摘　　要：通过对东平湖5个地区的实地调查和水质分析,结果表明:东平湖水p H值为7.62?7.89,湖水略呈碱性;湖水总硬度为3.56?4.65 mmol/L,湖水为极软水;湖水高锰酸盐指数、总氮和总磷3项污染指标存在一定程度的季节变化,9月份湖水高锰酸盐指数和总氮明显较5月份偏高,而9月份湖水总磷含量普遍低于5月份。观测结果表明,东平湖湖区水质有明显改善。Through the field survey and water quality analysis in 5 areas of Dongping Lake, the results showed that the pHvalue of Dongping Lake was 7.62-7.89, and the lake water was slightly alkaline. The total water hardness was 3.56-4.65mmol/L, and the lake water was very soft. The three pollution indexes of permanganate, total nitrogen and total phosphorusof lake water were seasonal variation to some extent. The permanganate index and total nitrogen of lake water in Septemberare obviously higher than those in May, and the total phosphorus content of lake water in September is generally lower thanthat in May. The observation results show the water quality in Dongping Lake area has been significantly improved.
