| Abstract: | According to the statistic data and the results from regression analysis and the first and second order trend surface analyses for 4 morphological parameters (elevation of summit,elevation of depression bottom, height difference between summit and bottom and area of depression bottom) of 142 depressions surrounded by Karst peak-clusters in Pogang region of South-west Guizhou Province, it is considered that in plateau-gorge region, the development of paulopost corrosion surface is restricted by the elevation of initial surface, the formation of depression is stochastic, the deepening and expending of a depression are synchronous, and progress of corrosion leveling is both from river valley to water divide and from lower reaches to upper reaches. A waking parabola shape of longitudinal profile of underground river is shown in Pogang and Anlong regions in Southwest Guizhou Province, the evolutionary trend of Karst morphostructural type along the direction from river valley to water divide are: Peak cluster and depression-Peak forest and valley-Peak forest and/ or solution basin. Those are the gemorphological features of the plateau-gorge region where datum level descends incessantly. |
