摘　　要：2007年对以再生水为补给水源的北京稻香湖园林水系进行生态修复试验。该水系正常运行,按比例投加生态修复剂和滤食性鱼类,促进再生水中有机污染物的降解及其通过食物链的转化。试验区浮游植物群落由蓝藻、绿藻、硅藻、隐藻、裸藻和甲藻构成,平均密度为2959.95×104cells/L,其中蓝藻所占56.8%。透明度平均37.4 cm,对TN、TP、CODcr的去除率分别为91.33%、94.07%、CODcr 81.96%。水质明显改善,夏秋季未发生蓝藻水华。The regenerative water was complementary water resources of garden water system of Dao Xiang lake. The experiment of ecological reparation was done at the water system in 2007 year. Ecological reparative agent and filter fishes were added into the garden water system at ratio and different time. The organic contaminants were resoved and transformed through food chain in the water body. The ceils density of phytoplankton was 2959. 95 × 10^4 L^-1 and Cyanophyta proportion was 56. 8%. The average trasparancy in experimental region was 37.4 cm. The removal efficiency of TN ,TP and CODcr was 91.3% ,94. 7% ,81.9% respectively. Water face of the lake was clear. The water quality was purified visibly. Water bloom did not happen in summer and autumn of 2007 year.
