摘　　要：　神延铁路风沙路基地处毛乌素沙漠边缘,干旱多风,水土流失和风沙侵蚀严重,采用生物工程对路基边坡进行防护,既可保护和加固路基的稳定性,又能达到绿化铁路两侧的效果.试验结果表明:选用柠条、紫穗槐等灌木树种护坡,成活率高,长势好,投入成本低,为神延铁路全线植物护坡推广应用提供了可靠的保证,也为今后同类自然条件下大面积应用提供理论依据.The sandy road bed of Shenmu|Yanan railway lies at the margin of Maowusu dessert. The environment is aridity and windy. The water loss, soil erosion, wind/sand erosion is more and more serious in Shenmu|Yanan railway area. Slope|protection engineering with plant not only can protect and strengthen the stability of road bed, but also can green the environment around the Shenmu|Yanan railwa. The experiment results indicate that Caragana korshinskii, Amorpha fruticosa and other rosebush have better effect in slope protect. It's survival rate is high, but the cost is low. The article offered the foundations to extend and apply the technologies of slope|protection engineering with plant in both sides of the whole Shenmu|Yanan railway.
