摘　　要：目前,大气污染可视化系统多以二维、静态、数值的方式展示某一地区大气污染的严重程度。针对以上问题,基于Cesium平台设计了包括全球和全国两个尺度三维动态可视化系统。该系统采用B/S模式,在全球尺度下采用三维柱状图方式宏观展示全球各个国家的大气污染情况;在全国尺度下采用热力图方式具体展示每个省份不同的大气污染严重程度,并结合Echarts实现了连续、动态的三维可视化效果。从得到的可视化效果看出,该系统能够以三维、动态的形式在两个尺度下形象的展示大气污染浓度情况及变化趋势,具有一定的应用价值。At present,air pollution visualization systems are mostly two-dimensional,static,and numerically display the severity of air pollution in a certain area.In response to the above problems,based on the Cesium platform,a three-dimensional dynamic visualization system including the global and national scales is designed.The system adopts the B/S mode and uses a three-dimensional histogram method to macroscopically display the air pollution in various countries around the world at the global scale.Under the scale,the heat map method is used to specifically display the different severity of air pollution in each province,and combined with Echarts to achieve a continuous and dynamic three-dimensional visualization effect.It can be seen from the obtained visualization effect that the system can vividly display the air pollution concentration situation and change trend in a three-dimensional and dynamic form at two scales,which has certain application value.
