黑龙江蚂蚁河三角洲自然保护区种子植物属的区系研究
|
摘要
对黑龙江蚂蚁河三角洲自然保护区植物种类属的组成特征进行分析。保护区内共有种子植物374种,隶属于188属。种子植物属的区系特征如下:本区植物区系中寡种属和单种属占优势,属的分布类型多样,包括14个分布型和5个变型。其中,以温带性质居多,占比最大的为北温带分布型含变型,占总属数的52. 90%。结合保护区的地理环境,阐释了保护区内植物的分布、起源和演化等区系特征,为保护区内植物多样性的保育提供了科学的基础资料。
There are 374 species of seed plants belonging to 188 genera in Mayihe Delta Nature Reserve of Heilongjiang Province. The floristic characteristics of seed plant genera are as follows: Oligospecies and monogenera are dominant in the flora of this area,which reflects the importance of the protection of oligogenera and monogenera in this area; The genera are of various distribution types,including 14 distribution types and 5 variants,of which temperate nature is the dominant,of which the North Temperate distribution type contains 52. 90 variants,accounting for 52. 90% of the total genera. It is also clear that the temperate nature of the plants in this area is dominant.
