摘　　要：利用2018—2021年GOSAT上高光谱傅里叶变换光谱仪(FST)官方反演的大气CO_(2)浓度,采用自然相邻节点插值(Natural Neighbor)对GOSAT数据产品进行插值处理,获取黑龙江省各地市CO_(2)平均浓度,结合夜间灯光数据、火点数据和植被覆盖度数据,分析研究区域大气CO_(2)浓度时空分布规律、区域差异等特征,为发展低碳经济及环境治理提供参考。Atmospheric CO_(2) concentration officially retrieved by Hyperspectral Fourier Transform spectrometer(FST)on GOSAT in 2018—2021,Natural Neighbor interpolation is used to interpolate GOSAT data products to obtain the average CO_(2) concentration of cities in Heilongjiang province.In combination with night light data,fire point data and vegetation coverage data,analyze and study the spatial and temporal distribution of regional atmospheric CO_(2) concentration and regional differences,so as to provide reference for the development of low-carbon economy and environmental governance.

关 键 词：GOSAT卫星 CO_(2)浓度 植被覆盖度 火点 夜间灯光
