基于城市大数据的城市数据画像构建

Construction of City Profile Based on Urban Big Data

[目的/意义]解决城市发展中遇到的诸多问题,提升城市治理与运行能力、打破城市发展困境。[方法/过程]从三元世界理论在城市空间的映射,将城市空间认知解构为物理空间、社会空间和信息空间,以城市运行过程中产生的大数据资源为基础,将用户画像的理念映射到城市环境中,提出城市数据画像的构建路径。结合智慧城市和城市竞争力相关研究,构建城市数据画像分面模型,并进行时空透视。以城市交通画像为例,介绍城市数据画像的应用模式。[结果/结论]借助城市数据画像,能够全景化呈现城市运行状况,以智慧数据辅助城市治理、运行、发展,实现智能化城市信息服务。

[Purpose/Significance]To solve problems encountered in urban development,improve urban governance and operational capabilities,and break the dilemma in urban development.[Method/Process] From the mapping of ternary world theory into urban space,urban spatial cognition was deconstructed into physical space,social space and cyber space.Based on the big data resources generated during urban operation,the concept of user profile was fitted into the urban environment and proposed the construction path of urban data profile.Combining the research on smart city and city competitiveness,we constructed a city data profile facet model and conduct time and space perspective.Taking the urban traffic profile as an example,the application mode of urban data profile was introduced.[Results/Conclusions]With the help of urban data profile,it is possible to provide a panoramic view of the city s operational status,and to assist urban governance,operation,development,and intelligent urban information services with smart data.
