- Abstract
Since the beginning of the 21st century, the process of urbanization has accelerated, and water resources have faced greater pressure due to economic and social development and human production activities. In this study, a comprehensive evaluation system of WRCC was constructed by selecting 17 indicators, and the evaluation and analysis of the WRCC of Guangzhou from 2011 to 2020 were carried out based on the TOPSIS method and the obstacle degree model. The results show that the WRCC of Guangzhou showed a downward trend from 2011 to 2015, and gradually recovered from 2016 to 2020. The main obstacle factors for individual indicators are water resources per capita, irrigation water consumption per unit area, COD emissions, ammonia nitrogen emissions and ecological environment water use rate, etc. The water environment subsystem is the main obstacle factor for classification index. Based on the evaluation and analysis results, relevant suggestions are put forward.
