摘要 星云湖入湖污染物负荷量80%来自面源,而河道是输送污染物的主要通道,为了削减入湖污染物,在大街河口末端修复湖滨湿地4.5 hm^2,恢复湖湾沉水植物28.8 hm^2,对表流湿地及沉水植物的净化效果进行了试验研究.研究结果表明,由于水生植物庞大的表面积吸附、分解和吸收作用、水质净化水质效果十分明显,净化大街河水317 8×10~4m^3/a,SS、BOD_5、COD_(Mn)、TN、TP的去除率分别为82.8%、60.1%、52.8%、49.2%、40 7%.河口湖滨湿地的修复不仅净化了水质,而且改善了河湾景观,恢复了湖泊生物多样性. About 80 percents of pollution of Lake Xingyun come from non-point sources, and rivers account primarily for transporting pollutants into Lake Xingyun. To reduce the pollutants, wetlands with an area of 4.5 ha was restored in estuarine areas of Dajie River. The total amount of purified fiver water was 317.8 10^4 m^3/a. It was showed that the purification efficiency was significant via the combined mechanism of absorption, decomposition and assimilation of aquatic plants. The removal rates of SS, BOD5, CODMn, TN and TP were 82. 8% , 60. 1% , 52.8%, 49.2% , and 40. 7%, respectively.
