中文摘要：

以陆生植物美人蕉（Canna generalis）、紫背万年青（Rhoeo discolor）为对象，研究了其不同的种植方式对净化富营养化水体中磷的影响．结果表明，美人蕉、紫背万年青的双倍生物量组对水体中TP、DTP和DIP的去除率与它们的单倍生物量组呈显著性差异，植物对水体中P的去除效果随着植物生物量的适度增加而提高．两种陆生植物的复合种植体系对TP、DTP和DTP的去除率和单一种植体系差别不明显，说明美人蕉、紫背万年青的不同种植体系对水体中TP、DTP和DIP去除率的影响不大．从美人蕉、紫背万年青去除水体中TP、DTP和DIP的动态过程拟合模型可以看出各植物处理组对水体中不同形态P有良好的去除效应．

英文摘要：

The study on the effect of terrestrial plants（Canna generalis and Rhoeo discolor）with different planting patterns on phosphorus removal in entropic water showed that the removal rates of TP,DTP and DIP in both Canna generalis and Rhoeo discolor＇s double biomass groups had significant differences with the ones in their single biomass groups. The removal rate of P in eutrophic water increased along with the plant biomass proper increasing. The complex system of Canna generalis and Rhoeo discolor had no significant difference on purifying TP,DTP and DIP with their monoculture systems. The result indicated that the effect of Canna generalis and Rhoeo discolor in different planting systems in removing TP,DTP and DIP from water was not significant. The fitting method of dynamics processes of removing TP, DTP and DIP by Canna generalis and Rhoeo discolor showed that the two terrestrial plants had good removal effect on 3 different forms of phosphorus in water.
