| The natural native rural Village is a self-organized dynamic evolutionary system,whose spatial morphology follows the logic of bottom-up organization of elements.In the feedback loop process of interaction with natural and social environment,the material and spatial elements have realized the adaptation,adjustment and evolution on the whole and at multiple levels through complex organization,and achieved harmonious integration with natural and social environment.However,under the impact of the rapidly advancing urbanization process,the rural Village are facing the problem of the dual decay of material spatial morphology and social spatial morphology.The key to better perpetuate the historical appearance is to deeply understand the characteristic laws of spatial form evolution,explore the appropriate development path of spatial morphology under the influence of complex topography and landscape,and improve the adaptability of the settlement in dynamic development.Fractal optimization is a reflection of the process of mutual integration of spatial forms of settlements with natural and social environments,and fractal theory provides a new perspective and quantitative method for studying such complex spatial evolution laws.Based on this fractal law,spatial elements are interconnected to form complex and diverse spatial forms,which are reflected in complex and winding boundary forms,rich public space forms,multi-connected road network forms,and rich architectural forms of courtyard combinations and other levels.As a new concern in the field of urban and rural planning nowadays,the study of evolutionary resilience focuses on the dynamic adaptation and adjustment capacity of the system,and provides tools for studying the development of spatial elements in different historical stages.The current research on the spatial form of traditional settlements in China has undergone a transformation from the qualitative description stage to the quantitative research stage,and has developed from static and dynamic quantitative analysis to the direction of multi-method inter-evidence research combining qualitative and quantitative.The combination of quantitative analysis based on fractal theory and qualitative analysis of evolutionary resilience plays an important role in cognizing the characteristic laws of spatial morphological evolution of settlements and guiding historical landscape conservation.The complex and similar mountainous natural environment in the south central region of makes the spatial morphology of settlements present complex fractal characteristics of fragmentation and rich hierarchy.The fractal perspective can be better analyzed by taking the vernacular settlements in the south-central region of Lu as samples.In this paper,27 traditional settlements in the south-central region of Lu are selected as the entry point for the analysis of the spatial pattern evolution and tenacity of vernacular settlements.The fractal characteristics are compared and summarized.At the same time,this paper goes beyond the study of vulnerability to disturbance and focuses on the evolutionary resilience of the spatial patterns of settlements in terms of dynamic adaptation and organizational growth during the historical evolution.The paper establishes the correlation between the fractal characteristics of spatial elements and the change of fractal dimensions and the mechanism of evolutionary resilience,combines quantitative fractal analysis and qualitative evaluation of resilience,analyzes the boundary forms,public space forms,road network forms and building courtyard forms in different historical stages,and proposes targeted spatial form protection strategies on this basis,with a view to providing spatial protection planning for vernacular settlements and The aim is to provide some reference for the spatial conservation planning of vernacular settlements and the continuation of historical landscape. |
