Vegetation coverage (VC) is usually used to judge the growth status of plants and monitor the quality of the ecological environment. To better understand the dynamics and processes of VC change in urbanized cities, this research studied the impact of common natural and human factors on VC in Beijing, China from 2000 to 2015. The results showed that in Beijing, China, VC decreased by 0.1534% per year from 2000 to 2015. VC was low at an altitude range of -129~200 m and a slope range of 5~10°.

Urbanization represented by the brightness of night light had a negative impact on VC. The negative correlation between urbanization and the VC was observed mainly in the most urbanized area. From 2000 to 2015, the area of construction land increased by 1784 km 2 . Between 2000 and 2015, the land use changing from waters to grassland increased the VC by 24.72%, and the land use changing from farmland to construction land decreased the VC by 17.82%. This research can provide scientific support for local policy-making to improve the urban ecological environment.
