摘　　要：通过对神延铁路榆神段风沙路基边坡生物防护技术的试验研究,提出了把紫穗槐、柠条等灌木植物作为风沙铁路生物防护的首选树种,其中紫穗槐和沙地柏等灌木植物植苗栽植效果好,柠条、踏郎等灌木植物条播种植效果好,沙打旺等草本植物撒播种植效果好,采用直播方式种植的灌木植物以条播种植防护效果最好,复合种植以先浅条播柠条后再把沙打旺和紫花苜蓿种子混合撒播防护效果好,值得推广应用。实践证明,采用生物防护路基边坡,既可保护和稳固路基又能达到绿化美化铁路两侧的效果,这些都为沙区铁路生物防护提供了科学依据。Experiment on the biological protection along side slope of Shen-Yan railway was carried out.Shrubs like Amorpha and caragana,Sabina vulgalis,Astragalus adsurgens were the prioritized plants selected for side slope plantation.Different planting models and mixture patterns by different shrubs were developed.The practice showed that biological protection with side slope of railway not only can protect the slope and solidate the foundation,but also can make the landscape beautify.
