Assessment of Relative Water Resources Carrying Capacity and Sustainable Development in Chengdu,China

Abstract

Water shortage has become an important factor restricting the sustainable development of cities. This paper adopts the research ideas and methods of relative resource carrying capacity, and uses China's national and Chongqing as reference areas to evaluate the relative water resources carrying capacity, the relative economic resource carrying capacity and the synthetic carrying capacity of Chengdu from 2000 to 2015, and analyzes Chengdu's carrying capacity of water resources relative to population and economy. Using the same method, the resource carrying capacity of each district and county in Chengdu from 2000 to 2015 was evaluated, and the spatial distribution of water resources in various districts and counties was analyzed. The research shows that compared with China's national and Chongqing, the relative water resources carrying capacity of Chengdu has been overloaded for nearly 10 years. To a certain extent, this reflects that Chengdu's economic growth is not compatible with the carrying capacity of water resources, and the existing economic growth model is constantly weakening the capacity of resources. In addition, there are still problems in the imbalance of water resources and economic development in various districts and counties in Chengdu. The water resources carrying capacity in the eastern region has been seriously overloaded, with the central city being in the most severe area, and the water resources in the western region have yet to be further developed and utilized. The research results provide a reference for the grim situation faced by the government in controlling the water resources carrying capacity of Chengdu.Therefore, in order to achieve sustainable development in Chengdu, it is necessary to deal with the coordinated development of population, water resources and social economy.
