摘　　要：以工具变革为核心的第四代城市设计范型催生了众多数字化城市设计实践。本研究整合了数据支持、具身循证、算法驱动三个方向的计算性城市设计分析技术,并以上海小陆家嘴公共空间品质提升计划为例,展示了这一系统对中微观尺度城市设计的全方位、全流程的深入把控。数据支持的城市设计分析支撑基地问题识别和策略拟定;具身循证的城市设计帮助明确设计介入点及具体的空间设计要素;算法驱动的城市设计帮助预测方案成效并辅助方案优化。通过与传统方法对比及建成后指标预测,可以证明计算性城市设计方法的整合应用推动了城市设计的视角从“自上而下”向“自下而上”拓展,从二维向三维化、人本尺度转变。The fourth-generation urban design paradigm,with tool changes at its core,has given rise to numerous digital urban design practices.This study builds a computational urban design technology system integrating data-informed,evidence-based and algorithm-driven techniques.Taking the Little Lujiazui Public Space Quality Enhancement Project in Shanghai for example,this study demonstrates the support of this system for the overall urban design processes at the micro and medium scales.First,the data-informed urban design analysis technology is helpful for problem identification and strategy formulation.Second,the evidence-based urban design helps to select the design intervention point and control the specific spatial elements.Third,algorithm-driven helps to predict the effectiveness of solutions and assist in their optimization.Finally,it takes Shanghai’s Little Lujiazui leisure and business district renewal project as an example to rehearse the whole process of this technical system.By comparing with traditional methods and predicting indicators,the application of computational urban design methods has been proven to expand the perspective of urban design from the previous“top-down”perspective to the“bottom-up”one,emphasized embodied perception,and transformed from the two-dimensional to three-dimensional and human-oriented scale.
