潜蚀作用是指土层内部在地下水浸湿和活动的影响下,使可溶性物质溶解流失,粘土微粒被冲刷带到下部的过程。潜蚀作用的结果常使土层发生塌陷现象。地下水的剥蚀作用。包括机械的和化学的两种方式,但以化学潜蚀为主。潜蚀作用可形成落水洞、溶洞、峰林、溶盆等地形。
大量抽取地下水使地下水位波动的幅度增大，从而潜蚀作用增强。
Due to the extensive pumping of groundwater, the range of phreatic fluctuation was enlarged and the suffosion was enhanced.
岩溶区地下水或地表水的活动，将对土层产生潜蚀作用及崩解作用，进而形成土洞。
The underground erosion and disintegration produced by the activity of ground water will result in formation of soil caves.
