淮河流域(安徽段)主要湿地维管植物研究

Study on Wetland Wascular Plants in Huaihe Drainage Area (Anhui Section)

淮河流域(安徽段)主要湖泊湿地维管植物有68科165属259种;科、属、种分别占全省维管植物科的30.2%、属的13.4%、种的7.1%。包含5种以上的11个较大科构成了淮河流域湿地植物的主体,其中禾本科和莎草科种类最多。区系分布区类型:蕨类植物主要有4种分布区类型,世界分布为主要类型;种子植物属有14种分布类型,其中温带分布类型占总属数的38.4%,该区湿地维管植物具有典型温带性质。湿地植物资源包括食品类,工业原料类,绿肥类,观赏类,环保类及种质资源类等。

There are 259 species wetland wascular plants, belonging to 68 families and 165 genera in Huaihe drainage area （Anhui section）. As to the flora component, the major parts in the wetland consists of 11 great families （species ≥5）, Gramineae and Cyperzceae of which are the greatest.Aquatic of fern plants species are 4 area-types, cosmopolitan is the main tape,and that of seed plants genera are 14 area-types. The genera of temperate-area-types occupied 38.4% of total genera. The resource of the wetland plants is very abundant in the food category, the raw material for industry, the kind of green manure, the kind of view and admire, the environmental protection class, and the idioplasm resources.
