- 摘要:
- 按三个不同的水土流失类型区将河北省沙蔚铁路沿线施工期的水土流失量进行预测分析，结果如下：（1）铁路建设导致水土流失量急剧增加，新增水土流失量是原地貌自然水土流失量的35.9倍；（2）水土流失增加幅度低中山中度侵蚀区最大，山前倾斜平原轻度侵蚀区最小，黄土丘陵中度侵蚀区居中；（3）铁路建设施工中，导致水土流失加剧的主要原因是弃土弃渣，占水土流失总量的82.9%。
- Abstract:
- According to three kinds area of soil and water loss, the amount of soil erosion is forecasted and a conclusion is made:(1) Railway construction lead to the amount of soil erosion increasing sharply, the increasing amount is 35.9 times as much as the natural amount.(2) The increasing amount in mountain area is the most, alluvial plain the lest, hilly area between two parties.(3) Under railway construction the maior cause leading to the increasing amount of soil erosion is soil and stone discarded, the amount of soil and water loss is 82.9 percent of the total.
