到2020年,中国许多城市将步入城市化中后期,面临向以居民活动为中心的城市空间功能组织方式转型的强烈诉求。以南京市为例,借助新浪微博获取海量签到数据,从居民活动这一社会化的视角,再探究旧有的城市空间功能组织方式。着眼于城市空间结构、土地使用、场所分布与居民活动的互塑关系,提出促使边界明确、分区功能相对单一的旧有规划方式向混合用地、功能灵活的社会规划转变的新思路。并基于小尺度的街区空间开展实际操作尝试,以期为城市规划中混合用地的类型组合、设施布局等方案拟订提供新的方法支撑与决策依据。
A number of Chinese cities will step into a later stage of urbanization by 2020, which implies a strong demand for restructuring the spatial and function- al pattern of cities with a focus on citizens' activities. Nanjing is selected as the case study area. With the help of massive registration data obtained from the Si- na microblog, this paper initiates further discussion on the old urban spatial and functional pattern with a socialized perspective of residents' activities and puts forward some new ideas in promoting social planning which stimulates mixed land use and multi-functional urban space. The propositions are tested at a neigh- borhood scale in two cases selected from Nanjing, with the hope of providing evi- dence base and technical solutions for decision-makings in relation to the combina- tion of different land use and the layout of facilities in urban planning.
