【摘要】 进入二十一世纪以来，天津的城市新区建设突飞猛进，历史文化街区的保护和改造也进入法制化轨道，城市风貌日新月异。同西方发达国家相比，我国的城市建设仍存在着发展方向的问题，历史文化街区的保护和改造也起步较晚，差距较大。我国已经进入城镇化高速发展的时期，如何使城市建设尽快步入科学发展轨道，成为城市规划学和建筑学以及城市管理者迫切需要解决的重要任务。本文从规划学和建筑学的视角出发，以历史研究为基础，以比较研究为方法，以理论与实践相结合为依据，对中西方城市的发展和改造的实践和理论进行纵向梳理与横向比较，并以天津历史文化街区的保护和改造为例，进而对我国当前城市发展的方向和策略，提出可行的考察和研究方法。论文的创新之处在于：从理论研究角度，重新对“城市聚落”和相关的“社会生态”概念进行定义和阐述，并以其为框架，重点阐述城市的本体与功能在时序性中的辨证运动；从历史研究角度，尝试借鉴通史类城市历史研究的体例，以城市规划和建筑学的视角，对中、外城市从古代、近代至现代的发展脉络进行纵向梳理，将城市聚落的时序性变化还原于史实中，对发展特点及其对后世的影响进行客观评述。从比较研究的角度，重点阐述城市本体和功能在历时、共时和未时等时序中的规定性，以及特殊城市聚落所表现的城市本体和功能的矛盾与冲突；从实践检验的角度，以天津历史文化街区的保护和改造为例，探讨天津历史文化街区的本体与功能在时序性中的辨证运动，总结城市改造的经验和教训。并以中新生态城为例，提出旧城改造的路径和我国城市应有的科学发展方向。从旧城改造的普遍性和高潮迭起的特殊现状中,能够看到我们的城市管理者和建设者关于传统与现代、历史与未来的认知理念上的变化。在对城市本体和功能的理性认知与传承创新中，建立新的城市发展理念，尽量缩小同发达国家之间的差距；尽快采取有效的应对策略，尽早使旧城改造和整个城市建设步入科学、人性的发展轨道，是本文的研究目的与研究意义所在。更多还原

【Abstract】 As Tianjin witnesses drastic development of new urban areas since the dawn ofthe21stcentury, the protection and alteration of historic/cultural sites go throughlegislation and the features of the city vary day by day. Nevertheless, comparisonswith developed countries in the west indicate that problems with respect to directionof development exist in urban construction of our nation and there are fairly big gapsin respect of the protection and alteration of historic/cultural sites due to latecommencement. During the stage of high-speed urbanization in our country, how toperform urban construction on a scientific basis as soon as possible becomes animportant task to be dealt with by researchers in urban planning and architecture andcity administrators.Based on historical studies, this thesis, from the perspective of city planning andarchitecture and in consideration of theory-practice combination, uses themethodology of comparative study to conduct chronological examination and crosscomparison of the practices and theories with regard to urban development andrenewal in China and the west and puts forward solutions feasible for the study andresearch on the targets and policies currently employed for urban development inChina with the protection and alteration of historic/cultural sites in Tianjin as anexample. Innovative ideas in this thesis include:In terms of theoretical studies, redefine and re-explicate urban settlement andthe relevant concept social ecology, against which the dialectical changes of thesubject and functions of city are detailed with respect to chronology;In terms of historical studies, try to chronologically examine the development ofChinese and foreign cities as of ancient times to modern and contemporary times fromthe perspective of city planning and architecture with reference to the practices forhistorical studies in respect of cities in the general history, reflect the chronologicalchanges of urban settlement in historical facts, and comment on an objective basis itsdevelopment features and the effects on posterity;In terms of comparative studies, focus on the prescriptive nature of the subjectand functions of city with respect to chronology such as diachrony and synchronicity; In terms of practical verification, take the protection and alteration ofhistoric/cultural sites in Tianjin as an example to discuss the dialectical changes of thesubject and functions of city with respect to chronology and summarize theexperience and lessons in urban renewal, and suggest the method for inner cityrenewal and the right direction towards scientific development of our cities with theSino-Singapore Eco-city as an example.From the universality of inner city renewal and the particularity of the currentextensive renewal activities, we can see the change in cognition&concepts of theurban administrators and builders on tradition vs. modernity and history vs. future.The purpose and significance of this thesis is to establish a new concept for urbandevelopment, minimize the gap between western countries and us during the sensiblecognition, inheritance and innovation of urban subject and functions, establish newurban development philosophy and adopt efficient countermeasures to cause innercity renewal and overall urban construction to be scientific and people-centered assoon as possible.更多还原
