摘　　要：2007年12月—2008年9月对童子湖水库的总氮(TN)、总磷(TP)、氨氮(NH3-N)、溶解氧(DO)、化学需氧量(COD)、叶绿素(Chl-a)等进行了监测。综合水质标识指数评价结果表明,童子湖水库水质达国家地表水Ⅲ类标准,主要污染因子为氮磷营养物;综合营养状态指数评价结果表明,童子湖水库处于轻度富营养状态。建议采取种植水生植物、放养滤食性鱼类、挂养河蚌等生物措施,防治童子湖水库富营养化。The survey of water quality on Tongzihu Reservoir was carried out from December 2007 to September 2008.The monitoring indexes are TN,TP,NH3-N,DO,Chl-a,etc.The water quality of the reservoir is evaluated by using the comprehensive identification index（WQI）.The results show that the water quality of the reservoir has reached class Ⅲ of ＂National Surface Water Quality Standard＂,and the main contamination are Nitrogen and Phosphorus nutrients.The water eutrophication is evaluated by using comprehensive trophic status indices.The results show that the reservoir is at light eutrophication level.According to the current status and characteristics of Tongzihu Reservoir,the suggestion is using the biomanipulation technology including breeding fish,hanging mussel,planting aquatic plants and etc to control the eutrophication of Tongzihu Reservoir.
