摘要
研究目的：研究唐古拉山越岭地段沿线广布的小蒿草草甸无性繁殖规律，指导青藏铁路建设中的植被恢复。研究结果：对移植草皮进行适当人工辅助养护，有利于草皮的生长；可仅挖移草皮上半部分15cm左右进行移植，效果与整体移植基本等同；草皮的蔓延生长能力较强，草皮块间隔15～17cm对蔓延生长最为有利。成果应用于青藏铁路环保恢复工程，产生了可观的经济效益和生态效益。
Research purposes： The researches are done on the vegetative propogation law of little wormwood in the summit area of Tanggula Mountain along Qinghai - Tibet Railway for the purpose of guiding the vegetation recover in the course of construction of Qinghai - Tibet Railway. Research results：The manually auxiliary maintenance should be done to the transplanted turf, which is helpful for the turf＇s growth. The basically same outcome can be obtained as that from integrally transplant by transplanting the 15cm upper part of turf. The 15cm - 17cm interval between turfs is the most favourable for the turf＇s growth, because turf has a perfect growing capacity. The research outcome has been applied in the environment recover project for Qinghai -Tibet Railway, which has brought about remarkable social and economic benefits.
