本文从城市特性研究的角度出发，梳理并分析了上世纪二十年代起至当下的城市理论与城市现象，并从中提取出各时代中不断演变的“城市性”，尤其关注现代城市主义与新城市主义两个关键节点，即后者对前者的批判与继承。进而，在当下后疫情时代的背景下，对原有的城市性进行再批判，并结合当下中国城市的三重危机，即远期的硅基空间的冲击、中期的城市人文属性的缺失与近期的后疫情时代的商业空间萧条，初步提出了后疫情时代的“新城市性”宣言三点：硅碳空间合基性、硬-软-湿件体系综合性、空间内容丰盛性。之后，首先本文通过互联网社交媒体平台进行的“城市魅力空间研究”来阐明硅碳合基性的具体城市体现，并总结相应的九大象限设计方法论；其次从装置、建筑、街区三种尺度，分别研究了中国当下的人文城市案例，并总结出相应的各尺度设计方法营造硬件-软件-湿件相综合的城市体系；再次以檀谷商业空间中的慢闪公园建设实践为例，具体阐明了空间内容丰盛性中内容对空间的主导及空间对内容的承载与促进作用。最终将提炼出的后疫情时代的“新城市性”及其设计方法，应用到檀谷D1地块的空间设计之中。完成“随身携带的超城市”项目设计。

From the perspective of urbanity research, this paper composes and analyzes urban theories and phenomena from the 1920s to the present, and extracts the evolving "urbanity" in each era, paying particular attention to the two key points of modern urbanism and new urbanism, and the latter‘s critique and inheritance of the former. Further, in the context of the current post-pandemic era, the original urbanity above-mentioned is re-critiqued, and with the analysis of triple crisis of Chinese cities -- the impact of silicon-based space in the long term, the lack of humanistic attributes in the medium term, and the depression of commercial space in the recent post-pandemic era -- three points of the manifesto of "new urbanity" in the post-pandemic era are then proposed, which include Silicon-Carbon Based Space, Comprehensive Hard-Soft-Wetware System, and Spatial Content Abundance. After that, in the fourth chapter, this paper then firstly clarifies the specific urban embodiment of the silicon-carbon based space through the "urban charming space study" conducted through the Internet social media platforms, and summarizes the corresponding nine quadrants of design methodology; secondly, the fifth chapter studies the current humanistic city cases in China from three scales: installation, architecture and neighborhood, and summarizes the corresponding design methods of each scale to create an integrated hardware-software-wetware urban system; thirdly, the Moofland Park construction practice in commercial space of Tanko Valley in Beijing is used as an example to clarify the dominance of content on space and the role of space in carrying and promoting content. Finally, the distilled "new urbanity" and its design methods in the post-pandemic era are applied to the spatial design of D1 site in Tanko Valley, Beijing. The design of the project is completed with the concept of "Hyper City Pocket".
