摘要
为了研究兰新铁路第二双线张掖—红柳河段沿线植物种属组成和特性,采用样方、样线结合的方法对该线路植被进行了调查。初步调查,其张掖至红柳河段有种子植物18科52属55种,以双子叶植物占优势,其区系特征为单种属和寡种属多,优势现象明显,生态类型以旱生植物为主,这是长期适应比较干旱的自然环境的结果。查清兰新铁路第二双线沿线植物资源的数量和分布区,为该线路土壤侵蚀、风蚀等水土流失灾害防治和植物资源保护提供科学依据。
In order to analyze the composition and feature of spermatophyte genera of Lanxin Double-line railway,we conducted a survey.The results showed that there were 55 species,52 genera and 18 families,they were dominantly composed of dicotyledons and the ecotypes mainly consist of xerophytes,this situation results from long adaptation to dry natural environments.The investigation of the plant resources and distribution in Lanxin Double-line railway would provide scientific basis for preventing disaster such as soil erosion,wind erosion and protecting the plant resources.
