Protection Planning Of Historical And Cultural Blocks Based On The Concept Of Urban Historical Landscape

With the development of urbanization,the development pressure of historical cities is increasing day by day,and the challenge and damage of new projects to historical landscape are becoming increasingly significant.There is a contradiction between maintaining historical landscape and developing modern economy and improving people’s living environment in the city,which is manifested as monotonous architecture,lack of public space,separation of block style and context,and serious commercialization.The "Historic Urban Landscape(HUL)" approach attempts to integrate the protection of urban historical and cultural heritage into urban development and rejuvenate urban heritage from a landscape perspective.In this context,this paper aims to discuss the protection of historical and cultural blocks.Firstly,it conducts an in-depth analysis of the current research situation at home and abroad,explores the formation process of the method of "urban historical landscape",extracts the core connotation of integrity,stratification and vitality,and defines its characteristics and progress.According to its characteristics,the protection principles and planning routes of historical and cultural blocks based on the theory of "urban historical landscape" are proposed.Finally,taking Xinmin Street historical block of Changchun City as the object,a series of empirical studies are carried out,including the investigation and record of "historical stratification" elements,the vulnerability and value assessment of heritage,and the formulation of protection planning strategy system.It also puts forward the protection planning measures from multiple angles,and combines the characteristics of urban historical landscape,and puts forward the role of management tools in the protection planning process and the continuation of the block style after the planning is completed.Through the empirical case,the paper summarizes the characteristics and working steps of the conservation method of "urban historic landscape(HUL)",in order to provide useful ideas and references for the conservation planning of other historic districts.
