摘要
呼伦贝尔市环境监测站对呼伦湖多年水质监测的数据,通过进行统计分析后显示:近10年,呼伦湖水质为劣Ⅴ类,重度污染,水体富营养化较严重,富营养化程度呈逐年加重趋势。主要污染物总磷、氨氮、氟化物、高锰酸盐指数、化学需氧量以及水体营养状态指数与周围地区同期降水量相关性分析结果显示:该湖主要污染物、水体营养状态指数与周围地区同期降水量无相关,湖水水质优劣与富营养化程度不完全由其周围地区降水量决定。根据呼伦湖具体情况分析其重度污染、中度富营养化的原因,并针对污染来源提出防治对策建议。
Statistical analysis on water quality monitoring data of Hulun Lake during the last decade （2005 -2014） provided by the HulunBuir Environmental Monitoring Station showed that the water quality of Hulun Lake is worse than grade V and the already serious eutrophication pollution is worsening year by year. The result of correlation analysis showed that there is no relativity between the concentration of the major pollutants and the precipitation over the same period. Causes of the severe pollution and eutrophication were analyzed according to the specific situation of Hulun Lake and prevention countermeasure for the pollution sources was put forward.
