To recognize the state trend of regional water resources carrying capacity and its key influence indicators,this paper adopts the game theory to determine the combined weight of the evaluation indicators.The five-variable gravitation subtraction set pair potential is introduced to judge the trend and identify the key indicators.The dynamic evaluation method of regional water resources carrying capacity based on the game theory and the five-variable gravitation subtraction set pair potential is established and applied to Guangdong Province.The results show that the water resources carrying capacity of Guangdong Province is generally good and developing well from 2013 to 2019.It fluctuates downward in 2014 and 2017.The five-variable gravitation subtraction set pair potential identifies the key indicators,including the water resources per unit area,the proportion of environmental protection investment in GDP,urbanization rate,and the industrial water consumption per ten thousand yuan output.The evaluation method of regional water resources carrying capacity based on five-variable gravitation subtraction set pair potential is easy to conduct and is readable,which can provide a new method for dynamic evaluation of water resources carrying capacity. |
