Dynamic Mechanism of Runoff Corrosion in the Epikarst Zone on the Formation of Cone and Tower Karst Landforms
详细信息   
摘要

Tower, cone and normal karst hills are three major types of karst hills in the karst area of Southwest China. A dynamic mechanism of chemical erosion by the runoff in the epikarst zone, proposed in this paper, is able to explain slope evolution of karst hills. In the karst area, where the epikarst zone of a hill has big down slope runoff discharge, chemical erosion rate is high on the hill slope and it is prone to formation of tower and cone karst hills, otherwise prone to formation of normal karst hills. In the other two areas, the cone and tower hills are the principle karst hill types because of the high precipitation, in which the tower is the principle shape in the Guangxi Hilly Plain area with the highest precipitation while the cone is the principle type in the Guizhou Plateau with the relatively higher precipitation.
