摘　　要：近年来,菏泽市主要河流水体水质出现了明显好转,通过对近10年菏泽市主要河流水体水质的评价分析,菏泽市主要河流水体污染物质由10年前多个参数超出标准演变为目前个别参数超出标准,超出标准的倍数也有所降低,目前多数主要河流水体年度水质已满足《地表水环境质量标准》Ⅳ类标准。但影响河流水体水质的主要污染物质是受人类活动影响的化学需氧量和非人为因素影响的氟化物,个别河流水体水质仍不能满足Ⅴ类水标准,环境治理和环境保护任重道远。In recent years,The water quality of the main rivers in Heze has been improved significantly.Through the evaluation and analysis of the water quality of the main rivers in Heze Municipality in the past 10 years,the pollution substances in the main rivers have several parameters exceeding the standard 10 years ago and changed to individual parameters at present,and the multiple of exceeding rate has also been decreased.At present,the annual water quality of most major rivers has met the Class IV standard of"Surface Water Environmental Quality Standard".But,the main pollutants affecting river water quality are chemical oxygen demand influenced by human activities and fluoride influenced by non-human factors.The water quality of some single rivers still cannot meet the Class V water standards,and there is a long way in environmental protection and improvement.
