Research On Micro-renovation Strategy Of Xuanhua Ancient City Based On Color Control

For a long time,there have been heated discussions on the protection of historical and cultural cities from all walks of life,and the two most representative extreme thoughts of "pure emphasis on protection" and "one-sided pursuit of development" have been in constant confrontation.The renewal mode of "micro transformation" aims to solve the contradiction between the protection of the ancient city and the development of the city,and becomes the "third way" to explore the protection of historical and cultural cities.Urban color has a long history as the city,and its value is far beyond the external beauty.It is not only a high cost-effective means to improve the city's appearance rapidly,but also an important overall role in cultivating and expressing the spirit of the city.How to look at history and think about the future from the perspective of modern people,and how to turn the heritage of ancestors into the wealth of future generations with the actions of modern people?This is a common problem in the field of urban renewal and urban color research.This paper chooses Xuanhua ancient city as the research object,which not only pays attention to the ontology of the ancient city,but also pays attention to the urban color that expresses the spirit of the city.It uses the method of empirical research to comb the current situation of Xuanhua ancient city in detail from the four aspects of cultural relics ontology,historical buildings,historical areas and built environment,and uses the method of data visual analysis to sort out the current situation of the research on the urban color of Xuanhua ancient city In order to lay a solid foundation for the research and analysis of Xuanhua ancient city's color,the necessity and feasibility of guiding micro transformation of urban color are interpreted.In order to avoid the influence of individual differences on the results of color vision,referring to the research method of "urban memory",this paper studies the cognitive subject and cognitive object of Xuanhua ancient city memory.By means of interview and questionnaire survey,data are collected and sorted out for quantitative analysis,and the final results are analyzed for cognitive coincidence,so as to get the urban color vision tendency of Xuanhua ancient city residents.In order to explore how to use the method of color control to provide the basis for the micro transformation of Xuanhua ancient city.Guided by the existing problems and taking the practice of regional transformation as an example,this paper systematically expounds the application method of "micro transformation" urban renewal mode under the framework of color control,and proposes to control three elements(lightness,hue,purity)and five relationships(lightness,hue,purity,area and location)of urban color in Xuanhua ancient city From the point of view of micro transformation,a new idea of "historical and cultural protection renovation" of Xuanhua ancient city is sought.
