本文主要介绍了以时间为导向的设计理论—“时—空”城市规划设计法—在分析和改善公共空间与都市服务领域的最新成果。在“时—空”城市规划设计法领域,公共空间的可达性和都市服务的有效性共同对设计提出了整合性的要求—实体的公共空间的设计和居民日常生活城市管理的高度整合。城市的空间品质不仅反映在开放空间的数量,更体现于建筑环境在时间与空间双向维度的可达性和有效服务性上。这包括公共和私人空间之间的各种关系,并需要考虑居民和城市使用者的多样性,如他们的身体情况、性别、年龄、社会和经济条件、生活背景、种族等的差异。在具体实践项目中,关于意大利波河流域的线性大都市系统的时间图示化地图、基础性指标与大数据集共同组成的系统旨在探索并阐释如下问题—在当代城市中,临时人口和常住居民的关系、居住城镇体系的时空形态、都市可达性以及邻近性的概念。 This paper mainly introduces the time-oriented design theory - “hour-space” urban planning and design method - the latest achievements in analyzing and improving the public space and urban services. In the “time-space” urban planning and design method, the accessibility of public spaces and the effectiveness of urban services jointly put forward an integrated requirement for design - the design of physical public spaces and the height of urban management of residents’ daily lives Integration. The quality of the city’s space is not only reflected in the number of open spaces, but also reflected in the reachability and effective service of the building environment in both the time and space dimensions. This includes relationships between public and private spaces and takes into account the diversity of inhabitants and urban users, such as their physical condition, gender, age, social and economic conditions, life background, race, etc. In practice, a system of time-based maps, basic indicators and big data sets of linear metropolitan systems in Italy’s Po River basin aims to explore and explain the following issues - in contemporary cities, the temporary population and The relationship between resident residents, the spatial and temporal patterns of living urban systems, the urban accessibility and the concept of proximity.
