摘　　要：针对黄土路堑高边坡坡面特点,提出了采用植树防护对公路黄土路堑高边坡进行植被防护。并简要分析了植树防护的作用机理,并通过现场人工模拟降雨,分析了植树防护对黄土路堑坡面的护坡效果。试验表明:植树防护效果良好,且造价低廉,成活率高,易于后期养护等优点,为该项技术在黄土路堑边坡坡面植物防护提供有益的参考。In view of the slope face characteristics of the loess cutting slopes, it was proposed that planting trees to protection engineering for the loess cutting slope. Its protection mechanism is analyzed briefly,and through the in-situ washing-out testing of man-made rainfall,the slope protection effect and the corroded mechanism of the exposed loess cutting slope,the experiment indicated that the protection effect is good. And it provides the beneficial reference on the plant protection for the loess cutting slope.
