摘　　要：对双龙湖枯、丰水期交替期各项水质指标TN、TP、CODm n、Ch la、透明度、浊度等指标进行监测分析,运用富营养化综合评价法对双龙湖营养状态进行评价,认为双龙湖丰水期初期水质优于枯水期末期,处于中营养化水平,枯水期末期处于轻富营养状态。研究评价枯、丰水期的水质变化规律,为加强双龙湖污染防治,改善和保持水环境提供科学依据。Each water quality indicator as TN, TP, CODMn, Chla, transparency, turbidity in different season have been monitored and analyzed, using the eutrophication assessment methods to evaluate the eutrophy of Shuanglong-lake. We thought, at the beginning of high water season, the water quality obviously surpassed the end of dry season with the middle level eutrophic status in Shuanglong-lake, while at the end of dry season, it was at light eutrophic status. By analysis of the changing rule of water quality, can be provided the scientific basis for preventing and controlling pollution, improvement and maintenance of the water environment.
