【摘要】 中国是世界上研究丹霞地貌最早的国家,随着2010年"中国丹霞"世界自然遗产的成功申报,丹霞地貌作为一个地貌类型的名称已走出国门被世界所承认.在介绍广西桂平白石山丹霞地貌空间分布和景观特色基础上,对其形成条件和过程进行分析探讨,指出:(1)白石山丹霞地貌典型集中、类型齐全、景观独特,具有典型的"顶平、身陡、麓缓"的丹霞地貌特征;(2)白石山丹霞地貌是古近纪山间盆地沉积的红色碎屑岩,由构造运动盆地隆起、侵蚀、溶蚀作用、流水切割以及重力崩塌等内、外动力作用塑造形成;(3)白石山丹霞地貌具有地层沉积时代新、形态宏伟的特色,在各丹霞地貌中较为罕见,具有很高的科学价值.更多还原

【Abstract】 China is the earliest country to study Danxia landforms in the world."China Danxia",as a geomorphic term,has been recognized by the world with the successful declaration of "China Danxia" world natural heritage.This paper analyzes and discusses the formation conditions and process of Danxia landforms in Baishishan of Guiping,Guangxi on the basis of studying of its spatial distribution and landscape features.The study comes to the following conclusion:(1)Danxia geomorphology is typical and centralized,with its types complete and landscapes unique,having representative Danxia landforms characteristics of "flat tops,steep bodies,slow foothills";(2)Danxia landforms is sedimentary red clastic rock deposited in intermountain basin in Neogene,which was formed through the inner and outer dynamic action of tectonic movement,such as basin uplift,erosion,dissolution,water cut and gravitational collapse;(3)Danxia geomorphology with the characteristics of new era of strata sedimentation and magnificent shape is rare among all the Danxia landforms in the world,which has high scientific value.更多还原
