摘　　要：利用样地调查法,对瓮马铁路沿线边坡主要草本层植物种的生态位宽度、生态位重叠值及其对生境的生态响应进行了分析。结果表明:在瓮马铁路沿线主要草本种中,马兰、益母草、鸡眼草等物种的生态位宽度占有优势地位;各植物种之间的生态位重叠较小,资源的利用方式比较多样化;发展性最强的是益母草,最弱的是地毯草。植被恢复的物种选择上应以资源利用和环境适应能力强的乡土植物为先锋种,以发展能力强的植物作为伴生种。The niche breadth,niche overlap,and ecological response to habitats of the main herbaceous plant species on the slopes along the Wengma Railway were analyzed by using the sample plot inventory method.The results showed that among the main herb species along the railway,the niche breadth of herbs such as Kalimerisindica,Leonurusartemisia,Axonopuscompressus occupied a dominant position.The niche overlap among various plant species is small,and the use of resources is more diverse.The strongest expansibility is Leonurusartemisia,while the weakest is Axonopuscompressus.The species selection of vegetation restoration should take the native plants with strong resource utilization and environmental adaptability as the pioneer species,and the plants with strong development ability as the accompanying species.
