| At present,the related research of multi-ethnic settlements in China has increasingly attracted the attention of geography,architecture,archaeology,landscape architecture and other disciplines.From the past,focusing on the textual research and spatial analysis of traditional villages,it has gradually expanded to some non-traditional but distinctive villages.The deepening of urbanization is accompanied by the continuous development of the social economy in the mixed Tibetan and Han areas of Gannan.The strong invasion of new culture,disregard for traditional culture,and changes in people’s behavior and lifestyle have led to the destruction of traditional residential forms,and the gradual disappearance of architectural techniques and ethnic characteristics.This article,based on the literature review and the coexistence of Tibetan and Han cultures and the distribution of the two ethnic groups in the Tao River Basin,selects the Zhuoni section of the middle reaches of the Tao River as the research scope,and selects typical Tibetan and Han mixed settlements-Yalu Village and Xiandi Village-as the research objects based on the settlement ethnic groups.On the basis of cultural symbiosis,the spatial form of Tibetan and Han mixed settlements is analyzed.This article is based on the theories and achievements of disciplines such as architecture,anthropology,cultural studies,and sociology,and applies research methods such as architecture.Through on-site investigation,literature review,and software analysis,the spatial form of Tibetan Han mixed settlement in the middle reaches of the Taohe River is studied.Firstly,theoretical tracing and conceptual analysis of symbiotic thinking are conducted,and inspiration for symbiotic thinking in rural settlement spatial renewal is proposed.The coordination relationship between rural settlement spatial renewal and symbiotic thinking is clarified,and the composition mode of symbiotic system in the process of rural settlement spatial renewal is defined.Subsequently,by studying literature such as county and village chronicles,the historical evolution of the middle reaches of the Taohe River and the basic situation of settlements were organized and analyzed.Secondly,case studies were conducted on typical Tibetan Han mixed settlement areas such as Yalu Village and Xiandi Village,exploring their internal macro settlement spatial pattern,meso settlement spatial characteristics,and micro settlement spatial environment.A comparative analysis was conducted with the Tibetan settlement Panqiao Village,summarizing the spatial morphology characteristics of Tibetan Han mixed settlement areas.Then,terrain,land resources,rivers,and ethnic culture were analyzed and explored The impact of natural economy on the spatial form of Tibetan Han mixed settlement in the middle reaches of the Taohe River.Finally,this article takes Tibetan and Han mixed settlement as the research object,and based on summarizing the common problems of overall economic backwardness,chaotic settlement construction,and damage to resources and environment in current development,optimizes the settlement problem based on the concept of "symbiosis".The conclusion of this study is that the Tibetan Han mixed settlement in the middle reaches of the Taohe River has adapted to various factors such as natural and social humanities,and has continuously developed,forming a unique settlement form in Gannan.Its essence is a form of joint survival,cultural integration,and production of the Tibetan and Han people in the middle reaches of the Taohe River.This article analyzes the spatial form of settlements in Yalu Village and Xiandi Village in the middle reaches of the Taohe River,aiming to explore the creation of a harmonious and symbiotic living environment and its optimization strategies,in order to strengthen the awareness of the Chinese ethnic community in the region,promote the sustainable development of the living environment in multi-ethnic gathering areas,and correctly guide the overall planning of Tibetan Han mixed settlement. |
