摘要
马边环崖丹霞以规模宏大、形态独特的弧形绝壁为特色,环崖平面闭合度可达200°~300°,蔚为壮观,具极高的研究价值和对比分析意义,是西南环崖丹霞带上的另类丹霞,以“环崖、顶平、麓缓、无瀑”为主要组合特征,主要为侧向侵蚀和重力崩塌等作用形成。
The ring cliff Danxia landform in Mabian,Sichuan is characterized by magnificent scale and unique form with plane closure up to 200°-300°.The magnificent landscape is of very high research value.Its“ring cliff,smooth top,gentle foothills,no waterfall”landscape association is unique,too.This ring cliff Danxia landform is formed by side erosion and gravity collapse.
