摘  要:
通过野外调查研究,认为土性、侵蚀通道、降雨以及黄土地区的地形地貌是形成土壤洞穴侵蚀不可或缺的四大要素。以水的作用途径、作用方式及其作用结果为主线,将土壤洞穴的形成模式概化为:冲蚀-贯通型模式、冲蚀-潜蚀-贯通型模式、湿陷-潜蚀-贯通型模式、冲蚀-潜蚀-湿陷-潜蚀-贯通型模式以及复合型模式等五大类型。

摘  要:
By means of field research,it points out that four elements are necessary when a cave erosion occurs,i.e.soil quality,erosion channel,rainfall as well as landform and topographic features.Based on the main line of the path,way and result of the action of the water,the cave erosion process is generalized into five modes:abrasion-breakthrough mode,abrasion-underground erosion-breakthrough mode,collapse-underground erosion-breakthrough mode,abrasion-underground erosion-collapse-underground erosion-breakthrough mode and the compound mode.
