摘　　要：论文分析了戈壁风沙流区铁路沙害现状，提出了玉门地区铁路防护体系建设中树种选择的依据，并筛选了二白杨、沙枣、花棒、柠条以及线叶柳等一些适合该区铁路防护林营造的树种。研究结果还表明，在该地区的铁路沙害防治中，工程措施和生物措施相结合是一种行之有效的治理措施，“客土造林”和乔、灌、草相结合是提高铁路防护林效益的关键。Having analysed the status of railways sand calamity in Yumen region, we have proposed a basement of selecting tree species in establishing protective forest system, and have selected out some trees suitable for planting on Gobi. These trees are Populus gasuensis, Elaeagnus angustifolia, Hedyfarum scoparium,Caragana korshinskii, Salix wilhemsiana etc.. The experimental results show that the comprehensive method combining engineering and biological measures is effective in sand damage control of railway, and afforestation supported by planting on the earth which is removed from some other place to improve the local soil as well as by planting tree, shrub and grass comprehensively is the key factor in improving the benefit of protective forest.
