Urban design is becoming a hot topic in academic discussions and engineering practices in urban transformation of China.This paper systematically summarizes the historical development concerning urban design ideas and thoughts.On the basis of deep analysis,research,and judgment on development frontiers in urban design discipline and professional field in both China and abroad,the paper concludes that urban design has already experienced the development phases,including traditional urban design,modem urban design,and green urban design.Considering the new urban design development trend that is characterized by digitalization as the method and tool,it puts forward "digital urban design paradigm" as the fourth generation and sums up its five innovative values.The most important characteristic of urban design is "multi-scale experiential control of space in the whole chain," and digital urban design has greatly expanded the scale of such kind of experiential control.The relationships between the four generations of urban design paradigm are not simply successive,but inherited and partially iterative urban design "paradigm synthesis" under the joint effects of design objectives with difference in similarity,various spatial scales,and various social demands.Digital urban design not only possesses the social values and design originalities of man-machine dialogues,but also possesses quantitative properties and database outcomes,which can more effectively combine or even merge into the statutory urban planning system of China.Thereupon,it realizes the leapfrogging development in urban design based on systematical coordination.%城市设计正在成为中国城市转型发展中的学术探讨和工程实践热点.本文较为系统地梳理了城市设计思想理念的历史发展脉络,在深入分析研判国内外城市设计学科和专业领域发展前沿的基础上,认为城市设计已经历了传统城市设计、现代主义城市设计、绿色城市设计几个阶段的发展,目前已经呈现出以数字化为方法工具特征的城市设计发展新趋势,进而提出第四代“数字化城市设计范型”的学术主张并概括剖析了其五大创新价值.城市设计最重要的特征就是“多重尺度的全链空间体验性把握”,而数字化城市设计极大延伸了这种体验把握的尺度.城市设计四代范型之间并非简单的演替关系,而是在同中有异的设计目标、不同的空间尺度和不同的社会需求作用下的传承和部分迭代的城市设计“范型合体”.数字化城市设计不仅拥有人机对话的社会价值和设计创意,而且其拥有的量化属性和数据库成果,可以更有效地结合乃至融合到中国法定的城市规划体系中,进而实现城市设计基于系统协同的跨越式发展.
