| The key of global tourism is rural tourism,the development of rural tourism must rely on resources,so it is very important to find new resources or integrate scattered rural resources in the era of global tourism.The Yunnan-Guizhou Plateau is one of the regions with the most concentrated karst distribution in the world,the karst landscape resources such as Shilin,caves,peak forest clusters,and natural Bridge are abundant,attracting peo ple's extensive attention and relying on it to build such as Shilin,Wanfenglin,Jiuxiang,and Azerbaijan,Kongdong and other well-known tourist attractions,and played a good comprehensive tourism benefits.At present,the value of doline group landscape has not been revealed or widely recognized.Based on the theories and methods of geography,karst,geology and other disciplines,this study explored the number,type and spatial distribution of doline groups in yunnan plateau,and revealed its value.Based on this,the author selected the funnels and explored the tourism development model,which could further enrich the relevant theories and methods of karst tourism landscape development,and provided references for the development of karst funnel resources.The main conclusions are as follows:(1)By means of LocaSpaceViwerfen ArcGIS software,the doline group in Yunnan Plateau is extracted and analyzed,and the quantity,type and spatial distribution of doline group are determined.The Yunnan-Guizhou plateau has a total of 105 doline groups,most of the doline groups are in dendritic and beaded shapes.Some of them are too large in scale and appear irregular;the doline group is mainly large-scale and densely distributed on the plateau between the Yangtze platform and the South China fold belt,between the Fuyuan-Shizong-Maitreya faults and the Xiaojiang fault zone;in terms of the size of the doline group,the oversizeddoline group are:Luliang-Shilin-Milele doline Group,Shizong-Junxi-Milele doline Group,Luliang doline Group,Luoping-Jiusong doline Group,Qiubei doline Group,Jianshui-Kaiyuan doline Group,Xundian-Qujing doline Group,Kaiyuan-Mengzi doline Group,etc;in terms of the distribution of administrative areas,large-scale development of doline group is concentrated in Luliang County,Shilin County,Shizong County,Luoping County,Maitreya County,Luxi County,Qiu Bei County,Jianshui County,Kaiyuan City,Mengzi County,Shiping County,Huize County,Xundian County,Eshan County,Yiliang County,etc.(2)The doline group is mainly developed in the Permian carbonate rock,it is mainly located on the plateau between the yangzi platform and the south China fold belt and the transition department of the fuyuan-shi zong-maitreya fault and xiaojiang fault zone,studies show that the development of the doline group is closely related to geotectonic environmental factors,such as geotectonic,fault zone and geomorphic surface,and is closely related to climate and hydrology,but not closely related to soil vegetat ion;this study also shows that there arethe result of the overall uplift of the lake ? the result of the collision between Yangtze Platform and South China fold belt and the result of the evolution of part of the groundwater system.(3)The Scientific Value of the Funnel Cluster in Yunnan Plateau: it is one of that important basis for reflect the lifting of the yungui plateau;it may be an important basis for reflecting the collision between south china fold belt and yangtze platform;large-scale development of post-dolinegroup is an important evidence to study the evolution of groundwater system in Yunnan Plateau.The Scientific Value of thedoline group in Yunnan Plateau:the Yunnan plateau doline group is one of the most spectacular natural “strange circles” in the world;most doline group combine aesthetic features of natural beauty,form beauty,line beauty,and color beauty.In addition,some doline groups also have historical and cultural value and ecological value.(4)Taking the doline group plasticity,the representative of the doline group,the local social and economic development level,location and traffic conditions as selection criteria,finally,10 doline groups were selected out of 105 doline groups for consideration of development,the selected 10 pieces of doline group are numbered 0,2,16,18,41,50,57,77,80,99.(5)The tourism show of Yunnan plateau doline group landscape is the need of the development of global tourism,rural rejuvenation and tourism geology,it should adhere to the principle of equal emphasis on development and protection,and take measures according to local conditions,highlight the principle of regional characteristics and advantages,strengthen the princip les of participation and experience,and promote the integration and development of agricultural tourism;combined with the characteristics of doline group character and the surrounding environment relationship can be considered three kinds of tourism exhibition mode:doline geological park exhibition mode,doline theme amusement exhibition mode,idyllic combined system exhibition mode.(6)The tourism development of doline group is a very complicated process,it needs not only the support and guarantee of policy,capital,talents,science and technology,but also the coordination of various interests,Consider a number of possible conditions,In order to guarantee the smooth development of tourism development,Based on this,the countermeasures and measures of doline group tourism show are put forward. |
