Study On The Evolution Of Urban Spatial Form In Rikaze

Rikaze is located in the southwest of Tibet,is a typical plateau Valley city,mountains,rivers,wetlands,Linka,temples together constitute its unique regional space style.As a postTibetan political,economic and cultural center,the local Tibetan population accounted for 95%,is also the master of Panchen’s station,since the origin of the city has more than 1300 years of development history,with strong regional characteristics and deep national culture.The steady advancement of urbanization in the western region has greatly accelerated the pace of urban construction and brought about the crisis of urban characteristics.Under this background,the characteristics of Rikaze City style face severe challenges,in order to curb the urban characteristics of Rikaze and small towns in Tibetan areas,so the study of urban spatial morphological evolution aimed at Rikaze is carried out.Taking urban spatial form as the core,this paper explores the relationship between the evolution and spatial characteristics and the influencing factors such as nature,society,economy,culture and policy,and puts forward the strategy of protection and guidance,in order to provide a reference for protecting regional culture and constructing the characteristics of Rikaze city.Based on the present situation of the absence of the characteristics of urban construction development,this paper selects Rikaze as the research object,takes the historical development as the axis,divides the evolution course into three stages according to the evolution characteristics of the urban spatial form of Rikaze: The formation stage of the primitive rudiment(Tubo period to the Yuan Dynasty)and the Natural evolution stage(The Ming Dynasty 1447 to Tibet Liberation)and the stage of modernization construction(Tibet Liberation to this day),starting from the evolution of spatial form,summed up the spatial morphological characteristics and laws of each stage.Through the study of the background and history of the development of Rikaze City,it is concluded that the dominant influencing factors of morphological evolution are natural geography,national culture,political system and social economy.Among them,natural geography and social economy are the continuous influencing factors of the evolution of urban spatial form,and national culture and political system are the characteristic factors that determine urban characteristics.On this basis,the natural pattern of Rikaze,urban pattern,religious space,Linka,traditional village and commercial space are carried out horizontally,and the characteristics of urban space are interpreted.Finally,the article settled in the protection and guidance of urban characteristics.By summing up the influencing factors,spatial characteristics and present situation of the evolution of urban spatial form in Rikaze,this paper puts forward the guiding elements of natural ecological basement,ancient city protection,new town construction and humanistic style.Combining with the practice design,this paper puts forward a detailed strategy for the elements,aiming at better protecting and guiding the development of Rikaze’s characteristic.
