Research On The Spatial Characteristics And Environment Adaptability Of Tibetan Settlement Space In The Meili Snow Mountain Of The Hinterland Of World Heritage Area

Taking the Tibetan living space of Deqin section of Lancang River,the hinterland of "Three Parallel Rivers" in the world heritage area,as the carrier,this thesis makes a detailed field investigation on the living space and its environment in the study area,collects the data of topography,climate and water system related to the environment,as well as the data of population,industry,income and geographical coordinates related to the Tibetan living space,and uses relevant software to analyze the environment With a large number of graphical language and data quantitative analysis,this thesis summarizes the characteristics of Tibetan living space and its relationship with the environment.The ecological environment of the study area is sensitive and fragile,which limits the construction of Tibetan living space and the production and life of Tibetan people.The traditional environmental adaptation mechanism makes the living space and the environment coexist,which is typical of sustainable development.In history,the migration and integration of ethnic groups led to the mosaic of Tibetan,Lisu,Naxi and other ethnic groups in the three parallel rivers area;The trend of Hengduan Mountains and the pinnate water system in the area lead to the location of Tibetan settlements close to mountains and water.The rapid elevation determines the three-dimensional distribution of Tibetan settlements.The different topography,such as slope and aspect,and the different climate conditions,such as temperature,precipitation and light,make Tibetan people form different resource allocation and livelihood patterns,which determine the different settlement space forms and human land spatial patterns.Taking Xidang village as an example,combined with the interview data,it is found that the spatial elements show different characteristics in the valley area,semi mountain area and alpine mountain area to adapt to the environment.The Tibetan cultural beliefs such as environmental view and spatial cognitive system are the important factors to maintain the stability of this adaptability.Finally,the environmental adaptability mechanism of Tibetan settlement space is summarized,and the research conclusions are used to guide the planning and design of settlement site selection,Spatial pattern optimization,spatial form development,courtyard space combination,etc.
