乌兰浩特-阿尔山公路两侧植被调查研究

STUDY ON THE VEGETATION INVESTIGATION ALONG THE ROADSIDES IN ULAN HOT-AER MOUNTAIN

采取常规植物资源调查的方法,对乌兰浩特-阿尔山公路两侧植物群落进行了实地调查,结果显示:公路两侧的主要天然植被类型划可分为4个植被型、4个植被亚型和9个群系;野生种子植物种类相对丰富,种子植物区系以温带分布类型占绝对优势,其中具有明显的大科优势特征;多年生草本植物占本区种子植物总种数的绝大多数;中生植物在本区占有很大的比例;公路沿线发现了内蒙古四级保护植物山丹,并提出公路建设期间应该特别注意保护该种质资源。

The research is adopted the general plant resource investigation method to measure the plant community, which grow in the roadsides of Ulan Hot -Aer Mountain. After the survey and systematic testing, we have concluded the following results： there are 4 vegetation types, 4 vegetation sub-types and 9 formations; wild seed plant is abundant oppositely; the seed plant area distributes is absolute advantaged by temperate zone type, and have the characteristic of big family advantage; perennial herbs are the dominant life form; a very great comparison is occupied by the medium living plant in this area; the Lilium pumilum, which fourth classes preteetion plant in Inner Mongolia, is discovered along the roadsides, so we should protect the plant resources specially in highway construetion.
