摘要

A detail measurement is made for the coastal potholes on Xichong coast of Dapeng Peninsula, Guangdong Province. The results show that :1) the coastal potholes tend to form at the weaknesses appearing in coastal rock and their shape and distribution are controlled by the weaknesses; 2) the result of pothole forming, deepening and expanding is to break down the second shore platforms; 3) coastal potholes are the products of modern coastal erosion processes and can be formed at anytime; 4) the morphological features of marine potholes are not only related to the fluid dynamics, but also to the rock hardness and the different stages in their development; 5) marine potholes can develop in all types of rocks and originate from different kinds of small pits on the rock surface; and 6) the difference between coastal and river dynamics leads to the difference in marine and river pothole shapes.
