Research On The Urban Design Of Historic Environmental Protection And Renewal From The Holistic Perspective

Historical environment is a term in heritage protection.Compared with the heritage ontology,it is the area where the heritage ontology is located.Although its value level is often not as high as the value of the heritage ontology,its existence is indispensable for the understanding of heritage value and the integrity of heritage information.Therefore,the historical environment has always been an important research object for the protection of urban features.Because there are two extremes in the treatment of the historical environment in the current urban construction: one is the large-scale demolition and construction that does not respect the history,leading to problems such as the fracture of the historical style;the other is the static protection of the single element,forming a protection and The sense of fragmentation in development and the lack of control over the overall style and pattern have led to fragmentation of the historical environment and loss of historical heritage.Facing the dilemma of the historical environment,this article first introduces a holistic urban design method based on the current historical protection research,and proposes a "one element,two sides,multi-dimensional,multi-layered" system view of the historical environment: one element is reflected in the overall historical environment,this integrity requires finding a balance among different opposing relationships;the two sides are embodied in the virtual and actual relationship of overall protection,that is,the protection of material elements and the protection of non-material elements;multiple elements are embodied in each level of the historical environment.,Including the memory,symbol and function of the virtual body,as well as the entity,block,city and landscape;the multi-dimensional value is reflected in the multi-objective level of the historical environmental protection and renewal,such as historical continuity,cultural preservation,economic development,and society Integration,ecological balance,etc.,and emphasize the overall grasp of the temporal and spatial scale of the historical environment.Second,use the method of analytic hierarchy process to build a historical environmental protection update element system.And using Liudu Temple Lane,the ancient city of Shou County,Anhui Province,as an empirical study,it analyzes the historical environment of Liudu Temple Lane from the aspects of one yuan,two sides,multi-layer time and space,and multi-dimensional value,and sorts out the current situation problems.On this basis,clarify the multiple goals,build a comprehensive urban design system for the historical environment of Liudu Temple Lane,use expert scoring and fuzzy comprehensive evaluation methods to calculate element weights,based on the analysis results,from landscape,city,block and building Propose guidance for urban design in different spatial scales.By emphasizing the concept of “one element,two sides,multiple dimensions,and multiple levels” of the integrity of the historical environment,it combines protection and renewal with urban design,and conducts research on the elements of historical environmental protection and renewal.This article tries to use a holistic way of thinking to solve the connection between historical elements and the surrounding environment,to achieve the integration of historical environmental space and modern life needs,and to provide theoretical reference and practical guidance for the protection of urban historical environment,urban renewal and urban style management in my country.
