China has 14 large coal bases, twelve of which are located in the northern region. After years of coal mining, the ecological vegetation of the coal bases has changed. This paper explores the spatial and temporal variation of fractional vegetation cover (FVC) in coal bases in northern China and identifies the trends and influencing factors of FVC using trend analysis, correlation analysis, statistical analysis, and dynamic coefficient method. The results show: Datong River basin of Qilian Mountain coal base is located in the alpine tundra, the FVC increased from 63.4% in 1998 to 69.77% in 2019, regionally FVC is mainly influenced by precipitation and temperature, and the mine area and its surroundings were mainly influenced by coal mining. The Chaibeiyuan coal base is located in the Gobi-desert region, and the FVC increased from 6.04% in 1998 to 9.78% in 2019, which is mainly influenced by temperature and precipitation, and the influence of coal mining is smaller and shorter. The Wulanmulun River basin of Shendong coal base is located in the transition zone of Loess Plateau and desert, and the FVC increased from 36.5% in 1996 to 51.45% in 2019, and the FVC mainly affected by coal mining, ecological protection measures, precipitation, and runoff. The Yanhe Spring area of Jindong coal base belongs to the northern karst area, and the FVC increases overall, from 50.0% in 1996 to 69.29% in 2021, which is jointly influenced by precipitation, coal seam burial conditions, ecological protection measures and the production and living of the densely populated area.
