基于SPA和云理论的水资源承载能力评价研究

Evaluation of Water Resources Carrying Capacity Based on Set Pair Analysis and Cloud Theory

我国的水资源短缺问题日趋严重,新形势下,双控行动是解决水资源短缺问题的战略措施,研究水资源承载能力有助于水资源的可持续发展。从水资源总量、水资源强度、生态环境3个方面出发,基于集对分析(SPA)和云理论,构建了水资源承载能力评价体系,确定出评价等级与标准,并以南京市浦口区为例,研究了浦口区的水资源承载能力。结果表明,浦口区2016年的水资源承载能力等级为一般。此结果与实际情况相符,验证了模型的适用性,为最严格水资源管理和水生态文明建设提供了科学依据。

The shortage of water resources in China is becoming more and more serious.Under the new situation,double control action is a strategic measure to solve the shortage of water resources.It is of great significance to study the carrying capacity of water resources for the sustainable development of the society and economy.From the three aspects of total water resources,water resources intensity and ecological environment,based on set pair analysis and cloud theory,the evaluation system of water resources carrying capacity was constructed,and the evaluation grade and standard were determined.The water resources carrying capacity based on the total and intensity of water resources was studied in Pukou District of Nanjing.The results show that for Pukou area in 2016,the resource carrying capacity grade is general,the result coincides with the actual situation,which validates the applicability of the model,and provides a scientific basis for the most stringent water resources management and water ecological civilization construction.
