This study focuses on the architectural environmental color research of historical districts,taking the Dufudi Historic District in Wuhan City as a practical case.By employing digital intelligence technologies for color data collection,it analyzes and evaluates the current color status of buildings,facilities,and natural environments in historical districts.The research identifies existing issues in urban historical district color preservation,including lack of uniformity in color planning and deficiency in cultural connotations of color schemes.In response to these problems,the study formulates color palette ranges based on architectural typologies according to ancient building restoration principles and architectural heritage conservation principles.It proposes multiple schemes for adjusting overall facade lightness contrast and chroma,while comprehensively considering urban climatic conditions to determine the district's holistic color scheme.Adopting a district-level perspective,this research provides context-specific and time-responsive solutions for architectural environmental color preservation in historical districts from a relatively micro-level approach,offering adaptable pathways that align with regional characteristics and temporal variations.
Promoting community participation plays a crucial role in establishing a people-oriented community governance system.In the current wave of advancing smart community construction and enhancing the digitalization and intelligence of grassroots governance,it is of both theoretical and practical significance to explore whether smart community construction and intelligent device usage can facilitate resident participation.Existing studies have mainly focused on the definition,enabling mechanisms,and practical systems of smart community construction,with less emphasis on how it influences residents'community behaviors.This paper,based on the typical scenario of smart access control in smart community construction,conducted on-site questionnaire surveys in two smart communities in Beijing.It employed a structural equation model to analyze the impact mechanism of community intelligent device usage on residents'community participation.The results indicate that residents'usage of community intelligent devices significantly enhances community participation,with community trust playing an intermediary role,and residents'social connections leading to variations in the influence pathway.This study reveals the micro mechanisms through which smart community construction promotes resident community participation and highlights the importance of fostering community connections and organizations in smart community construction to achieve people-centered community governance more effectively.
With the continuous advancement of historical city protection and renewal work,it is urgent to construct a localized theoretical system and technical methods for the protection and renewal of Chinese historical cities.This article takes the Yulin Fangzhi City Map as the research object.Based on the local historical literature and on-site surveying and mapping of Yulin,by sorting and summarizing the relevant Fangzhi City Maps of Yulin,it studies the natural landscape pattern,cultural space creation,local eight scenic construction,and military defense system from four aspects,summarizes the development and evolution process of its city and the historical experience of planning and construction,Explore and propose practical strategies for application and inheritance in contemporary urban planning.
China's urban and rural planning industry is in the process of transforming from incremental planning to stock planning,but at present,there are certain deficiencies in the research object,theoretical system and practical operation of domestic stock planning research,so how to transform to enhance its effectiveness and scientificity is an important topic.From the perspective of cognitive psychology,this paper argues that the transformation of stock planning research needs to be based on the change of thinking mode,and the study of thinking mode change is also a favorable weapon to solve the above research deficiencies.This paper sorts out the four ways of thinking from incremental planning to stock planning,namely the expansion and deepening of the content of holistic,complex,value and process thinking mode,and discusses the transformation of the deficiencies of stock planning research on this basis.Among them,taking the historic district protection planning as an example in planning practice,it is believed that in the future,more attention should be paid to the function and finance balance based on the region,the research of multiple values of temporal and spatial isomorphism,the gradual mode of consultation combining the upper and lower levels,the phased classification promotion that respects financial resources,and the flexible system clause design.In order to provide reference suggestions for the research and development of stock planning,and promote the activation and utilization of stock resources.
Based on Baidu migration big data,this paper explores the role of digital economy development on urban resilience under the impact of the new crown epidemic in 2020 and its underlying mechanisms in 277 cities in China.The findings show that(1)the digital economy can improve urban resilience and promote the recovery of urban vitality,and this result still holds after the instrumental variables are selected.In addition,city characteristics such as economic and demographic characteristics also have significant effects on city resilience;(2)the results of mechanism testing show that technological innovation capability and government governance effectiveness are two important channels through which the digital economy empowers city resilience;(3)heterogeneity analysis reveals that different administrative levels,cooperation levels,and spatial development patterns of cities affect the effects of the digital economy.This paper enriches the research on the impact of digital economy development on urban resilience from the perspective of external shocks,and lays a factual foundation for the construction of digital China.
