摘　　要：利用筛选出来的芦苇(Phragmites australis Trin)、茭草〔Zizania latifolia(Griseb.)Stapf〕、香蒲(Typha orientalis Presl.)、菱角(Trapa natans Linn.)、莲(Nelumbo nucifera Gaertn)和菹草(Potamogeton crispus Linn.)6个工具物种,在小柘皋河道内进行水生植物群落重建恢复试验工程,并对该河道工程区内的水质进行1 a检测.结果表明:恢复后小柘皋河植被面积占整个河道的65%～75%,河道水生植物年生产量约1.42×106 kg(以湿质量计),相当于1.98×1012 J(能量);河道内的水生植物都具有一定的抗水力冲击负荷能力,能适应河道污水水质和水量均不稳定的动态变化特征,并对污水中CODCr,TN,NO3--N,TP和NH4+-N等均有去除作用,去除率平均值分别为23.61%,25.00%,26.37%,32.93%和33.55%.We carried out an aquatic plant community rebuilding ecological recovery experimental project through the use of six screened model species in Xiaozhegao River.The model species were Phragmites australis Trin,Zizania latifolia（Griseb.） Stapf,Typha orientalis Presl.,Trapa natans Linn.,Nelumbo nucifera Gaertn and Potamogeton crispus Linn.Water quality was detected in the engineering area annually.The results showed that： 1） the vegetation coverage of Xiaozhegao River rose to 65%-75%;2）the annual production of aquatic plants was about 1.42×106 kg（wet mass）,the energy of which was about 1.98×1012 J;3） the aquatic plants had a certain resisted water attack load,and adapted to the inflow water with unstable quality and quantity;4） the water quality index declined to varying degrees;the average removal rates of NH4＋-N,TP,NO3——N,TN,CODCr were 33.55%,32.93%,26.37%,25.00% and 23.61% respectively.
