| 摘 要： | 利用WEPP（Water Erosion Prediction Project）侵蚀模型，模拟凉水自然保护区内道路（包括林内道路和柏油路）与河流的相交点的侵蚀特征，以及符合在道路长度50111内，与河流有1个以上相交点的共20个路段的侵蚀特征。结果表明，在与河流相交点的路段中，当道路坡度〉6．19％，泥沙量显著增长；20个模拟路段中，降雨径流、融雪径流、路面及路缘泥沙量、进入河流泥沙量4个模拟结果的最大值均出现在位于道路VI中的路段11；道路长度是影响道路泥沙量的主要因子。

| Abstract: | The paper has simulated intersection points between rivers and roads and 20 road segments which have more than one intersections points in 50 meters by applying the WEPP model. The modeling results include rain runoff, snowmelt runoff, sediment on road surface and sediment into rivers that shows that the erosion has significant increase when the value of road slope over 6.19%. One segment that locates in the Road VI has the peak values of four modeling results in 20 simulated road segments. Road length is the predominant factor in sediment amount. |
