桂林市青狮潭水库水质现状调查与评价

通过对桂林市青狮潭水库的pH、电导率、总氮、总磷、高锰酸盐指数、溶解氧、五日生化需氧量、汞等8个水质参数进行监测,系统分析了青狮潭水库东湖、西湖的水质现状以及不同水质参数在空间上的变化特征,讨论了不同水质参数之间的相关性,并对青狮潭水库5个水质参数进行了评价.结果表明,人类活动影响下的水体富营养化、生活污染、养殖业污染以及农业污染是造成水库水质污染的主要原因.另外,在评价的基础上就水库的保护和治理提出了建议.

Investigation and evaluation of water quality of blue lion tam reservoir in Guilin city

Eight water quality parameters which including pH, conductivity, total nitrogen, total phosphorus, potassium permanganate, dissolved oxygen, five days biochemical oxygen demand and mercury of the blue lion tam reservoir in Guilin city were monitored. Systematically analyzed the water quality situation of East and West lake and the different water quality parameters in the spatial variation characteristics of the blue lion tam reservoir. Discussed the correlation between the different water quality parameters, and evaluated the five water quality parameters of the blue lion tam reservoir. The results showed that under the influence of the human activities, the water eutrophication, the life pollution, the aquaculture pollution and the agricultural pollution were the main reasons of the reservoir water pollution. Based on the assessment, we put forward some suggestions on the reservoir protection and management.
