| 摘 要： | [目的]为秋冬季节选育不同类型的浮床植物净化污水提供参考,为滇池流域本土植物在浮床系统中的推广应用提供理论依据。[方法]用严重富营养化水体大清河水培育美人蕉和伞草,同时设不培育植物的大清河污水为对照,研究美人蕉和伞草2种浮床植物对大清河水质的净化效果。[结果]利用云南土著植物美人蕉和伞草在秋冬季节处理大清河污水具有良好的净化效果。2种植物在污水中均能正常生长发育。对污水中TN、TP的去除率,美人蕉达到84%、80%,伞草达到77%、72%;对TN、TP的平均生物量去除速率,美人蕉为21.697、.97 mg/（kg.d）,伞草为12.315、.95 mg/（kg.d）。培育美人蕉和伞草的污水中叶绿素和浮游生物量明显下降,与原污水相比较,浮游生物量分别降低了82%和68%。[结论]美人蕉和伞草能去除污水中大部分的污染物。
