Spatial Analysis And Optimization Strategy Of Shuhe Ancient Town In Southern Shaanxi Province

With the advancement of the strategy of "cultural power",the voice of carrying forward and continuing traditional culture is constantly rising,and cultural heritage has become an important starting point for urban planning practice.Among them,ancient towns as an important link of cultural heritage,related research is gradually enriched,is the focus of the industry in recent years.The ancient town of southern Shaanxi,with its special ecological conservation location and unique diversified cultural bearing,has multi-dimensional values such as research dimension,art dimension and aesthetic dimension,which has become the key factor to highlight cultural confidence.In recent years,spatial alienation has become a common crux in the development and construction of ancient towns.Due to the tendency of profit-oriented and commercialization,the original force of Shuhe ancient town has been greatly damaged,and the spatial characteristics of buildings,streets and alleys have disappeared.Based on the multiple background,based on the concept of overall system,material diversity,ecological evolution,on the basis of the three theoretical perspectives,multi-factor,full scale,establish systematic and diachronic state space analytic framework,based on the specific research and analysis,parsing the inner mechanism of the ancient town space,mining town existing problems and put forward corresponding space optimization strategy.First of all,based on the carding of shu river town evolution,selection is under the stage of formation of town spatial pattern of alienation and space expansion stage carries on the concrete analysis,through the different stages of regional environmental elements,characteristic of space and the understanding of the relationship between the two,has been clear about the shu river town spatial pattern formation alienation and space expansion phase multi-scale space features the internal logic of the space elements of different factors to the regional environment connotation interpretation.Secondly,through the comparison of the spatial characteristics of Shuhe ancient town in the formation stage of spatial pattern and the spatial expansion and alienation stage,this paper summarizes its positive and negative deductions.Among them,the plane form and general layout under the whole space,the commercial space under the plane space,the type and distribution under the point space,the vertical direction,the composition,the function of the street and the intersection of the street and the lane under the line space all realize the forward deduction.The boundary properties under the overall space,the living space under the planar space,the orientation and height,the plane,the material and color under the dot space,and the direction,opening and closing,and the interface under the linear space show negative deductions.Finally,in view of the clear negative deductive space problems,the spatial optimization elements of Shuhe ancient town are determined,and the optimization principles of characteristic inheritance,tradition reference and development adaptation are put forward.On this basis,the overall spatial optimization strategy of strengthening the connection of natural boundary and weakening the definition of artificial boundary is put forward.Residential space "small group" layout,intensive use of the surface space optimization strategy;Building toward the orderly control,building plane differential repair,building height zoning control,building materials in the local use,building color coordination unified dot space optimization strategy;Linear space optimization strategy of street opening and closing remodeling,street direction control and street interface update.
