松嫩平原大庆地区种子植物区系多样性分析
|
摘要
探究了松嫩平原大庆地区种子植物区系多样性及基本特征。根据野外实地考察,初步统计到大庆地区种子植物共有64科212属393种,其中大科(21种以上)占有最大比例(45.29%),单种科数量最多且种数最少;从属的区系成分来看,温带成分占主导(73.46%),并出现了特布现象,说明该区域在植物演替、发展过程中具有一定程度的间断性;生态类型划分显示中生植物占主导(52.66%),旱生植物次之(21.77%),说明植被保留有明显的以中生植物为主体的草原植被特征。为松嫩平原大庆地区植物资源的保护和管理提供基础资料和理论依据。
The floristic diversity and basic characteristics of seed plants in Daqing area of Songnen plain were studied. According to field investigation, there are 393 seed plants belonging to 212 genera and 64 families in Daqing area. Among them, large families(more than 21 species) accounted for the largest proportion(45.29%) and single families had the largest number and the least species. According to the floristic composition of the genus,temperate elements are dominant(73.46%) and unique distribution phenomena appear, which indicates that the region has a certain degree of discontinuity in the process of plant succession and development. The classification of ecological types show that mesophytes are dominant(52.66%), followed by xerophytes(21.77%), indicating that the obvious characteristics of grassland vegetation mainly composed of mesophytes. It provides basic data and theoretical basis for the protection and management of plant resources in Daqing area of Songnen plain.
