摘  要：
针对黄土高原严重的道路侵蚀问题,通过室内人工模拟降雨及人工放水试验,对黄土山坡土质路与植物路侵蚀过程进行了研究,并对比分析了植物路与土质路的侵蚀过程差异及其减水减沙效应。研究结果表明,在相同的试验条件下,植物路侵蚀过程呈逐渐减弱趋势,可用对数函数进行描述;而土质路侵蚀过程呈非稳定现象;植物路具有明显的蓄流减蚀作用。

摘  要：
In order to illustrate the relatively significant antierosion effects of plants covered roads, erosion processes on earth and plants covered roads under artificial rainfall were simulated indoor and in the fields. The results showed that the processes of erosion on the earth and plants covered roads were different. Plants covered road can effectively reduce the sediment and water loess, the intension of erosion presented descrease trend, and the variations of road erosion modulus with rainfall intensity and slope gradient can be described with exponential equations; the pocess of earth covered road presented non-stability status; there is obvious effect of runoff-inceasing and erosion-descreasing for plants covered road.
