Evaluation and Countermeasures of Water Environment Carrying Capacity in Anyang City
Based on the pressure-state-response model,the evaluation index system of water ecological carrying capacity was constructed,and the weight of Anyang City was calculated by combining subjective and objective weighting methods to comprehensively evaluate the water ecological carrying capacity of Anyang City from 2016 to 2020.The results show that,based on the water quality law,the water environment carrying capacity of Anyang City increases year by year from 2016 to 2020 and is not overloaded in 2020.Based on the index system method,the water environmental carrying capacity of Anyang city was in overload state,critical overload state and critical overload state respectively during 2016-2018.The main controlling factors affecting the water environmental carrying capacity of Anyang city are the utilization rate of water resources development,the water consumption of 10,000 yuan of industrial added value and the related indexes of sewage discharge.Through the prediction and a-nalysis of water environmental carrying capacity,Anyang city should improve the water environmental carrying capacity from the aspects of water conservation,pollution control and industrial structure adjustment.
