摘　　要：于2007年12月至2008年1月为期五周的时间里,对上饶师范学院校园内三口池塘的水质进行了调查,分别测定了水体的全氮(TN)、全磷(TP)、溶解氧(DO)、生化需氧量(COD)、叶绿素a(Chla)、透明度(SD)。采用综合营养状态指数法对校园内三口池塘富营养化状况进行了综合评价,池塘1和池塘2已达富营养化,池塘3处于中营养状态。对三口池塘周围污染源进行了详细调查并分析了富营养化成因,根据分析结果提出了对富营养化的池塘实行修复的可行性措施,以达到恢复和保护校园生态环境的目的。By investigation water quality of three ponds in campus from December 2007 to January 2008, an analysis was made to development trends of parameters such as the total nitrogen （TN）, total phosphorus （TP）, solved oxygen（ DO）, biochemical oxygen demand （COD）, chlorophyll a （Chla）, transparency （SD）, respectively. Eutrophication status was carried out by calculating eutrophication status index of three ponds, the eutrophication status of pond land pond 2 was eutrophic stage, pond 3 was in mesotrophie stage. Through detailed survey of eutrophication causes around the ponds, based on an analysis of the results of the eutrophication, the feasibility measures were suggested to improve ecological environment of the campus.
