| 摘 要： | 为富营养化水体的治理提供理论依据,采用室内静态试验,研究菹草(Potamogeton crispus)、苦草(Vallisneria spiralis)和轮叶黑藻(Hydrilla vertillata)3种沉水植物夏秋两季对水体中氮磷的去除效果及动态规律。结果表明:1)3种沉水植物对水体中总氮的去除效果秋季好于夏季,菹草的去除效果最好。2)3种沉水植物对水体中总磷的去除效果夏季好于秋季,轮叶黑藻的去除效果最好。3)植物正常生长能增加水体溶解氧浓度,植物腐败死亡会导致水中溶解氧迅速降低。4)植物的腐败死亡对水体中总氮含量影响不大,对总磷含量的影响大。5)总磷的去除率与水温显著相关。
