Abstract

Reveal the state of water resources carrying capacity in Shaanxi Province, and provide thought guidance and theoretical support for enhancing the carrying capacity of water resources in various regions of Shaanxi Province. Taking Shaanxi Province as the research object, considering four dimensions of water resources, society, economy and ecological environment, we establish the evaluation index system of water resources carrying capacity, utilize the method of “entropy weight - coefficient of variation” to get the weights of each index layer, and use the TOPSIS model to get the comprehensive evaluation index of water resources carrying capacity, and then carry out the characterization of the time series and spatial distribution of the index. The results show that (1) the water resources carrying capacity index of Shaanxi Province increased steadily from 0.3933 to 0.4616 during the 10-year period from 2011 to 2020, and the carrying capacity class gradually changed from the stage of mild overload to the stage of endangered overload; (2) spatially, the water resources carrying capacity from the north and the south differed much from each other and changed to the enhancement of each region of Shaanxi Province, with a decrease in the discrepancy.
