摘要
陕北黄土丘陵沟壑区 ,生态环境脆弱 ,水土流失严重 ,作为环境脆弱带的山坡生产型道路 ,对加剧土壤侵蚀起着重要的作用 ,属等外路。人们并不很重视的山坡生产型道路却与农村生产运输、经济交流密切相关 ,其建设与维护具有重要意义。通过对延安黄土丘陵沟壑区山坡生产型道路侵蚀状况调查及对道路防蚀建设的经验 ,总结了现有山坡道路侵蚀现状、方式、影响因素 ,并从生物。
In the loess plateau hills gully area of North Shaanxi, the ecological environment is fraqile and soil erosion is serious. In environmental fraiqile belt, the side hill productive road reacts on pricking up soil erosion much. However, it belongs to substandard road, and people don't think much of it. But it is every important for the productive transportation and economy intercourse of the area. So its construction and maintenance have important significance. Through investigating the actuality of the erosion of side hill productive road and utilizing experiences of anti erosion road building accumulated, the erosion actuality, modes and influencing factors are summarized and the design of anti erosion measures through biology and engineering measures is expounded.
