Study on Assessment of Water Environment Carrying Capacity in Sichuan-Chongqing Gaozhu New Area
Sichuan-Chongqing Gaozhu New Area is a cross-provincial new district approved by Chengdu and Chongqing government to thoroughly implement the development strategy of Chengdu-Chongqing economic circle.Based on the quality monitoring data of surface water 2021 in Sichuan-Chongqing Gaozhu New Area,along with socio-economic development and drainage planning,an assessment of the current water environmental carrying capacity was conducted for three water environment control units,namely Yulin River,Hou River,and Wentang River,within the Gaozhu New Area in accordance with the EvaluationMethod for Water Environmental Carrying Capacity(Trial).Meanwhile this paper used a one-dimensional pollutant carrying model to analyze the limit value of sewage discharge of the rivers in Gaozhu New Area,compare the limit value of discharge with the total amount of sewage discharge in drainage planning,and predict the future water environmental carrying capacity of Gaozhu New Area.In conclusion,this study showed that the current environmental carrying capacity of surface water in Sichuan-Chongqing Gaozhu New Area in 2021 was not overloaded;it was predicted that the new pollution load exceeded the pollutant carrying capacity of the Yulin River,Houhe River and Wentang River;and as predicted,the water carrying capacity of Yulin River Basin is 93.8％,and the water carrying capacity of Hou River and Wentang River Basin is 100％in 2035.
