摘　　要：对强化型缓冲带中的植物净化系统进行了研究,对芦苇和蒲草的净化效果进行了对比分析。结果表明:蒲草和芦苇对水体中总磷能快速吸收、吸收效果显著,对总氮和有机物效果不明显;在最低种植密度(3株/m2)时,后期芦苇对试验效果的维持比蒲草好,在中等(6株/m2)和高等密度(12株/m2)时,蒲草对试验水体中总磷的净化效果较芦苇好;蒲草植株内的总磷含量较芦苇高,在相同时间内收获相同植株数量蒲草比芦苇对试验水体中总磷的移除量更大;工程应用时建议以蒲草为主,芦苇为辅;种植密度蒲草采用3株/m2,芦苇采用6株/m2;为避免植株腐败造成二次污染,芦苇和蒲草应在10月上旬至中旬收割。The plant purifying system in the intensified buffer zones was studied, and the water quality purifying effect by Phragrnites australis and Typhaangustifolia was compared in the article. The results show that Phragmites australis and Typhaangustifolia had significant absorbing effect on total phosphor, no noticeable effect on total nitrogen and organics ,and rapid absorption phenomena on total phosphor in water. With low planting density （3 plants/m2）, Phragmites australis can maintain the better effect than Typhaangustifolia in anaphase of the experiment, with the middle（6 plants/me） and high planting density （12 plants/m^2） , Typhaangustifolia had better effect on total phosphor than Phragmites australis. The content of phosphor in Typhaangustifolia plant was higher than that in Phragmites australis plant, therefore ,it can remove more phosphor from water to harvest same amount of Typhaangustifolia Phragmites australis with in the same time. In practice,it was suggested that the Typhaangustifolia can be the main plant while the Phragmites australis can be the supplement. The planting density of Typhaangustifolia should be 3 plants/m^2 while the Phragmites australis can be 6 plants/m^2. To avoid secondary pollute due to plants decaying,Phragmites australis and Typhaangustifolia should be harvested in the first ten days to the middle ten days of October each year.
