摘　　要：[Objective] The aim was to choose appropriate floating plant in the wetland in the north China.[Method] Pistia stratiotes L.,Eichhornia crassipes,and Hydrocharis dubia（Bl.） Backer were planted in the aquatic biological pool of constructed subsurface flow wetland system in the reservoir.Through filed investigation,the growth of the three kinds of plants was studied and their adaptability to the northern climate was concluded.[Result] Judging from the growth speed and state of the three kinds of floating plants,the biological characteristic of Pistia stratiotes L.can perfectly adapt the environment in the pool in the reservoir,followed by the Eichhornia crassipes.The growth state of the Hydrocharis dubia（Bl.） Backer was the worst one and it can not adapt to the north environment.[Conclusion] It provided references for the choice of artificial floating plant in the north area.[目的]选择适合华北地区潜流人工湿地种植的浮水植物。[方法]在官厅水库黑土洼人工潜流湿地系统的水生生物塘中分别种植大薸、水葫芦和水鳖3种植物,通过实地观测3种植物的生长状况,得出3种植物对北方气候的适应性。[结果]3种水生植物中,大薸的生长速度和生长态势均最好,其生理特征能很好地适应黑土洼人工湿地水生生物塘中水环境状况;水葫芦次之;水鳖长势最差,不适应北方环境。[结论]为北方人工湿地浮水植物的选择提供了参考。
