摘要
鄂西南地区岩溶地貌发育,鹤峰董家河九重坡立谷较具代表性。通过本次野外调查,在总结前人研究的基础上,就坡立谷基本特征、成因及地学意义进行探讨。结果表明,董家河九重坡立谷形态不一、规模差别较大,主要发育于三叠系嘉陵江组地层中,受鹤峰向斜构造控制,呈北北东—南南西向串珠状展布,显示出独特的地貌景观特征,具有重要的地学意义和全球对比价值。
Development of karst landforms in Southwest Hubei,nine poljes are more representative in Hefeng Dongjiahe.Through this field survey,the authors discuss the basic characteristics,causes and geological significance of poljes on the basis of summarizing previous studies.The results show that the nine poljes of Dongjiahe are different in shape and scale.They are mainly developed in the Triassic Jialingjiang formation and controlled by Hefeng syncline structure.They are beaded from northeast to southwest,showing unique landscape features,which have important geological significance and global comparative value.
