Over the past thirty years，China has achieved tremendous urban development through a rapid process of urbanization，with the urbanization rate now reaching 67% approximately，creatinga remarkable achievement and grand panorama in thehistory ofworld urbanization.Meanwhile，since the launch of theHistoric Cities Conservation Program in 1982，a comprehensive conservation system has been established，covering historic cities，historic towns，traditional villages， industrial heritage，agricultural heritage，water irigation heritage，as well as intangible cultural heritage.Within historic cities，three levels of conservation have beeninstituted：historic urban areas，historic and cultural districts，and cultural relics and monuments.Consequently，a large number of cultural heritage sites of various scales have beenwell preserved，and the system for the conservation and inheritance of historic and cultural heritage has begun to take shape.

Although these achievements have been made，issues such as demolition and reconstruction continue to occur during the conservation and regeneration processes，resulting in the destruction of the overall fabric of old cities.The extensive development models that were only recently implemented during the period of rapid urbanization urgently require improvement， optimization，and even correction in the subsequent phases of urban regeneration.Following the rapid expansion of urban areas，greater attention and enhancement are critically needed for urban character， identity，and vitality.The integrationand synergyof the preservationand inheritance of historic and cultural heritage with improvement in urban space and the quality of urban lifealso require advancement toa higherlevel. These are fundamental theoretical issues of conservation and regeneration that call for in-depth exploration.As the scope and objects of historic city conservation continue to expand，and as the national urban development strategy shifts comprehensively from incremental expansion to stock-based urban regeneration，new situations and requirements for urban and rural development mustbe reviewed further，and new theoriesand methods for the conservation and regeneration of historic cities must be developed.This is also one of the essential foundations and core meanings of the cultural confidence strategy.

Cities，as the crystallization of human civilization，see their historic counterparts develop along a complete timeline of past，present，and future. This development represents an indivisible material accumulation and inherent causal relationships，where history and the future mutually influence each other， act as mirror images，and form an integrated whole.Consequently，exploring historic city conservation and regeneration requires balancing and unifying the dimensions of\"looking forward”and “looking backward.”\"Looking forward” encompasses respondingto the vision for medium-to-long-term socio-economic development， thereby contributing to the realization of Chinese modernization from an urban perspective.This also involves expanding the scope of conservation and regeneration of physical spatial forms to include the construction of intrinsic socio-economic drivers and mechanisms，continually broadening interdisciplinary relevance and inclusivity.Furthermore，it involves the application

中國在過去的三十年時間通過快速城鎮化進程實現了城市建設的巨大發展，城鎮化率今天達到約 67% ，創造了世界城市發展史上的奇跡和宏大圖景。與此同時，自1982年開啟的歷史文化名城保護事業，構建了涵蓋名城、名鎮、名村、工業遺產、農業遺產、水利灌溉遺產、非物質文化遺產等在內的完備保護體系，以及歷史文化名城中歷史城區、歷史文化街區和文物古跡的3個保護層級。各個尺度層級的一大批歷史文化遺產得到了較好的保護，歷史文化保護傳承體系初步建立。

在取得上述成績的同時，保護與更新過程中拆舊建新、老城整體肌理被破壞的情況屢有發生；在快速城鎮化時期剛完成不久的粗放型建設模式，也亟須在后續的城市更新中得到提升、優化甚至糾偏，城市風貌、城市特色和城市活力在城市規?？焖贁U張后亟待更強有力地得到關注和提升；歷史文化保護傳承與城市空間、城市生活品質提升，亟待實現更高層次的融合和相互促進一一保護與更新所面臨的深層次學理性問題亟待深入探討。隨著歷史城市保護范圍和保護對象的不斷擴大，在當前城市建設國家戰略從增量擴張全面轉向存量空間城市更新的背景下，城鄉發展的新形勢和新要求也需要進一步梳理，并構建歷史城市保護更新的新理論和新方法，這也是文化自信戰略的要義和基礎之一。

城市作為人類文明的結晶，歷史城市的發展建立在過去、現在和未來的完整時間軸上，是不可分割的物質層積和內在因果，歷史與未來相互影響、互為鏡像、共為一體。因此，歷史城市保護更新的探索，需要在“向前看”和“向后看”兩個維度實現平衡和統一?！跋蚯翱础奔劝ɑ貞鐣洕磥碇虚L期發展的愿景，從城市維度助力中國式現代化的實現；也包括從物質空間形態的保護更新，向社會經濟內在動力和機制的構建，跨學科的關聯性和包容性得到不斷擴展；還包括數字技術、 人工智能等新技術的應用，乃至因此對學科體系和行業發展的重構。 “向后著”則是站在新的歷史高度回望城市從誕生到不斷生長的原核、 內在基因和發展邏輯。在新技術不斷迭代的今天，從歷史城市保護視角 對我國從傳統城市形態通過近代化進程向現代性構建的再認識；重新錨 定“人”這一主體永恒的自然屬性和社會屬性。在多學科不斷豐富城鄉 規劃學科工具包的今天，應強化，甚至重新喚醒城鄉規劃及包括建筑 學、風景園林等在內的設計類學科內核，通過強化學科內核，構建多學 科參與的城鄉規劃和歷史城市保護更新理論、方法和實踐平臺。

ofnewtechnologiessuchasdigitaltechnologyand artificial intelligence，which consequently have the potential to transform discipline systems and industry development.“Looking backward，\"on the other hand，involvesre-examining，from anewhistoric vantage point，the city's origins，inherent DNA，and developmental logic from its inception through its continuous growth.Inan era of rapidly evolving technologies，this requires a re-understanding of China's urban transformation from traditional forms through modernization toward the construction of modernity from the perspective of historic city conservation. It also means re-anchoring the“human” element，with its eternal natural and social attributes，as the central subject.Today， as multiple disciplines continuously enrich the toolkit of urban and rural planning， it is crucial to strengthen and even reawaken the core of urban and rural planning and design-related disciplines，includingarchitecture and landscape architecture.By reinforcing thisdisciplinarycore，amultidisciplinaryplatformcan beconstructed forthe theory，methodology，and practice of urban and rural planning and historic cityconservationand regeneration.

Onthe occasion of the revamp of Urban Design，its first issue of2025 focuses on historic city conservation and regeneration.This serves to reaffirm theleading role of the national strategy for protectingand transmiting historic and cultural heritage in urban planning and construction，as well as its critical supporting function within the discipline system of human settlements.The aim isto help future urban development clearly discernits historic trajectory and solidify thecultural foundations forhigh-qualitydevelopment.Concurrently， the issueseeks to demonstrate that the academic logic of historic conservation and urban design as“two sides of the same coin.”This involves creatively achieving， in the new era，historic and cultural heritagepreservation ata higher level from amore fundamental source with renewed methodologies.It also endeavors to unearth more traditional construction wisdom for future urban construction and urbanregeneration，therebyofferingbeneficial explorationsforthepreservation andinheritance ofhistoric and cultural heritageand its further development and flourishing.To thisend，the15articlesin this issue are dividedinto four main sections：（l） tracing the history of historic and cultural heritage preservation in China and worldwide to establish the historical and theoretical foundations for historic city conservation and regeneration;（2） exploring the scholarly implications ofexcavating historicculture from morphological， typological，and architectural perspectives，and defining，froma disciplinary standpoint，the material spatial carriersof\"urban memory”and their constituent elements;（3） investigatingdesign thinking，concepts，and methods in historic and cultural heritage preservation from the perspectives of practice， teaching，and international outlooks，and seeking integrated pathways for historic conservation and urban regeneration; （4） taking cities such as Guangzhou， Chongqing，Nanjing，and Quanzhou as examples to conduct planning and design explorations focused on historic city conservation and regeneration at various scales，including famous historic cities and districts.

Inthe first section，which traces the history and theory of historic and cultural heritage preservation，the article of Xu Subin's team， The Process of China's Cultural Heritage Conservation Planning from the Perspective of Participants， isa specialized outcome of a major National Social Science Fund project.It presents a panoramic overview of China's historic and cultural heritage protection and inheritance from 1949 to 2023 and outlines the“overall developmental trajectory.”While manyarticlesreviewthe historyof cultural heritageand famous historic city conservation， this paper specifically focuses on three developmental threads：cultural relics，famoushistoric and cultural cities，and world cultural heritage.Through extensive documentary and historic materials，it reconstructs a comprehensive，rich，and robust account of the historic context and inherent logic ofChina's heritage preservation efforts.Furthermore， from the unique perspective of participants' individual memories，it showcases the arduous journey of China's heritage conservation，urban conservation，and the preservation and inheritance of Chinese culture.The article delineates the close connectionswith international conservation experience，such as the Venice Charter，as well as with representative Chinese policy documents and exemplary conservation practices.Thiscontribution has significant academic value in terms of understanding the true meaning of

在歷史文化保護歷程和理論回溯的第一板塊，徐蘇斌團隊《親歷者視角下中國文化遺產保護規劃進程》作為國家社科基金重大項目的專題成果之一，全景式呈現了建國后從1949年到2023年的我國歷史文化保護傳承的“整體發展脈絡”，盡管梳理歷史文化遺產和名城保護歷史文章眾多，但該文重點從文物、歷史文化名城和世界文化遺產3條發展線索，通過大量文獻史料再次構建了全面、豐富和堅實的我國歷史文化保護歷程場景和內在邏輯，更從親歷者個體記憶這一獨特視角，展現我國遺產保護、城市保護乃至中華文化保護傳承這一篳路藍縷歷程，梳理了與《威尼斯憲章》等國際保護經驗、與我國代表性政策文件和范例保護實踐的緊密關聯性，對于認知當前歷史文化保護傳承重要理念的真實內紀念性建筑更具有形態學意義，也蘊含更深層次的“城市記憶”特質，李 昊團隊《層積共生：居住型歷史街區遺產價值辨識——以西安明城區回 坊片區為例》從原住民日常生活的“活態遺產”視角，關注居住型歷史 街區的遺產價值，揭示了長時段歷時性層積形成的“物質層積、文化演 進與社會互動的共生特征”，對于從非物質文化的“活態傳承性”視 角，去認識基于原住民日常的“歷史真實性”和社區在連續性演變中的 文化基因保護與傳承，進而對建成遺產和歷史街區的理論發展，都具有 一定的參考意義。同樣聚焦于居住形態研究，張杰、黃鶴、孫詩萌團隊 《北京居住小區類歷史建筑的特征、現狀及保護挑戰》展示了建筑尺度 上堅實的歷史建筑史論方法及其研究成果，通過原始圖紙分析、歷史文 獻梳理、實地調研比對、關鍵人物訪談、遙感影像識別等多元研究方 法，對北京近代居住小區類歷史建筑涉及的22個小區、285棟單體開展 類型學、空間布局和形式風格等多維度研究，凝練了遺產價值，更呈現 了北京近現代住宅的全景譜系和首都住宅建設的時代成就。

key contemporary concepts in historic and cultural heritage conservation andinheritance，and discerningthe future directionof their development.

Europeisthecradle ofmanyseminal ideasintheconservationofhistoric monumentsand cities.In Conservation ofHistoric Centers and the CreationofArt Cities，ZhangSonguses the conservationofhistoric centers in Italy asa guiding thread toreview and analyze the pioneering conservation practices of Gustavo Giovannoni andthe AACAR（Associazione Artistica fraiCultoridi Architettura）.Thearticle reveals the theoretical and practical evolutionofhistoric preservation，shiftingthe focus from individual monuments to the entire urban fabric.It also explores the relationship between theoretical research and design practice.Through an examination of the genesisof a series of international chartersand academic institutionssuchas ICOMOS， thearticle investigates the intrinsicmechanismsof historic and cultural heritage preservation.These findingsprovide valuable international referencesand theoretical support for China's “Beautiful China”initiative，which aims to promote cultural prosperity and comprehensive socio-economicrevitalization.

InAPreliminary StudyontheConservation ofFamousHistoric Citiesand Sustainable Development in the Eraof Urban Agglomerations，DongWeiadopts amacro-historic perspective to expand the scope of historic and cultural heritage conservation and inheritance to encompass broader urban agglomerations.Based onthe concept ofcity-environment integration and the development trendsof China'surban agglomerations and metropolitan areas，and by excavating traditional wisdom from historic maps，the article proposes the concept of“famous historic city clusters.”While revealing the historic and cultural connectionsof ancient cities andcity regionswith these famous historic cityclusters，italso offers solutions for the conservation of famous historic cities to support people-centered urban development and Chinese modernization in the new era.

Preserving“urbanmemory”isa keyarticulationof thecurrent goals in historicand cultural heritage conservation and inheritance.It bridges disciplinary expertisewith policyorientationand public perception.Defining“urbanmemory’ hasbecome a crucial question that needs to be addressed in the field of historic cityconservation and regeneration today.The value of this exploration is directly manifested in transcending the often superficial concept of architectural style prevalent in historic and cultural heritage conservation，thereby establishing an academic foundation for the conservation and inheritance of the deeper spatial morphological core.The four articles in the second section explore“urban memory” across different scales and temporal dimensions，from humanistic landscapesto historic buildings，and from Chinese traditions to urban modernization.Widely distributed local cities，particularlycounty-level ones，embody the universal connotations of China's traditional construction wisdom.InA Preliminary Study on theMorphological Patterns and Mechanisms ofAncient Prefectural and County Cities in Huizhou Based on Three Influencing Factors，Zhong Ge’s team adopts the perspective of traditional prefectural and county cities.Through a holistic and comparative study of“one prefecture and six counties”in Huizhou， and by employing morphological typology and historic map transliteration methods， theresearch excavates the wisdom of local urban construction.It extractsand clearly presents three influencing factors from the urban construction processnatural geography，socio-economics，and cultural-ritual systems—along with their mechanisms in shaping the overall pattern and spatial form of historic cities.The data and diagrams from thisprefectural and county perspective hold significant historical value for enriching research on traditional Huizhou human settlements.Similarly employing historic mapsand theoriesand methodsof urban morphology，ZouHan'steam，inAStudyontheEvolutionofHankou'sUrban Formunder the Influence ofModernRailways，takes the typicallymodernized city ofHankou as an example.The study explores railways，a symbolic element ofthe Industrial Revolution，and the mechanisms through which they influenced the evolution of Hankou's urban form during its modernization process via factors such as changes in external transportation methods，industrial space development，and road system expansion.This offers a valuable reference for observingthe transformationofChinesecities from traditional formsto modern cities and the construction of urban modernity.Residential spaces and patterns

整體性保護是歷史文化保護領域的核心原則之一，是貫穿文物古 跡一歷史街區一歷史城區等各種類型、多個尺度層次歷史文化遺產保 護的普適價值，也是構建歷史保護和城市設計一體性的橋梁。第三板 塊的4篇文章分別從實踐、海外經驗和設計教學3個不同視角探討了歷 史文化保護和城市更新中的城市設計方法和整體性建構。鞠德東《歷 史文化保護中的城市設計方法融合與應用實踐》以歷史文化保護與城 市設計的一體性為切人點和價值導向，依托參與和積累的大量名城保 護實踐案例，從城市、街區和建筑3個尺度層次，探討了名城保護中 城市設計運用的理念、方法和策略，并在閬中古城、周口沙南歷史文 化街區兩個重要規劃設計案例中加以呈現。尹牽懿《設計引導舊城區 激活——英國城市更新中的設計干預》通過大量原始文獻的收集和 整理，詳細介紹了英國城市更新中設計干預（designintervention） 的社會經濟背景、發展歷程和主要內容，分析了設計干預的有效性和 局限性，及其對我國老城區城市更新和激活的啟示。鐘舸團隊《基于 歷史文化挖掘和城市形態認知的北京老城文脈保護傳承及城市設計方 法研究—一以宣南菜市口片區為例》是基于研究生城市設計課程的延 伸研究成果，通過片區歷史空間演變歷程梳理與文化內涵特征挖掘， 針對歷史城市現代化過程中典型的空間形態碎片化和拼貼現象，構建 了“城市一片區一街區”的多層次城市空間形態認知方法，并提出基 于“不變”與“變”理念的歷史文化保護傳承策略和基于人群活動空間的動態整體性策略。同樣聚焦城市空間形態類型的設計教學研究， 蔡永潔團隊《從“馬路”到“大街小巷”一一上海新江灣城空間重塑 教學實驗》繼承了團隊持續多年的新城“再造實驗”探索，將快速城 鎮化時期的新城建設納人城市更新的觀察視角，體現了城市連續性迭 代演變的歷史觀念。該研究剖析了新城大型居住街區的城市性和街道 活力缺失現象，基于“細胞壁重塑”理念，跨城市和建筑尺度提出了 “大街小巷”的空間重塑設計策略。

Focusingon the heritagevalueof residential historic blocks，it revealsthe“symbiotic characteristicsofmaterial accumulation，cultural evolution，and social interaction” formed through long-term， diachronic accumulation.This research is of reference significance forunderstanding“historicauthenticity”based onresidents'dailylives and the conservation and inheritance ofcultural DNA in the continuous evolution of communities from the perspectiveof the“living inheritance”of intangibleculture， andconsequently，forthe theoreticaldevelopmentof built heritageandhistoric districts.Also focusing on residential morphology research， the team of Zhang Jie， HuangHe，and Sun Shimeng，in Characteristics，Current Status，and Preservation Challenges ofHistoric Residential Complexes in Beijing，demonstratesrobust historic architectural theory methodsand their research outcomesat the building scale.Through diverse research methodsincluding original drawing analysis， historic literature review，on-site survey comparisons，key figure interviews，and remote sensing image identification， they conduct multi-dimensional research on22complexes and 285 individual buildingswithinBeijing'smodern historic residential complexes，which covers typology， spatial layout，and formal style.The studyrefines their heritagevalue and， moreover，presentsapanoramic spectrum ofBeijing'smodern and contemporary housing，aswell as the achievements of housing construction in the capital during that era.

Holistic preservation is one of the core principles in the field of historic and cultural heritage conservation. It representsa universal value that permeates the conservation of various types and multiple scales of historic and cultural heritageincludingcultural relicsand historicsites，historic blocks，and historic urbanareasand also serves as a bridge for constructing the integration of historic conservation and urban design.The fourarticles in the third section explore urban design methods and holistic constructionin historic and cultural heritage conservation and urban regeneration from three different perspectives：practice，overseas experience，and design education.Ju Dedong，in Integrationand Application Practices of Urban DesignMethodsinHistoricand Cultural HeritageConservation，takesthe integration of historic and cultural heritage conservation and urban design as the entry point and value orientation.Drawing on extensive practical cases of famous historic city conservationthathe hasparticipated inand accumulated，thearticle discusses the concepts，methods，and strategies of urban design application in famous historic city conservationat three scales：city，block，and building.These are presented through two significant planning and design cases： Langzhong AncientCityand the ShananHistoricand Cultural Blockin Zhoukou.Yin Luoyi， in Design-Led Activation of Old Urban Areas—Design Intervention in BritishUrbanRegeneration，providesadetailed account of thesocio-economic background， development process，and main content of design intervention in British urban regeneration，based on the collectionand organization of extensive original literature.The article analyzes the effectivenessand limitationsof design intervention，aswell as its implications for the urban regeneration and revitalizationofoldurbanareasin China.ZhongGe'steam，inResearch on theConservation and Inheritance ofBeijing's Old City Cultural Context and Urban Design Methods Based on Historic and Cultural Excavation and Urban Morphology Cognition—A Case Study of the Xuannan Caishikou Area， presents extended research findingsbased onapostgraduate urban design course.By reviewing the historic spatial evolution process and excavating the cultural connotations and characteristics of the area，and addressing the typical phenomena of spatial morphological fragmentation and collage in themodernization process of historic cities，the study constructs a multilevel cognitive method for urban spatial morphology （city-precinct-block）. It also proposes strategies for historic and cultural heritage conservation and inheritance based onthe conceptsof“permanence”and“change，”aswellasa dynamic holistic strategy based on human activity spaces.
