对比研究了稻草填料、塑料球形填料作为浮岛基质时及纯植物浮岛中复合植物（美人蕉和菖蒲）的生长情况，氮素污染物、总磷和CODMn指数的修复效果。实验结果表明：稻草基质浮岛中的美人蕉和菖蒲株高增长最快，其次是塑料球形填料浮岛，均优于纯植物浮岛。其中稻草基质浮岛系统中CODMn出现负增长的原因是稻草组织细胞中过量的水溶性物质释放所导致。

The growth of composite plants(canna and iris) in pure vegetal floating island and floating islands filled with straw filler and spherical plastic filler,and the remediation effects of nitrogen pollutants,total phosphorus and CODMn have been studied comparatively. The results show that canna and iris in floating island with straw matrix grow faster,and the next is the floating island with spherical plastic filler. Both are superior to pure vegetal floating island. The reason why negative growth occurs to CODMn in straw matrix floating island system is caused by the excess water-soluble substances released from histocyte of straw.
