摘要
通过样线法和样方法对山西省沁源花坡亚高山草甸进行调查,并采用植物区系地理学的方法,对该区域植物区系特征进行研究.结果表明,研究区内共记录到维管植36科101属136种.沁源花坡亚高山草甸优势类群明显,其中,优势科有菊科、毛茛科、蔷薇科、豆科和禾本科等10个,优势属只有蒿属和委陵菜属2个.沁源花坡亚高山草甸植物生活型以草本植物为主,占比达96.32％,其中,多年生草本植物处于绝对优势地位(78.68％),1年生和2年生草本植物占比较小(17.64％).研究区内植物属的分布区类型以温带分布为主,占比80％,北温带分布植物处于绝对优势地位,温带性质显著.
Abstract
A survey was conducted on the subalpine meadow of Huapo in Qinyuan of Shanxi Province using line transects and sampling methods,and the characteristics of the plant flora in the region were studied using the method of flora geogra-phy.The results showed that a total of 136 species,101 genera and 36 families of vascular plants were recorded in the study area.The dominant groups in the Huapo subalpine meadow of Qinyuan were obvious,among which there were 10 dominant families including Asteraceae,Ranunculaceae,Rosaceae,Leguminosae,Poaceae and so on.And only 2 dom-inant genera including Artemisia and Potentilla.The plant life form of the Huapo subalpine meadow in Qinyuan was mainly dominated by herbaceous plants which accounting for 96.32％.Among them,perennial herbaceous plants were in an abso-lute dominant position(78.68％),while 1-year-old and 2-year-old herbaceous plants accounted for a relatively small pro-portion(17.64％).The distribution type of plant genera in the study area was mainly temperate which accounting for 80％of the total.Plants in the northern temperate zone were in an absolute dominant position with significant temperate charac-teristics.
