摘　　要：广西大瑶山砂岩峰林地貌分布于大瑶山西部的莲花山和圣堂山一带,面积180 km2,由下泥盆统莲花山组紫红色砂岩形成。砂岩峰林位于海拔千米山体上部,边缘为高耸的崖壁;峰林由数以千计的石峰、石柱、垂直崖壁、凹槽组成,主要形态为柱状和锥柱状,是一处与湖南张家界相似,但成岩时代更老的砂岩峰林地貌区。峰林地貌由泥盆纪台地演化而来,经历了台地方山、嶂谷、峰丛、峰林等发展演化阶段,现处于幼年至壮年期。Dayaoshan sandstone peak forest landform, an area of 180 km2, distributed in the area of Lianhuas-han and Shengtangshan west of Dayaoshan in Guangxi is formed by purple-red sandstone of early Devonian Lian-huashan formation.Peak forest landform on thouthand meters high above the sea mountain , with the towering cliff on the edge, is composed of thousands of stone peaks, stone pillars, vertical cliffs and flutes.The main forms of these peaks are columnar and cone columnar similar to Hunan Zhangjiajie , but the petrogenic age of Dayaoshan sandstone peak forest landform is older .The peak forest landform evolved from the Devonian plat-form,experienced development stage of platform mountain , gorge,peak cluster, peak forest and so forth, is now in the prime of life from infancy.
