云南石林洞穴发育特征初析

石林位于滇东喀斯特高原南部，喀斯特极其发育，以发育了典型的石林地形面闻名退途，倍受国内外喀斯特学者的关注。研究区内喀斯特洞穴极为发育，洞穴在发育分布上受到区域碳酸盐岩地层分布的控制，表现出洞穴分布的相对集中性、洞穴发育对地层的选择性和洞穴发育的成层性等特征。洞穴发育规模绝大多数为中小型洞穴；洞穴多为现代地下洞河，埋藏浅且多天窗，并且洞穴的发育延伸方向明显受裂隙构造的控制，有强烈的方向性。通过对石林地区喀斯特洞穴的发育延伸方向明显受裂隙构造的控制，有强烈的方向性。通过对石林地区喀林斯特洞穴发育条件、洞穴发育规模、分布特征和洞穴发育的古地理环境特征的条件，论述了石林地区洞穴的发育特征。

A PRELIMINARY ANALYSIS ON DEVELOPMENT CHARACTERISTICS OF CAVES IN SHILIN, YUNNAN PROVINCE

Shilin County is located at southern part of Yunnan east Karst highland, where karst develops very well She is worldwide known for the typical shilin landforms, called stone forest too well developed, which has drawn much attention of the karstologists around world Karst caves develop very well too in Shilin area The distribution of karst caves are controlled by the spatial distribution of carbonate rocks in the area, which is showed by the selective chrematistic to the strata and lithology, the comparative concentricity of karst cave development and the layered features of the caves Small and medium scale caves are dominant absolutely, most caves are modern ground river caves, which buried shallow and rich in sky-windows and the orientations of caves obvious controlled by structure fissures Based on the analysis on the cave forming conditions, the features of caves distribution and cave space structure scales, and the paleoenvironment, the cave development characteristics in Shilin are discussed
