摘　　要：城市发展过程中往往会出现城市照明光污染加重的现象,通过卫星影像手段进行宏观层面的问题发现及相关管控政策制定具有重要意义。基于团队已有研究,进一步通过R语言量化方法分析我国4座城市的光污染地图演变特征,结果显示:城市边界不断向外扩展的城市光污染范围会同步增大;城市与周边区县联系的加强会直接反映在卫星影像中;机场体现出长期高污染特征;较大规模的城市建设会引发明显的光污染;光污染边界不断向海域、山体等周边区域扩散现象明显。研究进一步验证了通过卫星影像手段分析城市照明光污染的演变特征具有可行性,并针对城市宏观层面的光污染分析提出建议,为后续更为深入的评估工作提供参考。In the process of urban development,the light pollution of urban lighting is often aggravated.It is of great significance to carry out macro level research through satellite images.Based on the team’s existing research,we further analyzed the evolution characteristics of light pollution maps of 4 cities in China through the R language quantitative method.The results show that the urban light pollution range will increase synchronously as the urban boundaries continue to expand outward;The strengthening of the connection between the city and the surrounding districts and counties will be directly reflected in satellite images;The airport is characterized by long-term high pollution intensity;Large scale urban construction will cause obvious light pollution;It is obvious that the light pollution boundary continues to spread to the surrounding areas such as sea areas and mountains.The study further verified the feasibility of analyzing the evolution characteristics of urban lighting light pollution by means of satellite images,and put forward suggestions for light pollution assessment at the macro level of the city,so as to provide reference for more in-depth assessment in the future.
