三清山旅游景区地貌景观与成因分析

Geomorphologic Landscape and Cause Analysis in Mount Sanqing Tourism Scenic Area

位于欧亚大陆东南部、有着10亿多年地质构造历史的三清山于2008年7月成功申报世界自然遗产。其坐落于华夏与扬子古板块结合带上,属一怀玉古岛弧地体。该区花岗岩发育典型,地质地貌景观世界罕见。花岗岩生态、地貌、地质构成了垂直维度上四层立体景观风景带。峰峦—峰墙—石林—峰丛—峰柱—石锥—峡谷(崖壁)—造型石八种地貌标型,记录着三清山沧海桑田的变迁。岩性、构造、外力和时间是塑造三清山罕见地貌的四把钥匙。研究发现,在地质年龄上,三清山正处于幼年—青年早期,属年轻的山脉。超坚硬的年轻岩石、岩体与外岩的差异风化、三角形"隆上隆"断块构造、深度发育的节理、充沛的雨量和人类活动影响等诸多因素综合对景观形成起到了决定性作用。

Molmt Sanqing has the tectonic evolution history of one hundred millions years, which was listed as a world natural heritage July, 2008. It locates in the southeast of Eurasia, above Huaiyu paleo island arc terrane which belongs to the the ancient Chinese plate and Yangtze paleo plate combination . It develops world ram geological landscape of granite which has complicated causes. At vertical dimension, the perfect combination of geomorphology and ecology, geology, granite forms unique four vertical landscape structure. Ridges and peaks - peak wall - stung forest - peak cluster - peak column - Stone Cone - canyon（cliff） - - plastic rock are eight types of landforms record the changes in Mount. Sanqing. Lithology , structure , the extemal condition and tinre are four keys of creating Mount Sanqing＇s unique landscape. The study finds that The Mount Sanqing scenic area granite landform is in the infancy - the adults prime developmental stages. The young and super hard rock, reck weathering, triangle ＂uplift＂ block structure, joint development, abundant rainfall and less human destruction activity etc. have critical effect to the formation of landforms.
