摘　　要：中国东南部是"中国丹霞"地貌的典型代表地区,位于中新生代滨太平洋构造域的大陆边缘活动带。中生代内陆断陷盆地沉积了一套巨厚的紫红色类磨拉石建造,奠定了丹霞地貌造形成景的岩石地层基础;新近纪以来的新构造运动,使地壳差异性抬升,形成了南岭和武夷山脉等构造山地。紫红色砂砾岩建造在强烈的流水切割及重力崩塌作用下,发育了一大批极具观赏价值的丹霞地貌,构成了武夷山丹霞地貌密集带等区域性的重要旅游景观资源。从燕山期岩石地层建造到喜山期改造成景,区域构造作用始终是主导性的地球动力学因素。Southeast China is the typical representative area of ＂China Danxia＂ ,located in the active continental margin of Mesozoic-Cenozoic Marginal Pacific tectonic domain. a succession of purple red great thickness of molassiod formation is sedimented in Mesozoic Inland rift basins,which established lithostratigraphic base of Danxia landform to be scenic spots. The neotectonism since neogene period caused crust ascending variably,and lots of tectonoclastic mountainous region was formed,such as Nanling and Wuyi mountain. Purple glutenite formation was developed as a flood of admired Danxia landform Crowded belt in WuYi Montain and as important regional tourist resources by intense fluvial incision and gravity collapses. From Yanshanian and Himalayan periods,regional geological orogeny was always the leading geodynamic factor to make sediment formation as a Danxia landform.
