| Today’s urban and rural historical and cultural protection and inheritance must not only protect individual buildings,but also protect the texture of streets and lanes,urban patterns,and protect natural landscapes,cultural spaces,and intangible cultural heritage.This paper takes the Barkhor historical block as the research object,and uses the theories and methods of urban morphology,cultural ecology,and historical geography to explore the comprehensive,authentic,and dynamic protection and development goals based on contextual space units,which are value-oriented.,conducted a holistic study on the protection and control paths,strategies and specific measures of the cultural space units of historical blocks,systematically protecting the overall pattern and characteristic features of historical towns,realizing the sustainable inheritance of cultural context,and improving the living environment.Firstly,it expounds the research background,purpose,and significance,defines related concepts,and summarizes the current theoretical research status at home and abroad from three aspects: context,historical block protection,and context space unit.Secondly,combined with the traditional Tibetan construction wisdom,analyze the evolution process of the shape and pattern of the block,sort out the development and construction of the block,summarize the current problems,and classify the block space.Thirdly,by summarizing the existing methods of delineating contextual space units,a hierarchical system of contextual space units in the Barkhor Historic District is formed,with management units,morphological units,and contextual spaces as constituent elements.Through the superposition and subdivision of the three spaces,delineate 25 contextual space units,based on the existing relevant value evaluation methods,through distributing social questionnaires to block residents,tourists,believers and other groups,from the perspective of block owners,their needs and highlighting regional historical cultural Incorporate pulse value into evaluation factors,take ontology value,correlation value and basic space conditions as criterion layers,use AHP and expert assignment method to determine the weight of corresponding evaluation factor indicators,and take value evaluation results as guidance,and comprehensively evaluate according to the value of each unit Score and attribution analysis,the block context space unit is divided into three types of protection,control and renewal according to the three score intervals of "75-100 points","51-75 points" and "0-50 points".Finally,based on the protection concepts,principles and management and control tasks of contextual space units,a framework for the protection and control of contextual space units is formulated,and the protection and control path of the overall contextual space units of the block and the protection and control strategies of the three types of contextual space units are proposed.Several typical contextual space units put forward practical and implementable protection and control measures.Based on the identification,delimitation,and evaluation results of the contextual space units of the Barkhor Historic District,classify them based on value,and formulate protection and control paths and strategies from the block as a whole to each unit.The protection and control measures of various contextual space units that are regular and can continue the context of the block,take the contextual space unit as the entry point,cover all elements,and carry out overall protection more systematically,in order to provide certain protection for the protection of the Barkhor historical block.At the same time,it provides new ideas for the continuation and inheritance of the cultural context of other historical districts. |
