description Based on grey water footprint theory and the characteristics of the water resources system, this paper constructs the evaluation index of the water environment carrying capacity of the Yangtze River Economic Belt, and calculates the point-source grey water footprint, non point-source grey water footprint, and water environment carrying capacity of the study area from 2012 to 2017. The results show that the non point-source grey water footprint is much larger than the point-source grey water footprint. The non point-source grey water footprint decreased from 1,089.75 billion m3 in 2014 to 1,038.7 billion m3 in 2017, indicating that the pollutants discharged into the water were decreasing in those four years. In addition, the water environment carrying capacity of the western and middle sections of the Yangtze River Economic Belt are in a good state, but the eastern section is overloaded. HIGHLIGHTS This study selects strong representative indicators from the root of water environment problems.; It introduces grey water footprint theory into the assessment of WECC.; It provides a basis for analyzing the relationship between production system and water environment.;
