【摘要】 黄土喀斯特,是黄土受到潜蚀而表现出来的一种地貌景观。这种地貌广泛分布于黄土地区。本文以陕西泾阳县口镇—龙泉黄土覆盖的洪积扇和台原区的黄土喀斯特为研究对象,对黄土喀斯特及其构造基础、黄土灾害地貌及其成因进行了较为深入的研究。文章认为:黄土喀斯特的分布具有一定的区域性;构造节理控制了相应地区的黄土喀斯特地貌形态、展布方向和发育程度,是黄土喀斯特的重要构造基础。文章还对黄土喀斯特的特征及其演化过程进行了系统的阐述,指出了黄土喀斯特给人类生产和生活造成的危害。更多还原

【Abstract】 Loess Karst which covers loess area extensively is a geomorphiologic landscape formed in result of erosion along cavities.Taking the Loess Karst on the diluvium fan covered by loess and the loess terrace in Kouzhen-Longquan,Jingying County, Shaanxi Province as an object of study,the authors profoundly study on the structural base of Loess Karst, loess disaster geomorphology and its genesis.It is concluded that a certain pattern of spatial distribution does exist in the Loess Karst landforms.The Loess Karst geomorphic features,the direction of its distribution and degree of its development are controlled by the structural joints, which is an important structural basis in studying the formation of Loess Karst.The paper also systematically expounds the features of Loess Karst and its evolution process,and points out the harm to human life and production.更多还原
