摘要
贵州处于典型的岩溶青壮年发育地区,岩溶发育条件完善。黄果树瀑布是典型的岩溶侵蚀裂点型瀑布,是在河流溯源侵蚀与岩溶共同作用下逐步形成的。经历了地表河时期、落水洞时期、地下河道扩展溶蚀时期、瀑布形成时期,瀑布的后退过程中形成了现有的犀牛潭、三道滩、马蹄滩、油鱼井,反映了在河流溯源侵蚀过程中,侵蚀能力、速率是不均匀的、阶段性的。
Guizhou is a typical karst area in the youth period with perfect karst development conditions.Huangguoshu Waterfall is a typical karst erosion knickpointtype waterfall, which is gradually formed under the joint action of river traceability erosion and karstification. It experienced the surface river period, the fall cave period, the underground channel expansion and dissolution period, and the formation period of the waterfall.The existing several deep pools of the Rhinoceros Pool, Sandaotan, Matitan, Youyujing were formed in the recession of the waterfall, which reflects that the erosion capacity and rate are uneven and phased in the process of river erosion.
