摘　　要：对内蒙古达赉湖湿地国家级自然保护区植物的组成与植物科属分析的结果表明:保护区内共有维管植物78科286属653种。其中蕨类植物1科2属2种,裸子植物2科2属2种,被子植物75科282属649种。该保护区菊科、禾本科等较大科的组成占主导地位;科的分布区类型以世界分布类型最多,其次为温带分布类型。属的组成以区域性单种属和寡种属占主体,占植物总属数的93.71%;属的分布区类型分属于13个分布区,区系成分复杂。北温带分布成分及其变型占明显优势,旧世界温带分布及其变型和温带亚洲分布型的比例较高,反映出该保护区植物科属区系具有典型的温带性质,地理联系广泛,特有程度不高。The floristic composition of vascular plants in Dalai Lake National Nature Reserve wetlands were studied. The results showed that there were 653 species of vascular plants in nature reserve, belonging to 286 genera and 78 families. Among them, there were 2 species of fern（belonging to 2 genera and 1 family）, 2 species of gymnosperm （belonging to 2 genera and 2 families） and 649 species of the angiosperm （belonging to 282 genera and 75 families）. The plants of larger famihes such as Compositae, Graraineae, Papilionaceae and Rosaceae were dominant in species composition in the nature reserve. The widespread type was the most and the temperate type was in the next place in the areal types of families. The genera mainly contained regional one - seeded genus and depauperate genus which covered 93.71% of total genera. The areal types of genera belonged to 13 different distribution areas and floristic elements were complex. The distribution and variations of north temperate type played a dominant role, and those of the old world temperate type and Asian temperate type were also in the majority, which reflected the flora in this nature reserve had typical floristic characteristics of temperate type with abroad geographic relation and low typical flora.
