Development features of nine poljes and structural relationship of underground river system in the southwest area of Hubei

摘要: 鄂西南地区广泛出露碳酸盐岩，形成了丰富的岩溶现象，特别是在鹤峰县及周边地区发育了目前已知规模最大的坡立谷群以及典型的地下暗河系统，研究其发育特征和结构关系对阐明该地区岩溶发育过程具有重要的参考意义。在总结前人工作成果的基础上，对鹤峰县燕子乡92.53 km2范围内的岩溶现象进行调查。调查共发现坡立谷9处，坡立谷的规模差别较大，形态不一，且处于不同的演化阶段；但坡立谷的展布方向大致相同，并与区内的构造线方向接近一致。强烈的岩溶化不仅形成了坡立谷，也形成了区内复杂的地下暗河系统，其入口和出口的发育受构造控制。Abstract: The carbonate rocks are exposed widely in the southwest area of Hubei province, forming a rich karst phenomenon. Particularly, it has been confirmed that the largest polje group has developed with typical underground river system in Hefeng county and nearby towns. Research on the development characteristics of nine poljes and structural relationship of underground rivers system is of great significance to reveal the formation process of karst in the area. The geological background and previous research has been reviewed and based on this, the karst phenomena in the scope of 92.53 km2 area in Yanzi village, Hefeng county was investigated. We have found a total of nine poljes, which are different in scales, patterns and evolution stages. However,the distribution of the slopes is roughly the same, and largely follows the regional structure in the area. In addition to the poljes, complex underground river system has also been formed with the strong karst processes. The development of the entrances and exits of these underground rivers are controlled by the regional tectonics.
