Research On Construction Of "Tea Horse Road" Of Purer Heritage Corridor Network Based On Suitability Analysis

"Tea horse road" was originated in the ancient "Tea-Horse Mutual Trade" in China’s southwestern region. Purer is the source of the Yunnan-Tibet "tea horse road", is the origin and distribution center of famous Purer Tea, has witnessed the rise and fall of Purer tea trade, experienced the evolution of cultural heritage along with the national culture. Today under the rapid development of towns and cities the road along the impact, cultural and ecological Heritage Trail along face threat of authenticity and integrity. Based on the above research background, the construction of the "tea horse road" heritage corridor network and put forward the corresponding protection strategy, has a double meaning of theory and practice.This paper determines to use the suitability analysis method for constructing heritage corridor network system. The content of this research and the main conclusions are as follows:(1) The construction of cultural heritage corridor:firstly, combing the remains Purer "tea horse road" and the intangible cultural heritage, to provide the material foundation for the construction of cultural corridor network; the use of ARCGIS and the minimum cumulative model, simulate the potential suitability of high cultural heritage corridor network. Through the analysis of the network structure that simply relying on intangible cultural heritage build the heritage corridor network is not high connectivity. For the overall construction, cultural heritage protection and further optimize the network provides the research foundation.(2) The construction of ecological corridor construction:analysis of natural elements in the region, including tea, the ancient tea, natural protected areas, rivers, use suitability model to select factors (Elevation, Slope,land use, Water), and give its weight value, to simulate the potential suitability of high ecological corridor network. Through the analysis of the network structure that only selected natural elements build ecological corridor network connectivity is higher, but the loop less. Further put forward the optimization strategy of ecological corridor. (3) The evaluation and superposition of corridor network:simply to cultural or ecological factors to construct the corridor is not perfect. The research adopts the method of Delphi expert questionnaire and AHP combination, respectively from the four aspects of historical value, ecological value, economic value, social value of integrity construction of evaluation system, and calculate the weight, together to generate double elements of cultural and ecological corridor network.(4) The evaluation of cultural and ecological corridor network:double factor analysis method using network structure, analysis of channel structure of cultural and ecological corridor network dual elements corridor. Conclusion:double element corridor network is superior to the individual elements of the corridor network. Double element corridor network connection number, connectivity between nodes, with each other to form a dense network of channels, to promote the construction of heritage corridor network, is conducive to the protection of heritage.In this paper, through the construction of heritage corridor network protection and the development of cross regional linear cultural heritage for the same reference, make up the deficiency of the current protection theory and method, to promote the protection of natural and cultural heritage.
