Abstract

Xie, C.; Cao, J.; Chao, L., and Li, Y., 2020. Study on comprehensive assessment of water-resource safety based on improved TOPSIS coupled with GA-BP. In: Hu, C. and Cai, M.

The water-resources security evaluation index system is constructed from the coupling system of water resources–economic society–ecological environment. The absolute ideal point and the I-FAHP–improved constant TOPSIS method were used to avoid the reverse defect caused by the ideal solution and its weight change, so the comprehensive evaluation model of water-resources security based on the improved TOPSIS method was established. Finally, the improved TOPSIS and GA-BP neural network were effectively combined for training and testing. This evaluation model is applied to grade the water-resource security state of Hunan province from 2016 to 2019.The results show that the water-resource security in Hunan province from 2016 to 2019 is in a relatively stable state on the whole, belonging to the range of relatively safe state and critical safety state, and the level of safety state presents a trend of steady rise.
