龙虎山世界地质公园丹霞地貌特征及与国内其他丹霞地貌的对比

A Study on the Features of Danxia Landform in Longhushan World Geopark and Comparing with Others in China

江西龙虎山世界地质公园丹霞地貌景观发育于信江盆地中生代红层中,以发育老年早期孤峰、峰林、残丘类地貌景观为特征,是我国丹霞地貌发育最好的地区之一。断裂切割、岩性差异、流水侵蚀和重力崩塌作用,是造成丹霞地貌景观差异的主要原因,同时由于所处盆地内位置、出露的红层性质以及构造发育特征的不同,也影响地貌发育的特色。目前国内所发现的丹霞地貌主要分布于东南、西南和西北地区。由于它们所处的大地构造位置、地壳活动特征、自然地理条件的不同,丹霞地貌的成因机制也不相同。阐述了龙虎山世界地质公园丹霞地貌景观类型及其特色,并着重研究丹霞地貌景观的成因机制,以及与其他地质公园、遗产地进行比较研究。

The Danxia landform in the Jiangxi Longhushan World Geopark is developed in the Mesozoic red beds in Xinjiang basin that is a typical example of our country＇s Danxia landforms in its early aged phase with the feature of isolated peak, stone peak forest, monadnock. The cutting of fractures, variance of rock character of the red beds, the corrosion of flows and the sliding of the gravity force are the main reason that cause the variance of the Danxia landforms. Moreover, the different place of the basin with exposed of variance red beds and the feature of the structure, are also affect the diversification of the Danxia landforms. The danxia landforms that have been discovered so far are mainly distributed in three areas in China, southeast, southwest and northwest respectively. The geneses of landform are different between each other for their different tectonic settings, the features of the crust movement and the physiographic conditions. In this paper the types and features of the Danxia landforms in the Longhushan World Geopark are represented and the geneses are studied and compared with others of the danxia landform of the world heritages, nation and world geoparks in China emphatically.
