湖南酒埠江国家地质公园岩溶洞穴分布特征及成因分析

Analysis of Distribution Characteristics and Genesis of Karst Cave in Jiubujiang National Geopark, Hunan Province

酒埠江国家地质公园发育密集、规模宏大、景观丰富的溶洞群。在多年野外调查、勘测基础上对公园岩溶洞穴分布特征、成因等进行分析研究,对提升酒埠江国家地质公园岩溶洞穴的科学价值具有重要意义。结果表明,公园洞穴的分布在平面上具有相对集中性、在垂向上具有相对集中的分带性,且与地貌类型、地层岩性、断层带分布等密切相关。公园岩溶洞穴是巨厚层的碳酸盐在地壳运动、水、地球重力、生物等共同作用下形成的。

Jiubujiang National Geopark develops a densely, large-scale and rich landscape of karst caves. On the basis of field investigation and survey for many years, analysis and research on the distribution characteristics and genesis of caves in the geopark is of great significance to enhance the scientific value of karst caves in the Jiubujiang National Geoparkpark. The results show that the caves distribution is relatively concentrated in the plane and relatively concentrated in the vertical direction, which is closely related to the eomorphological type, stratum lithology and fault zone distribution. The karst caves in the geopark are carbonate with huge thickness, formed under the combined action of crustal movement, water, gravity of the earth and living things.
