| Tourism geological resources as a geological body or landscape with tourism value,it has the characteristics of ornamentality,singularity,diversity,antiquity,richness,regionality and scientificity,and has the natural advantages that other tourism resources can not match.At present,how to excavate geological bodies or landscapes with tourism value and transform them into tourism geological resources and develop them has not received extensive attention,especially in the cliff landform this tourism geological resources,there is no systematic research results.In this paper,the relevant knowledge and theory of geology,geomorphology,landscape ecology and other disciplines are used.With the support of remote sensing and ArcGIS software,this paper probes into the distribution characteristics of cliffs on Yunnan plateau,analyses the geo-foundation of cliff landscape development and reveals its tourism value,and then selects cliff landscape suitable for tourism development and explores its tourism development ideas,so as to inject more new connotations into geo-tourism.The main conclusions are as follows:(1)Depending on geographic information data,after terrain rendering,slope extraction and contour extraction processing and analysis with ArcGIS software,according to the steep cliff labeling method proposed in Ottawa international cartographic conference,visual interpretation is carried out with the help of LocaSpaceViwer software,the distribution characteristics of Yunnan plateau cliffs are determined.The distribution of Yunnan plateau cliffs shows a spatial difference of more north and less south,more east and less west.(2)The development of yunnan plateau cliff landscape is closely related to geomorphic surface,strata,geotectonics,fault structure,rivers and other geological factors.(1)Cliff landscape mainly develops in areas with high altitude and large drop.;(2)Cliff landscape is mainly developed in limestone and sandstone distribution areas.;(3)Cliff landscape development on different geotectonic units has obvious differences.Cliff landscapes are mostly developed at the edge of geological tectonic units and at the junction of different geological tectonic units.(4)The distribution of cliff landscape is spatially consistent with the distribution of faults.As a form of fault structure,deep and large faults play a leading role in the development of yunnan plateau cliff landscape;(5)Cliff landscape mostly develops on the east side of the North-South trending River and the south side of the East-West trending river.(3)The tourism value of yunnan plateau cliff landscape is reflected in its scientific value,aesthetic value and historical and cultural value.The scientific value of the cliff landscape of yunnan plateau is shown as follows:(1)Cliff cliff yunnan plateau landscape landscape main development mainly concentrated development level in ? geomorphic surfaces(2300 ~ 2430 m),? geomorphic surfaces(1800 ~ 2080 m)and the geomorphic surface of ? level at the junction,grade ? geomorphic surfaces(1450 ~ 1600 m)on basic no cliff landscape development;(2)It becomes an external carrier to reveal the information of crustal evolution and the evolution process of tectonic movement.The aesthetic value of Yunnan plateau cliff landscape is shown in the following aspects:(1)Cliff with its own irreplaceable way of recording,scientific precision and unique to show the distribution of the historical changes of hundreds of millions of years,has the beauty of history;(2)The remains of paleontological relics on cliffs and vegetation rooted only by cracks show the beauty of life;(3)As a kind of geological structure relic,cliff landscape has experienced the change of geological environment for hundreds of millions of years,and has the beauty of movement that other resources can't compare.At the same time,some cliff cliff wall remains such as coffins,stone carvings,murals and other historical and cultural relics are the product of "historical stratification",which is the embodiment of the historical and cultural value of cliff landscape in Yunnan plateau.(4)In the space of tourism value,cliff cliff landscape resources integration,and the local geographical conditions as selection criteria,selected five cliff landscape area for tourism development,namely Xiaojiang fault cliff landscape area,Maitreya fault cliff landscape area,Jinsharivercliff landscape area,LuDian-Qiaojia cliff landscape area and Chuxiong-Xiangyun-Dayao cliff landscape area.On the basis of adhering to the principles of characteristic,reasonable development and protection,and experiential,this paper puts forward targeted development ideas of Yunnan plateau cliff landscape.The Xiaojiang fault cliff landscape area and Maitreya fault cliff landscape area developed into geologicapark mode,the Jinsha river cliff landscape area and LuDian-Qiaojia cliff scenic area developed into a cliff theme tourism experience mode,the Jinsha river cliff landscape area and LuDian-Qiaojia cliff scenic area developed into a cliff theme tourism experience mode,Chuxiong-Xiangyun-Dayao cliff landscape in a variety of resources coordinated development pattern of tourism development.(5)The tourism development of yunnan plateau cliff landscape is a relatively complex process,and the following suggestions are put forward,that is,to strengthen the development and construction of cliff geopark and promote the productization of geological tourism resources;pay attention to the reasonable protection of cliff resources and ecological civilization construction,promote its sustainable development;Pay attention to the linkage development with surrounding scenic spots and tourism resources;Actively strive for all-round support,improve tourism security. |
