摘　　要：[目的]了解低温季节水生植物对富营养化城市河水的净化效果。[方法]通过静态水培方法,研究了聚草、圆币草2种水生植物及其组合对富营养化河水的净化效果。[结果]低温季节,聚草、圆币草2种植物均能生存和生长,表现出较强的抗寒性和对河水的适应性,其生长效果为聚草组>圆币草组>组合组(聚草+圆币草);与对照组相比,3个植物处理系统对河道原水CODCr的去除效果均不显著,但对TN、TP、NH4+-N净化效果较为明显,其去除效果由大到小排序为聚草组>圆币草组>组合组。[结论]该研究为城市河道低温季节水生植物的修复利用及净化效果评价提供基础数据或依据。[ Objective] The aim was to understand purification efficiencies of aquatic plants on urban river eutrophication in low temperature season. [ Method ] By the method of static water culture, purifying effects of two kinds of aquatic plants （Myriophyllum spicatum, Hydrocotyle verticillata） and their combination on urban river eutrophication were studied. [ Result ] The results showed that two kinds of aquatic plants can survive and grow in the water from urban river in low temperature season. But in the different plant processing systems, their cumulated bio- mass were different, which was in the descending order of Myriophyllum spicatum, Hydrocotyle verticillata and their combination. Compared with control group, it was obvious for three plant processing systems on the removal of total nitrogen, total phosphorus and ammonia nitrogen, but it was not obvious on the removal of chemical oxygen demand. The order of the removal effect of three different plant systems to total nitro- gen, total phosphorus and ammonia nitrogen were same, which was, Myriophyllum spicatum 〉 Hydrocotyle verticillata 〉 combination. [ Conclu- sion ] The results of this study would provide the basis data or foundation for aquatic plants restoration and utilization in low temperature season and ourification effectiveness evaluation on urban river.
