摘　　要：岩石是地貌演化发育的物质基础 ,不同的岩性分布区常常发育特定的地貌形态。本文统计分析了喀斯特地区 2 2个中小流域的地貌类型和岩石的出露关系 ,从量上揭示了流域地貌与岩性的关联规律。分析结果表明 :在碳酸盐岩出露的地区常发育着峰丛洼地 ;在碳酸盐岩夹碎屑岩出露地区易于形成峰丛谷地 ;在非碳酸盐岩出露地区发育形成非喀斯特地貌 ;而在峰林谷地和非喀斯特地貌分布区常有松散岩出露。The material bases for the evolution of landform are rocks. Usually, different landforms are formed in different rocks. In this paper, the relationship between landform and the feature of rock is analyzed in 22 small or middle sized basins, and the law of their connections is discovered. It is concluded that, in the analyzed basins, Fengcong depression is usually formed in carbonate rock region, region covered by mingled rocks of carbonate rocks and clastic rocks is apt forming Fengcong valley; the region of non carbonate rocks usually forms normal landform; and there is a main distribution of the loose deposits in the region of Fenglin valley and normal landform.
