| 摘 要： | 山坡道路连接农田、果园 ,对山区经济发展有重要作用。黄土高原山坡道路存在严重的水土流失 ,侵蚀方式主要有沟蚀、泻溜、崩塌、陷穴、悬沟侵蚀与滑坡等。山坡道路网应按照小流域综合治理规划合理布置 ,其主要防护措施 :①修筑梯田 ,防止坡面径流冲刷道路 ;②将路面整修成拱形以分散径流 ;③在道路内侧修蓄水窑窖 ,拦蓄径流 ;④路面及边坡栽植草灌 ,防止雨水冲刷 |
| 关 键 词： | 山坡道路 水土流失 防蚀措施 黄土高原 黄土丘陵沟壑区 |

| Abstract: | The slopped roads link up farmlands and orchards and play an important role in the economic development of mountainous regions. The slopped roads in Loess Plateau exist a severe problem of soil and water loss. The main types of erosion are channel erosion, slumping, breakdown, cave in and landslides, etc. The slopped road net should be layout rationally according to the comprehensive management plan of small watersheds and the main protection measures are as follows: ①Building terraced fields for preventing roads be eroded by slope runoff.②Building the road surface into arched shape for runoff diversion.③Building cisterns at the inside of roads for retaining runoff.④Planting shrubs and grasses on road surface and slopes for preventing rainfall erosion. |
| Keywords: | slopped road soil and water loss erosion control measures the Loess Plateau gullied rolling loess area |
