| 摘 要： | 以浮床水培柳树（Salix babylonica Linn）为对象，研究其在富营养化水体中2a积累的生物量、株高与生物量关系以及植物体对N、P的吸收情况．结果显示，柳树从种子到幼苗的过程中所积累的生物量鲜重平均为789g／株．2a内，在种植密度为12．5株／m^2的浮床上，每平方米柳树浮床能将34．2m^3的水从V类水净化为Ⅲ类水质（以TP计）．柳树对富营养化水体的修复进程相对缓慢，但易于管理，适宜于水体的长期净化．

| Abstract: | The study was conducted on willow(Salix babylonica Linn.) planted on the floating bed in terms of biomass,relation between biomass and height,and the removing efficiency of N and P from the eutrophicated water body.Results showed that the average accumulative biomass of willow planted on the floating bed from seed to young tree within two years was of 789 g/individule when they were planted with a density of 12.5 ind./m2.Within two years,averagely each square meter of willow floating bed was able to purify ... |
