中国丹霞第一瀑--赤水十丈洞成因探讨

贵州黄果树和十丈洞两大瀑布群的成因进行对比分析，十丈洞瀑布从地质背景、地层岩性特征及流水、风化和重力崩塌等内外营力作用探讨其成因，认定十丈洞瀑布是发育在河流溯源侵蚀裂点上又因岩性的差别侵蚀作用形成的。十丈洞独特的丹霞地貌景观、保存完好的亚热带森林生态环境具有极高的科研和旅游价值。

STUDY ON THE FORMING CONDITIONS IN FIRST CLASS WATERFALL OF DANXIA IN CHINA--SHIZHANGDDNG OF CHISHUI

The paper compares analysis on the formation of Huangguoshu and Shizhangdong waterfalls. It deals with Shizhangdong-first-class waterfall of Danxia in China, and studies its forming conditions on geological background, lithological characteristics, and the external causes of flowing water, weathering, gravitational force collapse and so on. It is firmly believed that it is developed in the knichkpoint of headwarn erosion of the river, and by influence of different rocks.The Danxia landfrom is special and the ecological enviroment of Shizhangdong forms a good place for tourism.
