چکیده

Abstract The quality of the drinking water source reservoirs has always been a research hotspot. However, few have studies focused on over relatively long period with time series analysis. In this paper, based and hydrological data from 2010 to 2020, considering 8 parameters, CCME-WQI analysis was used explore interannual seasonal changes in Weishui Reservoir. Furthermore, main factors affecting were discussed through correlation ARIMA model is predict future. results show that seriously polluted 2012 2013. After 2018, gradually improved stabilized. addition, affected by inflow, showing characteristics poor summer winter. key parameters are TN TP, which almost 2 times higher than grade II standard standard. Through model, it predicted maintained at 80.46 indicating will be stable
