改进TOPSIS方法在水资源分配中的应用研究

s the source of life on which human beings depend for their survival, water resources occupy an important position in the country\'s economic development. With the sharp decline in the existing water volume in China, how to rationally allocate water resources in various regions and avoid the occurrence of social contradictions have become urgent problems to be solved. In this paper, by analyzing the current situation of water resources in Hebei Province, the TOPSIS method is superior to the conventional method, and the "vertical distance" is used instead of the "European distance" for calculation. From the supply and demand aspects, seven indicators such as groundwater storage, ecological water consumption and industrial water consumption were selected to obtain the water resource allocation of four cities in 2021, and the calculation results of the conventional TOPSIS method were compared, which proved that the method met the principles of optimal allocation of urban water resources and fairness and efficiency.??
