| 摘 要： | 研究了国道212线陇南段沿线区域的水土流失特征及其影响因素。结果表明,研究区泥石流侵蚀强度远大于土壤侵蚀强度;人为因素是水土流失和泥石流发育最重要的外动力条件。水土流失的防治应采取综合措施,处理好公路建设与沿线泥石流防治的关系。

| Abstract: | Longnan is one of the most serious areas of debris flow calamity in our country.The low grade and bad condition of road and frequently calamity in this area restricts the development of regional economy seriously.This thesis has studied the soil erosion characteristic and influence factors along the line of the area basing on serving the construction of future G212 expressway in Longnan Area.Results indicate that,in the study area,the intensity of debris flow erosion is far greater than that of the soil erosion; the activity extent of soil erosion and debris flow is mainly influenced by human factors; to control soil erosion,integrated measures should be taken and the relation between G212 expressway construction and debris flow prevention should be handle well. |
