基于地理信息系统的城市夜间光污染的可视化

The Visualization of Urban Light Pollution at Night Based on Geographic Information System

当前有关城市光污染研究多集中于光污染观测的理论方面,光污染的可视化也多是利用卫星图像进行处理分析,缺乏观测数据与可视化的结合。基于光污染具有空间地理信息的特征,本文探讨了城市夜间光污染与地理信息系统结合的方法,将观测数据进行光污染分布可视化表达,为未来光污染监测评价系统的建立提供理论与方法的支持。

Most researches on light pollution are focused on the light pollution observation theory,and the visualization of light pollution is mostly based on satellite image.However,it lacks combination of observation data with visualization.Based on the characteristics of light pollution with spatial geographic information,this paper studies the methods that combines night light pollution with the geographic information system,and marks the light pollution distribution visualization with the observed date.Thus,it can provide theory and method support for the future establishment of monitoring and evaluation system of light pollution,and it has an important guiding role in ecological city lighting.
