Abstract
The carrying capacity of water resources and the environment has become a restrictive factor in economic development. It is also of great significance to Xi’an City, which is rapidly developing and lacking water. Based on the carrying capacity of water resources and environment, we construct an evaluation index system in four aspects: water resources, water environment, society, and economy. The entropy weight method is used to objectively give weights along with the TOPSIS method and the fuzzy comprehensive evaluation method to evaluate the method for the period from 2006 to 2020. The carrying capacity of water resources and the environment in Xi’an City, and its restrictive factors are explored with the obstacle degree model. In general, from 2006 to 2020, the carrying capacity of water resources and the environment in Xi’an showed a fluctuating upward trend. From the perspective of each subsystem, the comprehensive score of each subsystem showed an upward trend. From the perspective of obstacles, the water resources in Xi’an were restricted. The obstacles to environmental carrying capacity mainly came from water resources and water environment subsystems.
