| 中文摘要:陕西商南金丝峡国家地质公园成立于2009年8月, 以岩溶峡谷、多层岩溶溶洞及十三级瀑布群地质遗迹为特色, 包括白龙峡景区、黑龙峡景区、青龙峡景区、石燕寨景区及丹江源景区五大景区, 是我国著名的岩溶峡谷型地质公园。岩溶峡谷地质遗迹具有多样性, 在空间上总体有隘谷-嶂谷-峡谷(狭义)展布的规律。公园位于南秦岭构造带, 岩石主要由白云岩、白云质灰岩、石灰岩组成, 该岩溶峡谷景观系统的形成在秦岭具有典型性, 与公园岩石地层、断裂构造、崩塌作用、新构造运动及溶蚀性径流侵蚀等因素密切相关, 其形成机理具有自身的独特性, 称之为“金丝峡模式”, 即岩溶峡谷谷坡崩塌式后退、平面上呈鱼鳞状扩展的峡谷演化模式。 |

| Abstract:Main landscpes of Shangnan Jinsixia National Geopark established in August 2009 are karst valley, multilayer karst caves and waterfalls of 13 levels. The valley is the key geo-landscape. The geopark consists of Bailongxia scenic spot, Heilongxia scenic spot, Qinglongxia scenic spot, Shiyanzhai scenic spot, 13 level waterfalls scenic spot and Danjiang River source scenic spot. The rock types of the geopark are mainly limestone and dolomite, and the geopark is located in the Southern Qinling tectonic belt. The geopark karst valley landscape is distributed in the regular system of gully-glen-narrow-slit. The origin of the karst valley is controlled by factors of rocks, fractures, landslip, neotectonism and runoff. The special evolution model of the Jinsixia Valley is called “Jinsixia Model”. |
