摘　　要：根据对延河河水连续5 a的水质污染因子测定数据,运用模糊数学方法对延河的丰水期、平水期和枯水期的水质现状进行了评价.结果表明:与枯水期和平水期相比,丰水期的水质较差,导致河水水质下降的主要污染物是石油类物质.Based on water quality monitored data of Yanhe River for 5 years,water quality of abundant, usual and low water season was evaluated. The results showed that water quality of abundant water season was worse by comparing with water quality of usual and low water season,in which the main pollutant was oil that. Water quality was comprehensively evaluated by 10 indexes. The defects on traditional index-evaluation method were overcome and the results were more accurate.
