福州东湖湿地公园规划区维管植物的区系组成

Flora Composition of Vascular Plants in the Planning Area of Donghu Wetland Park,Fuzhou

福州东湖湿地公园规划区位于福州滨海新城中部的核心区,维管植物资源丰富,然而本底资料不明,亟待开展植物区系研究,为该区域生物多样性保护提供支撑。据初步统计,福州东湖湿地公园规划区共记录202种植物,隶属于74个科,166属。其中,蕨类植物5科6属6种,裸子植物1科1属1种,被子植物68科159属195种,含双子叶植物57科124属150种,单子叶植物11科35属45种。菊科和禾本科是该区域植物区系组成的重要组成部分。福州东湖湿地公园规划区维管束植物多为世界广布类型,其次为热带分布型,而温带成分在该区域也有一定的渗入。属的分布区类型以泛热带属占明显优势,植物区系中属的温带性较弱,无中国特有科及属。说明规划区植物即使多数是世界广布科,但是也多分布偏向热带、亚热带性质的属。且人为因素在该区域植物区系组成中的作用不可忽视。

The planning area of Fuzhou Donghu Wetland Park is located in the core area of Fuzhou Coastal New City,with rich vascular plants in its wetlands.However,the background information is still unclear.There are 74 families,166 genera,202 species varieties based on survey.Among them there are 6 species of fern which belong to 6 genera and 5 families and 1 family 1 genera 1 species,belong to Gymnospermae,68 families 159 genera 195 species belong to Angiosperm.54 families 124 genera 150 species,belong to Dicotyledoneae,17 families 61 genera 86 species,belong to Monotyledoneae.Among them,Compositae and Gramineae are important parts of the flora.The vascular plants in the planning area of Fuzhou Donghu Wetland Park are mostly the cosmopolitan type,followed by the tropical type,and the temperate component also has certain infiltration in this region.The geographical composition of vascular plants genera in the planning area was dominated by the pantropic genera,while the temperate genera in the flora was weak.There is no endemic family and genra of China in this area.In conclusion,most plants in the planning area are members of the cosmopolitan family,but they are mostly distributed in the genus with tropical and subtropical characteristics.Moreover,the role of human factors in the flora composition of this region cannot be ignored.
