...采用;Fookes (1985)等则以大地工程的观点将山崩型态 分为块体运动(mass movements)以及表面水蚀作用(surface water erosion) 两大类;其中块体运动包括崩塌(fall)、滑动(slide)及流动(flow)三种: 1. 崩塌(fall):包括了岩石或岩屑的坠落。

Rainfall-runoff simulation is the very important technique for soil erosion, non-point source pollution, surface water balance calculation and some other study fields.
降雨径流模拟是土壤侵蚀、非点源污染、地表水量平衡计算等众多研究领域的非常重要的技术手段。
Structure of saturant soil worked by water erosion is easy to collapse, and finally leads to surface saving water and losing stability.
特别是在水流的冲蚀或潜蚀作用下,易使土体结构崩解破坏,并最终导致地面塌陷积水和边坡失稳滑移。
Contour hedgerows reduced the erosion on slope surface with ephemeral gullies effectively, and the effect of soil conservation was more obvious than the effect of water conservation.
等高绿篱措施能够明显减少浅沟坡面的土壤侵蚀,且保土效果比保水效果更加明显。
