白虎麻塘洞穴分布特征与地貌关系研究

Research on the Relationship Between Caves Distribution Characteristics and Topographical Features in Baihumatang

地质地貌特征在大尺度上突出显现,而一些特征在小尺度上表现更为明显。洞穴的发育基于大尺度的地质地貌环境,又与小区域地质地貌发育互相影响。为了揭示小尺度内洞穴与地质地貌的关系,在毕节撒拉溪对白虎麻塘（洼地）附近的洞穴进行了探测,通过实地的探测分析,结合当地地质特征、地貌环境的特殊性,得出洼地附近的洞穴系统具有海拔分层、环形分布、水平发育与垂直发育交错等几个特征。洞穴分布特征一方面基于地质、水文基础,一方面体现与地貌发育的关系,当地地貌发育经过了3~4个主要时期,不同时期发育相关特征的洞穴系统,残留洞穴记录其重要发育特征和过程。对未来进一步研究相关地区的地貌发育与洞穴的关系提供借鉴。

Geological and geomorphologic features are obvious on a large scale, while some characteristics are more obvious in small scale. Based on the large scale geological and geomorphologic environment, the development of caves also influences each other with micro-region geological and geomorphologlc development. As to reveal the relationship among caves, geology and landforms, the caves nearby Baihumatang（depression） are detected in Salaxi Bijie. Combining with the particularity of local geological and geomorphologic features, by using field detection anal- ysis, the result shows that cave systems nearby depressions have characteristics such as layered elevations, ring-dis- tribution, interlaced horizontal development and vertical development. Based on geology and hydrology, caves distri- bution characteristics also reflect the relationship with geomorphologic development. The local topographical features development experienced three or four main periods, and different period formed cave systems with relevant charac- teristics. Caves are remained to record the important development features and processes of cave systems.
