北方高校景观水体富营养化评价研究

Study on the Eutrophication Evaluation for Landscape Water in North College

2015年4月至5月,对北方某高校景观水体进行采样分析,并对水质状况和富营养化程度进行了调查和分析,结果表明,水体中TN,TP含量较高,N/P约为2.6,属于氮控制水体,水体受有机污染不太严重,但有加剧趋势;此外,通过采用单因子评价法,综合水质标识法,综合营养状态指数法对水体富营养化程度进行评价,水体属于富营养化水体,随温度的升高,藻类爆发的可能性很大。

The landscape water in the north college was investigated from April to May of 2015 to evaluate the water quality and the eutrophication degree. The results showed that the content of total nitrogen （TN） and total phosphorus （TP） were high, the N/P was 2.6 that meant the landscape water was controlled by nitrogen, the organic pollution in water was not serious but had deteriorating trend. Meanwhile, the single factor index evalu- ation method, comprehensive water quality identification index method and comprehensive nutritional state index method were used to evaluate the water eutrophic state, and the landscape water is eutrophic water. The possibility of algae bloom greatly increases with the increase of temperature.
