Spatio-temporal Visualization Method of Spatial Interaction between Regions

摘要: 为解决现有区域间相互作用大小可视化结果缺乏可比性和受时间点限制的问题,提出了一种不受时间点限制的区域间相互作用的时空可视化方法.该方法以空间相互作用模型为基础,将区域中心点作为可视化结果的中心点,分别按区域受到的相互作用总量和与相邻区域间的相互作用计算可视化结果的半径和角度,实现了区域间相互作用的时空可视化.以四川省的7个地区为例,证实了该方法具有较强的可比性和易读性.Abstract: The existing visualization methods for spatial interaction between regions lack comparability and are limited by time points.In order to overcome these shortcomings,a spatio-temporal visualization method of spatial interaction between regions was proposed.In this method,the center point of every region is taken as the centre point of its visualization result,the total spatial interaction between regions and the spatial interaction between regions at different time points are calculated respectively to determine the radius and angle of visualization results by using the spatial interaction model.By taking the seven regions of Sichuan Province as research objects,the spatio-temporal visualization of spatial interaction between regions was realized.The experimental results show that this method is of high legibility and comparability.
