摘要
为掌握黑龙江哈东沿江湿地自然保护区野生种子植物资源现状,本研究于2018-2020年,采用样线法,在该保护区内对野生种子植物组成进行实地调查,并对科、属及种的区系进行分析。结果显示,该保护区内共发现野生种子植物53科162属265种(包括2亚种及3变种),均为被子植物。以菊科(Compositae)、禾本科(Gramineae)、莎草科(Cyperaceae)等为优势科,薹草属(Carex)、蓼属(Polygonum)、委陵菜属(Potentilla)等为优势属。乔木2种、灌木7种,其余256种均为草本植物。种子植物科水平区系组成上具有广泛性,属、种水平上均表现出温带属性,同时有热带属性的渗透,且在种水平上与亚寒带—寒带属性有一定的交集。
In order to master the current situation of wild seed plant resources in Hadong Riverside Wetland Nature Reserve of Heilongjiang Province, this study conducted a field survey on the composition of wild seed plants in this nature reserve from 2018 to 2020, and analyzed the flora of families, genera and species. The results showed that 265 species of wild seed plants(including 2 subspecies and 3 varieties) belonging to 162 genera and 53 families were found in this nature reserve. Compositae, Gramineae and Cyperaceae were the dominant families, while Carex,Polygonum and Potentilla were the dominant genera. There were 2 species of trees, 7 species of shrubs, and the other 256 species were herbaceous plants. The floristic composition of seed plant at family level was extensive, showing temperate attribute at genus and species level, and tropical attribute infiltration at the same time, and there was a certain intersection with subfrigid-frigid attribute at species level.
