| As the humanistic representation and space-time mark of the traditional life scenes and the cultural atmosphere of the times,the historical and cultural blocks,after a long history of precipitation,record the historical evolution track of the city,reflect the diversity of social life and cultural composition,and are the most intuitive and typical portrayal of the synchronous integration and historical inheritance of urban culture [].As a historical and cultural street block,Xi’an Hui Square is the largest Hui gathering area in the province,with typical characteristics of social integrity,cultural continuity and spatial self-organization.Different from other historical districts,Huifang has a complex social relationship of blood,business and ethnic ties in addition to geographical ties.The adaptation and integration of the three major cultures(Hui culture,Chinese traditional culture,and Guanzhong regional culture)together generated and constructed the value system,belief tradition,and daily production and life style of Hui residents.Since the founding of the People’s Republic of China in 1949,Huifang has experienced changes from ethnic residential areas to tourist districts,from traditional food streets to "Internet Red" card printing places.On the one hand,it still maintains the temple space pattern of "living around the temple and doing business according to the square",the building use mode of "living in front of the shop and living in the back,living in the back of the shop",and a living heritage landscape with a dynamic and strong ethnic cultural atmosphere.On the other hand,it also presents the space performance that adapts to the social development,such as the multi-scale cultural landscape gathering,the mutual integration of multi-functional land,and the collage of diversified architectural styles.Therefore,the Huifang space is the result of the continuous adaptation and accumulation of the Hui people to the social environment for hundreds of years.This adaptation reflects the complex feedback mechanism and the coupling relationship between the social,cultural,economic system and the spatial form under the environmental change.Based on this,from the perspective of the adaptability of Huifang in the face of environmental changes,it emphasizes the continuous adaptation,learning and innovation capabilities of culture,economy,organization and space systems.According to the logic main line of "process analysis feature identification mechanism analysis strategy response",taking time as a sequence,taking the transformation and adaptability of spatial form in the face of its own resource mining and the restructuring changes of external forces as the process analysis framework,taking "temple boundary,functional structure,morphological elements" as the analysis unit,focusing on the complexity and adaptive feature identification of spatial form,On this basis,we will explore the multi-dimensional resilience driving mechanism of culture,economy and organization that runs through the evolution of the spatial form of Huifang,and deeply analyze the interaction mechanism between the spatial form and the driving forces of different dimensions.And try to construct the evaluation system and promotion strategy of spatial form guided by toughness promotion.Through research,the main achievements of this paper are as follows:(1)By sorting out the main political,economic and socio-cultural events and processes of Huifang from 1949 to2020,a multi-scale time line has been established at three levels of China,Xi’an and Huifang,and key driving factors of system and morphological changes have been identified to determine the historical stages of spatial morphological evolution;(2)Based on the adaptive cycle theory,this paper analyzes the adaptive change process of Huifang’s society economy culture space,identifies the complexity of space form and the adaptive characteristics of social economy,and summarizes the adaptive evolution mode of Huifang’s space form;(3)Explain the driving logic of culture,economy and organizational resilience behind the evolution of Huifang space form,and reveal the dynamic mechanism of space evolution based on this value.And on this basis,further analyze the evolution mechanism of spatial morphology under the action of different dimensions of power;(4)The index system of spatial form resilience measurement based on the combination of social ecological system and form elements is constructed,and on this basis,the development strategies of sustainable development strategies at macro,meso and micro levels guided by resilience enhancement are proposed. |
