江西省丹霞地貌发育规律及旅游区划研究

江西省燕山—喜马拉雅运动以块断作用为主,形成了一系列断裂隆起带和断陷盆地,白垩纪、早第三纪红层发育齐全。丹霞地貌主要发育于上白垩统紫红色含钙粗碎屑岩中,受盆缘断裂和中幼年河流控制,是晚第三纪以来新构造运动间歇性隆升,伴随着断裂切割、流水冲刷和风化剥蚀的产物。根据陆地卫星TM图像解译和野外实地调查,查明了全省共有丹霞地貌景观资源123处,其中新发现景点78处。丹霞地貌景观主要分布在该省周边丘陵低山区,明显受不同级别河流的流域控制,具带状分布规律,可划分出9个景观集中分布区域。赣东、赣东南丹霞地貌景观最为密集,结合红色旅游和客家文化特色,该区具有强劲的丹霞地貌旅游开发潜力。

Development of Danxia landform in Jiangxi province and its regional planning for tourism

Yanshan-Himalayan movements were predominated by block faulting in Jiangxi province,resulting in a series of uplift belts and fault basins,of which Cretaceous and Paleogene red beds developed well.Danxia landform mainly occurred in fuchsia calcic cataclastic rocks of upper Cretaceous series and was controlled by faults on the edge of the basins and rivers of the intermediate-early stage.It is generally the byproduct of neotectonic movement by intermittent uplift companied with faults cut down,running water's scouring,weathering and degradation.According to the data from TM image of landsite and outdoors investigation,the amount of Danxia landform sights in Jiangxi account for 123,among which 78 sites are newly found.Danxia landform is often distributed in hilly and low-relief terrain and obviously controlled by different drainage area of rivers and regular belt distribution.It can be divided into 9 regions.Among them,the sights of east and southeast of Jiangxi are most highly concentrated,and characteristic with the Red tourism and Hakka cultures.Therefore the place has strong potential to develop tourism of Danxia landform sight.
