

It is difficult to quantify some beneficial coefficients in the water resources optimal distribution model. However, this research is a combination of qualitative and quantitative analysis. A judgment matrix is constructed by adopting the scales of index at the first step. Then the relative importance of various factors are determined by making a comparison between factors two by two, and the total order of the relative importance of the factors is established by consolidating human judgment. Finally, experiential judgment of policy decider is quantified, and beneficial coefficients are calculated and determined by the normalization. In this paper, through optimizing distribution analysis of water resources in the Dongshan mining district of the Taiyuan city, the optimal result is following. From the Guanmengqian well field, 15 000 m~3/d of water is sent to the railway bureau and 5 000 m~3/d to the Taiyuan city. From the Zaogou well field, 75 000 m~3/d of water is sent to the Taiyuan city. From mine water inrush, 5 000 m~3/d of water is sent to the power plant, and 1 000 m~3/d to the coal mine district. From mine drainage, 4 000 m~3/d of water is sent to the mine district.
