信息过载导致的公共健康问题在后疫情时代不断加强，高密度城市历史城区体现尤为明显。研究对高密度城市信息过载问题进行分析，提出研究假设：是否可通过营造具有康养功能的城市历史景观传达有序健康的历史环境信息，提供应对高密度城市信息过载问题的景观服务框架下的调节与文化服务，来缓解高密度城市信息过载现象所引发的公共健康问题。并以西湖路广场口袋公园更新设计为实践研究案例，引用积极健康的概念与维度，将信息传递和公共健康进行关联，基于“天地人”相对应的“遵生营境”“画意营境”“正念入境”三种设计手法，探讨风景园林介入城市更新的创新型途径。

With the development of the information age, the public health problems caused by information overload have been increased in the post-epidemic era. This phenomenon is especially obvious in the high-density historical urban areas. This research first analyzes the information overload in high-density cities. At the same time, the research hypothesis,is it possible to alleviate the public health problems arising from the phenomenon of information overload in high-density cities by creating historic urban landscapes with health functions that convey information about an orderly and healthy historic environment, and by providing regulation and cultural services within the framework of landscape services that respond to the problem of information overload in high-density cities. Taking the renewal design of Xihu Road Square as a practical research case, this research cites the concept and dimension of "positive health", associates information transmission with public health, discusses embodiment and application of the three design methods of “Landscape Design with health cultivation”, “ArtisticConception-Based Jing-Structure”,and “Create Environment to provide Mindfulness Therapy Activities” that corresponding to heaven, earth and people in the gardening health care functions of the current landscape design.
