摘　　要：大同煤田因多年的开采历史,破坏了农林草地,成为生态环境脆弱区,导致煤田区域碳循环变化。由于近几年的绿色发展,生态环境有所改观,碳汇量随之增加。本文以大同煤田为研究区域,基于2020和2021年珠海一号高光谱遥感影像数据,从土地利用变化角度研究煤田区域两年的碳汇变化情况,结论如下:(1)大同煤田区域两年间土地利用结构未发生显著变化,草地、林地和耕地分别增加了2.57、0.71和0.11 km^(2);(2)2021年较2020年大同煤田碳汇量增加了3万t CO_(2),煤田生态环境逐渐改善。Due to the mining history of Datong coal field for many years,it has destroyed the agriculture,forestry and grassland,and become a fragile ecological environment area,resulting in the change of carbon cycle in the coal field area.With the green development in recent years,the ecological environment has improved,and the carbon sink has increased.Taking Datong coal field as the research area,based on the hyperspectral remote sensing image data of Zhuhai No.1 in 2020 and 2021,this paper studies the carbon sink change in the coal field area in the two years from the perspective of land use change.The conclusions are as follows:①the land use structure of Datong coal field area has not changed significantly in the two years,and the grassland,forest land and cultivated land have increased by 2.57 km^(2),0.71 km^(2) and 0.11 km^(2) respectively;②the carbon sink of Datong coal field in 2021 has increased by 30000 t CO_(2) compared with that in 2020.The ecological environment of the coal field has gradually improved.
