官厅水库国家湿地公园维管植物多样性

2018年3月至2019年3月期间,在官厅水库国家湿地公园内,进行了野外植物调查,研究了维管植物的物种多样性、重要值和植物区系。研究结果显示,在官厅水库国家湿地公园内,共有维管植物318种,隶属61科191属;植物区系以温带成分为主;其中,绶草(Spiranthes sinensis)和野大豆(Glycine soja)为《中国国家重点保护野生植物名录》中的国家二级保护植物,黄芩(Scutellaria baicalensis)、宽叶香蒲(Typha latifolia)、黑三棱(Sparganium stoloniferum)和眼子菜(Potamogeton distinctus)为《河北省重点保护野生植物名录》中的河北省重点保护植物。在官厅水库国家湿地公园内的5处调查样地中,官厅水库西北岸浅水河漫滩-沼泽中植物群落的优势度指数、多样性指数和均匀度指数都相对最高。

Diversity of Vascular Plants in Guanting Reservoir National Wetland Park

From March 2018 to March 2019, in order to study the species diversity, important value and flora of vascular plants, a field survey on the plants in Guanting Reservoir National Wetland Park was carried out.The results showed that there were 318 kinds of vascular plants belonging to 191 genera and 61 families in the wetland park. The flora is mainly temperate zone. Among them, Spiranthes sinensis and Glycine soja are listed as second-class protected plants in the List of Wild Plants under Key Protection in China. Scutellaria baicalensis, Typha latifolia, Sparganium stoloniferum and Potamogeton distinctus are listed as key protected plants in Hebei province in the List of Wild Plants under Key Protection in Hebei Province. In the five surveyed plots in the wetland park, the dominance index, diversity index and evenness index of the plant community in the shallow flood plain and marshes in the northwest bank of Guanting Reservoir were relatively the highest.
