摘要
Abstract
Water quality security grade evaluation model is established using AHP method on the basis of WQI model, water eutrophication evaluation model and water environment health risk model and is applied in water quality security evaluation for four tributaries and main stream of Yangtze River in Chongqing section in Three Gorges Reservoir area. The results show that wa-ter quality security in tributaries and main stream is in a medium-upper state, however the drinking water risk to human health is relative higher and the water quality at reservoir entrance is poor;the main factors influencing water quality index are total ni-trogen and total phosphorus and the value of Cr( VI) directly determines the risk level of human health. The conclusions demon-strate that environment monitoring attentions should be laid on heavy metals besides the common eutrophication matter concentra-tion.关键词
