Study On The Landscape Evolution Of Xijingyu Village In Tianjin Based On The Theory Of Cultural Niche

Located in the southernmost part of the middle and Upper Proterozoic national geopark in Jizhou,Tianjin,it is a village with unique natural resources and diverse folk culture.In recent decades,the development of urbanization and tourism has changed the landscape of Mountain village,which has historical significance and limitations.Based on the theory of Cultural Niche,this paper studies the evolution law and dynamics of the cultural landscape in Xijingyu village from the space-time dimension.The first part is the research background and the theory summary,tries to demonstrate the rationality of the cultural niche theory research xijingyu landscape evolution.The second part is the research method construction,through the literature research,the interview discussion,the field survey and mapping constructs the landscape history model,unifies the landscape shape analysis method and the levins model niche measurement model,to estimate the breadth and overlap of landscape cultural niche in historical stage.The third part,using the above research methods,analyzes the resources of mountain culture,farming culture,clan culture and urban culture,in the generation stage of adaptation,the development stage of competition and separation and the mature stage of optimization and cooperation,the evolution of the cultural niche in the structural landscape,such as the overall pattern,the street network,the special place,the residential courtyard and other elements of the landscape space.In the fourth part,the natural adaptation and rational competition logic of the evolution of landscape culture niche are established,and the expansion and optimization of resource niche,rational selection and separation of resource niche are proposed to activate the internal and external dynamics of the construction of landscape culture niche.The fifth part,combined with the modern landscape practice of Xijingyu,summarizes the construction methods of the dominant cultural niche at present stage,such as stabilizing the landscape structure,creating multi-dimensional landscape resources,optimizing the standard cultural resources by modern technology.This paper puts forward that the future landscape practice of xijingyu needs to establish the evolution logic of cultural niche,predict the evolution trend,expand the cultural niche,adopt the strategy of dislocation competition,optimize the living environment of the cultural niche and so on.From the macroscopic point of view,this paper puts forward some suggestions on optimizing the natural cultural niche,making innovative use of the resources of farming folk culture,protecting the regional cultural resources and constructing the landscape-based cultural niche.
