摘　　要：庵家山湿地位于Ｎ２８°１４′、Ｅ１１６°３６′，面积约１．２ｈｍ２。湿地具维管束植物３３科、６０属、７９种及１变种和１亚种，其中中华水韭和普通野生稻为国家优先保护植物，武夷慈姑为中国特有珍稀植物。湿地植物以挺水植物和湿生植物为主。该湿地植物区系有２４个世界广布属，１６个泛热带分布属，分别占种子植物总属数的４１％和２８％以上；从组成种的地理成分来看，该地植被明显具地带性的特征，热带成分达３７种，占全部种类的４６％以上。由于生境的异质性，湿地植被中植物群落镶嵌现象较为明显，共优种多，没有明显的建群种。庵家山湿地是多种珍稀植物的集中产地，应重视和保护这一特殊湿地。The Anjiashan wetland lies at N 28°14′, E 116°36′, its area is about 1.2 hm 2. There are 33 families, 60 genera, 79 species, one variety and one subspecies vascular plants. Of which, Isoetes sinensis and Oryza rufipogon are key protected plants in China, and Sagittaria wuyiensis is endemic rare species. As for life forms, most plants (59 species) are emerging plants and hygrophytes. The Anjiashan wetland is located in subtropic zone. The tropics floristic elements occupy adominant position at the level of species, although there are 24 cosmopolitan genera in this wetland vegetation. Because of environmental heterogeneity, there are few edificatoes, but many co dominant species in the vegetation. There are many rare plant species in Anjiashan wetland, so it is necessary to take measures to protect this wetland.
