摘要
花马湖位于北纬30°15′—30°18′、东经114°58′—115°1′,面积约27.5km^2。湖中分布82种2变种水生维管束植物,隶属于34科66属,其中资源植物众多。花马湖水生高等植物大型属少,小型属较多,单型属相对突出。区系地理成分以温带成分占优势,计34种,占全湖种类的40.48%。起源古老的成分也较多。通过与有关湖泊水生植物区系的比较,及区系成分的分析,说明花马湖水生植物区系具有从暖温带至中亚热带过渡的特点。
The Huama Lake lies at 30°15′—30°18′N, and 114°58′—115°1′ E. It covers about 27.5km^2. There are 34 families, 66 genera, 82 species and 2 varieties aquatic vascular plants growing in this lake. Of which 56 species are hydrophytic and emerging plants, 6 species are floating unattached plants 10 species are floating attached plants and 12 species are submerged plants, making up 66.7%, 7.1%, 11.9% and 14.3% of the total number of species respectively. The soil on the bed of the lake is very fertile and the depth is appropriate and favouring for various plants. The Huama Lake is located in the subtropic zone. The temperete floristic elements occupy a dominant position in Huama Lake. Compared with the Baiyangdian Lake, Jinpo Lake, Kunminghu Lake and Honghu Lake, the flora of Huama Lake is more similar to that of Baiyangdian Lake. The aquatic flora of Huama Lake has the character of transition from warm temperate to mid-subtropic.
