遥感技术在城市夜间光污染研究中的应用进展

Application of Remote Sensing Technology in the Study of Urban Night Light Pollution

遥感数据具有辐射范围广、时间序列长、准确度高等优点,它为城市光污染强度及其时空分析提供条件,受到城市夜间光污染研究人员的青睐。根据遥感数据类型进行分类,分别针对美国国防气象卫星DMSP/OLS、可见光红外成像辐射仪VIIRS、以色列卫星EROS-B提供的夜间灯光数据及美国国家航空和宇宙航行局的陆地卫星Landsat提供的土地利用数据,对应用成果中遥感数据基本信息、技术方法、研究应用以及应用优缺点进行述评,统计了遥感数据在光污染研究领域的应用现状,总结出遥感数据应用的限制及发展前景。

Remote Sensing (RS) data has wide radiation range, long time series, high accuracy. It provides the convenience for urban nighttime light pollution intensity and space-time analysis, therefore it is widely favored by the research scholars. At present, there are many researches related to light pollution using RS data, but few studies have reviewed and summarized the researches. Therefore, this paper analyzed and compared existing research and classified the researches based on RS data types. Respectively for the nighttime light data provided by the US National DMSP/OLS (Defence Meteorological Satellite Program/Operational Linescan System), VIIRS (Visible Infrared Imaging Radiometer Suite), Israeli satellite EROS-B and the land-use data provided by the US NASA (National Aeronautics and Space Administration) Landsat, this paper combed the basic information, technical methods, research applications and advantages & disadvantages of RS date in existing researches, concluded the current status of application in nighttime light pollution, and finally summarized the application limitations and development prospects of remote sensing data.
