贵阳阿哈湖国家湿地公园小车河段水生植物群落结构调查研究

Community Structure of Aquatic Plants in Xiaoche River Reach of Guiyang Aha Lake National Wetland Park

本研究采用典型的样地法,对贵阳阿哈湖国家湿地公园小车河段的水生植物群落物种组成、结构和季节动态开展调查,分析其生物量及多样性变化情况,以期为湿地公园的资源保护、景观营造和湿地植被恢复提供参考。通过调查,记录到水生植物124种,隶属48科90属。通过监测分析,小车河段水生植物群落可分为4个植被生态类型14个典型的群系。其中,沉水型植被群落无明显季相变化,漂浮型植被群落呈现明显的季节性变化,群落组成变化差异巨大。

In this study,the species composition,structure and seasonal dynamics of aquatic plant communities in the Xiaoche River reach of Guiyang Aha Lake National Wetland Park were investigated by using typical plot method,and the changes of biomass and diversity were analyzed,with a view to providing references for resource protection,landscape construction and wetland vegetation restoration in the wetland park.Through investigation,124 species of aquatic plants were recorded,belonging to 48 families and 90 genera.Through monitoring and analysis,the aquatic plant community in the Xiaoche River reach could be divided into 4 vegetation ecological types and 14 typical formations.Among them,there was no significant seasonal change in the submerged vegetation community,while the floating vege-tation community showed obvious seasonal changes,with significant differences in community composition.
