摘　　要：在对塔克拉玛干(塔中)引种植物进行调查的基础上,对所引种的植物进行了适应性评价,并为沙漠公路防护林工程建设筛选了适宜的植物种。结果表明,塔中共引种植物274种(隶属于34科83属),现存149种,死亡86种,流失39种。引种植物中灌木、草本较多,乔木较少,藤本极少;灌木是较适宜种,引种成活率最高,乔木和草本相差不大;草本流失率最高,灌木次之,乔木最低。适宜沙漠公路生物防沙的植物种主要为灌木(31种)、草本(14种)、乔木(2种)。In this paper, we evaluate the adaptability of introduced plants on the basis of introduction plants in Taklimakan. The results showed that 274 plants （ belonging to 34 families and 83 genera） had been introduced, 148 species preserved, 87 species dead and 39 species lost. Shrubs and herbs are major living forms of introduced plants, arbors are minorities, and lianas are very few. Moreover, shrubs are adaptable species, its survival rate is the highest, herbs survival rate and arbors＇ axe similar. Herbs lost rate is the highest, then bush, and then arbors. Shrubs are the most adaptable for the shelterbelt eco -project along the trim desert highway, herbs are less. Then arbors.
