Research On Spatial Morphology Of Industrial Remains Of The Third Front Construction In Northern Sichuan

Between 1964 and 1980,a large-scale national defense,science and technology,industrial and transportation infrastructure construction campaign guided by the idea of war preparedness was launched in 13 provinces and autonomous regions in the interior of China,known as the "Third Line Construction".Its development contributed to the development and rise of modern industry in Sichuan,and profoundly influenced the evolution of urban patterns and urbanization throughout Sichuan and the central and western regions of the country.At the same time,as an economic construction movement,this process,with transportation construction as the leader,energy and raw material industry as the foundation,national defense industry and heavy industry as the starting point,has had a profound impact on the national security situation,the national industrial development layout and economic and social construction.The northern part of Sichuan,with its excellent strategic location,natural resource conditions and industrial and agricultural base,has received large-scale planning and investment construction,and is the core hinterland of the "Third Line Construction" layout.After the end of the construction of the Third Line,a large number of physical buildings and their physical space environment were left behind.The spatial form of these industrial relics reflects the planning and design concepts and physical environment characteristics of Chinese industrial buildings and unit yards under the state of war preparation,and is a special manifestation of the integration of atypical units and industrial buildings under specific historical conditions.Except for a few relics that continue to be used,a large number of building complexes are idle,abandoned or even damaged,which is undoubtedly a great loss for the protection inheritance and utilization of the industrial heritage of the Third Line construction.Combing the existing industrial heritage resources and available space of the Third Line in northern Sichuan is of great practical significance to promote the development of regional social economy,history and culture,industry and the integration and coexistence of urban and rural spaces.This paper selects the third-line industrial relics in northern Sichuan as the research object,and introduces morphological and typological analysis methods on the basis of the investigation of their development history and existing situation,and composes and analyzes the spatial organization and functional structure of the third-line industrial relics in northern Sichuan at two levels: settlement and architecture.The spatial organization and functional structure of the industrial sites are analyzed in terms of their general pattern,location,functional organization,architectural composition,and elemental characteristics.At the same time,the spatial morphological characteristics of the third-line industrial relics in northern Sichuan are compared with those of traditional unit compounds to explore the pattern of the layout of the third-line units and highlight their special research value.Finally,we will briefly discuss the protection and utilization mode of the Third Line industrial relics according to the regional characteristics of northern Sichuan,and make some suggestions to promote the reshaping of the vitality of the Third Line industrial relics.
