【摘要】 对梅州市丰顺县龙鲸河从勇士滩到狮吼滩河段的壶穴群作了调查.壶穴形态多样,大多数壶穴的长轴/短轴比在1.5以上.壶穴的深度、长短轴之比和口径沿河床上下游无明显的变化规律.不同大小、深度和形态的壶穴分布没有一定的规律.壶穴的发育与节理有密切的关系.壶穴为流水侵蚀形成,与基岩、构造、地貌和局部的流水作用有关.此前将该地壶穴报道为冰臼的误导应及时纠正过来.更多还原

【Abstract】 Potholes distributed from the Yongshi beach to the Shihou beach in the Longjing river in Fengshun County,Meizhou,were investigated.The potholes show various shapes.The axial ratios of most of potholes were above 1.5.There is no obvious rule for the depth,axial ratio and size change along the riverbed.There is also no fixed rule for pothole distribution of different size,depth and shape.But the development of pothole has a close relationship with joint.Potholes were formed by fluvial erosion.They were also related to bedrock,tectonic,geomorphology and local fluviation.Potholes in this area were previously reported as glacial potholes,which is misleading,should be corrected in time.更多还原
