A Study Of Ganzhou Urban Activity Space Based On Multivariate Data

For a long time,the lack of spatio-temporal behavior data based on individual level and the difficulty of its collection have become a major obstacle to the study of human and spatial interaction and its laws.With the advent of big data boom,the popularity of SOLOMO,the progress of ICT,accelerated the spatio-temporal exchange of knowledge,technology,talent and capital.Time,space and their relationship will be changed,space of flows will become the main carrier of region,urban and residential activities and will be represented through a large number of complex network or the big data of mobile information device.It provides an unprecedented opportunity for spatio-temporal behavior study.In the empirical study,firstly,this paper analyzes the spatial distribution law of POI points by using the POI data of Gaode map,thus defines the boundary of the residents' activity space,and preliminarily determines the structural characteristics of the activity space.With the establishment of the grid under the fine scale,the quantitative analysis of the urban land mixed degree is provided under the model of land use equilibrium extent,which provides a useful reference for exploring the relationship between the distribution of facilities and the mixed degree of land use and the activity space.Then,through the catering and leisure business data of dianping.com to build the reputation of the evaluation index system,based on individual behavior data,analyzes the consumption space characteristics and distribution.And then,by Sina Weibo sign-in data,comprehensive analyzes the rule of residents activities of the time,the general characteristics of urban activity space and its spatio-temporal variations,and through the ROSTCM6 semantic mining system to identify the spatial distribution of different emotions to preliminary evaluation of the built environment.Finally,this paper summarizes the main conclusions of the study and compares the new research method with the traditional one to find out their advantages and disadvantages,which provides a useful reference for a more comprehensive and in-depth study on urban activity space and the impact of ICT on urban space in the future.In the theoretical analysis,this paper based on the perspective of space production theory,combined with the previous analysis and typical cases,analyzed the space production of new district with the promotion of consumption space,space reproduction of urban renewal with the stimulation of cultural and creative industries and the logic and mechanism behind them.
