| With the rapid advancement of global economic integration and urban modernization,historic blocks are facing the loss of urban spatial characteristics and the convergence of urban culture,relying on the existence of space "cultural ecological balance" has been gradually destroyed.Exploring the formation and change of its "cultural and ecological balance" is an important angle to excavate the internal causes of the development and change of historic blocks,and the goal is to hope that the historic blocks will get sustainable and healthy development.Therefore,the study of cultural ecological health evaluation based on cultural ecological theory can open up a new theoretical dimension of protection and renewal of historical blocks under the concept of sustainable development.Starting from the theoretical study of cultural ecology,this paper applies its theory to the space category of historic blocks,studies the evolution and development of historic blocks from the perspective of cultural ecology,reveals the relationship between the state of different cultural ecosystems and the elements of space,society,economy and management,and explores the construction of the cultural ecological health of historic blocks.The evaluation system of degree.By grasping the internal dynamics and influencing factors of cultural ecology evolution,it is helpful to maintain the material form,cultural ecology and life characteristics of historical blocks from the root,and guide the protection and renewal of historical blocks to the road of sustainable development of cultural ecology and economic,social and environmental complex system.The second chapter is the basis of this study,which defines the concept of the health degree of the historic district and the cultural ecology.Supported by cultural anthropology,cultural geography and ecology,it discusses the logic of the spatial theory and application of cultural ecology and the systematicness,symbiosis,diversity and evolution of the cultural ecology of the historic district.At the same time,it divides the historic streets into five types: real preservation type,evolution preservation type,tourism development type,commercial development type and organic renewal type,and summarizes the interaction between culture and environment and the development of cultural ecology of historic blocks.In the third chapter,on the basis of the previous theoretical research,the value orientation and composition of the cultural ecological health are analyzed,and the evaluation contents of the cultural ecological health of historical blocks are determined.Four parts are chemical,operation and management,and 11 main evaluation factors are listed systematically in each part.The correlation between them and the cultural ecological health of historic blocks is expounded and analyzed qualitatively.The fourth chapter is the process of constructing the evaluation system of the cultural and ecological health of historic blocks,including determining the evaluation objectives,objects,contents and implementation methods;determining the weights of the four parts of evaluation factors and evaluation sets by using the analytic hierarchy process and expert scoring method;and getting the final evaluation system framework,giving points The basis of scoring is evaluated,and the grade of final health evaluation is judged.In the fifth chapter,according to the evaluation system of cultural and ecological health of historic blocks,the wide and narrow lanes of Chengdu historic blocks are used as an example to evaluate and judge their cultural and ecological health,and the corresponding strategies of protection,renewal and promotion from the perspective of cultural ecology are put forward. |
