摘要
以“东北森林种质资源专项调查(2007FY110400)”为契机,经哈达岭山系森林群落植被组成样方调查,共计收录了哈达岭山系维管束植物87科301属635种,科的组成以含2~5种植物科的数量最多,属的组成以1~3种的小属为主,属的优势相对科的优势小,优势科属分别以菊科的蒿属、风毛菊属所含物种数多。属的分布区系包含13个类型和8个变型,地理成分混杂、交错、融合,存在过渡性。区系的性质以温带分布为主,以北温带分布类型为优势,世界分布类型作为其重要组成,全部为草本植物。植物区系组成和热带有着一定的联系,但受地理隔离属种组成比例不高,多为生态幅较宽或历史原因在该区生存,且存在一定数量的古老成分。
Taking the opportunity of “Special Survey of Forest Germplasm Resources in Northeast China (2007FY110400)”,through the quadrat survey of the vegetation composition of the forest community in Hadaling Mountains, a total of 87 families, 301 genera and 635 species of vascular plants in Hadaling Mountains were collected.The number of families containing 2 to 5 species of plants is the largest, and the composition of genera is mainly composed of 1 to 3 species of small genera.The dominance of the genus is smaller than that of the family, and the dominant families and genera are Compositae, Artemisia and Saussurea, respectively.The distribution flora of the genus consists of 13 types and 8 forms,the geographical components are mixed, interlaced and integrated, and there is a transitional nature.The nature of the flora is mainly temperate distribution, with the north temperate distribution type as the dominant type, and the world distribution type as its important component, all of which are herbaceous plants. The floristic composition is related to the tropics to a certain extent, but the proportion of geographically isolated species is not high, most of them exist in this area because of their wide ecological range or for historical reasons, and there are a certain number of ancient components.
