Research on Water Resources Shortage Degree of Gansu Province Based on Comprehensive Score Method and TOPSIS Model with Entropy Weight Method
In order to explore the water scarcity situation of inland river basin,Yellow River Basin and Yangtze River Basin in Gansu Prov-ince,the comprehensive scoring method and entropy weight TOPSIS model were used to quantitatively analyze the water scarcity degree of the three major river basins during 2011-2022.The results show that the comprehensive score of water resources shortage degree of the three ma-jor river basins is between 12.42 and 29.41 and all of them belong to water-scarce basins.The water shortage degree from high to low is the inland river basin,the Yellow River Basin and the Yangtze River Basin.The degree of water resources shortage in Gansu Province is increas-ing in general,showing that water resources are increasingly scarce.Cultivated land rate,irrigation rate,industrial value module,water re-sources utilization rate and current water shortage rate are the main factors influencing the evaluation results.It is suggested that Gansu Prov-ince should improve the construction of water conservancy infrastructure,adjust the industrial structure and strengthen the building of water-saving society to alleviate the shortage of water resources.
