西昌邛海湖官坝河入湖口枯水期水质调查研究

Investigation on Water Quality of Lake Entrance of Guanba River in Qionghai Lake of Xichang in Dry Season

对西昌邛海湖支流官坝河入湖口枯水期的水质进行了分析。结果表明,官坝河的总氮、总磷含量呈上升趋势;有机污染物排放量逐年增加,5d生化需氧量呈上升趋势。点源污染是邛海湖营养元素含量逐年大幅上升的主要原因。

The water quality of lake entrance of Guanba river in Qionghai lake of Xichang in dry season was analyzed,which was branch of Qionghai lake.The results showed that the contents of total nitrogen and total phosphorous in Guanba river were increasing,the organic pollutant discharge amount was increased year by year and the biochemical oxygen demand of 5 d was increasing.Point source pollution was the major cause for that the contents of nutrient elements in Qionghai lake were increased largely year by year.
