Water resources carrying capacity evaluation and diagnosis based on the two-stage subtraction set pair potential
摘要
Abstract
The evaluation of water resources carrying capacity(WRCC)is essential for identifying re-gional water resources carrying risks and supporting differentiated management.To improve the character-ization performance of set pair potential,this study proposes a two-stage subtraction set pair potential method(TSSPP),which dynamically adjusts the transformation ratio of difference degree to deterministic information according to the relative magnitudes of uniformity and opposition.Then,a regional water re-sources carrying capacity evaluation and diagnosis model was constructed to study the Jianghuai hilly area of Anhui Province.The results show that the regional WRCC generally remained at a critically overloaded level from 2011 to 2022,with significant spatial heterogeneity.The comprehensive carrying capacity fol-lowed the order of Anqing City,Lu'an City,Chuzhou City,and Hefei City from high to low.The evolu-tion of carrying capacity was mainly driven by the carrying pressure and support subsystems,with per ca-pita daily domestic water consumption,water yield modulus,per capita water resources,vegetation cov-erage,and ecological water use rate identified as the main obstacle factors.Compared with the average set pair potential method,TSSPP maintained consistency in the overall trend while effectively improving sensitivity to carrying-state fluctuations and grade categorization.The proposed method provides a scientif-ic basis for allocation optimization and sustainable development of regional water resources.关键词
