中文摘要	本文提出了表层岩溶带径流溶蚀控制岩溶坡地发育的动力学机制；给出了锥峰和塔峰溶丘形成的模式.用提出的动力学机制，分析了降水、岩层组构等环境要素对表层岩溶带顺坡径流量的影响.文章解释了西南喀斯特地区溶丘地貌类型的区域分布规律，认为滇东高原、贵州高原和广西丘陵平原的岩性和大地构造条件差异不大，气候是这三地溶丘形态差异的主要原因：滇东高原为西南季风气候区，降水量较低，表层岩溶带顺坡径流量小，溶丘地貌以常态山为主；其余两地为东亚季风气候区，降水量较高，表层岩溶带顺坡径流量大，溶丘地貌以锥峰和塔峰为主，其中，广西丘陵平原的降水量大于贵州高原，前者溶丘地貌以塔峰为主，后者以锥峰为主。
英文摘要	Dynamic mechanism of runoff corrosion in the epikarst zone on the formation of cone and tower karst landforms and the relevant models are shown in this paper. By using the mechanics models, the influences of environmental factors, such as, precipitation and rock texture and structure on the down slope runoff discharge in the epikarst zone are analyzed. The spatial distribution of the karst hill types in the karst areas of Southwest China is interpreted and it is suggested that the Eastern Yunnan Plateau, the Guizhou Plateau and the Guangxi Hilly Plain have no significant differences in lithology of carbonate rocks and geotectonics and climate is the principle factor for the difference in karst hill shapes between the three areas. In the Eastern Yunnan Plateau experiencing the Southwest Monsoon climate, the normal hill is the principle karst hill type, because of the relatively low precipitation. 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.
