青海共和龙羊峡地质公园土林地貌特征及保护开发研究

Geomorphic Characteristics,Conservation and Development of Tulin Landform ofLongyang Canyon Geopark in Gonghe County,Qinghai Province

青海共和龙羊峡地质公园是发育极为典型的土林地貌。本文通过野外调查和国内同类型地貌的综合对比,系统分析了龙羊峡土林地貌的类型、形成影响因素及价值。共和龙羊峡土林地貌根据成因可以划分为林柱地貌、沟谷地貌、潜蚀地貌和微地貌几个类型;其地貌的形成受地层物质基础、内动力地质作用和外动力地质作用等多重因素影响,其中内动力地质作用主要为距今15万年的共和运动。综合分析认为:共和龙羊峡地质公园土林地貌适宜在保护的前提下走科普旅游、生态旅游和观光旅游等持续发展道路。

GongheLongyangCanyon Geopark in Qinghai Province is a very typical Tulinlandform.Based on the comprehensive comparison between the field investigation and the domestic landform of the same type,the paper systematically analyzed the types,forming factors and value of the Tulinlandform in LongyangCanyon.Types of Tulin Landform in Longyang Canyon of Gonghe County could be divided into forest-columnar shaped ones,gullies,underground erosion ones and microtopography.Formation of GongheTulin Landform is affected by strata materials,endogenic and exogenic geological processes.Thethe main internal dynamic geological action is the Gonghe movement 150,000 years ago.The comprehensive analysis shows that the Tulin landform of GongheLongyangCanyon Geopark is suitable for the sustainable development of popular science tourism,ecological tourism and sightseeing tourism under the premise of protection.
