Spatio-Temporal Variation of Vegetation Coverage and its Response to Urbanization in Jilin Province, China from 2000 to 2020

Vegetation coverage is an important indicator of climate change and human activities. In the past 20 years, China has experienced rapid and intense urbanization. Using MODIS and nighttime light data, we investigated the spatiotemporal evolution characteristics of vegetation coverage and urbanization in Jilin Province during 2000-2020, and explored their relationship. Results showed: (1) The average vegetation coverage was decreasing at a rate of 0.05% /a.The spatial distribution was uneven, with an increasing trend in the western and central regions, and a significant decrease in the eastern region. (2) The FVC gradually increases from northwest to southeast. The highest FVC is concentrated in the eastern Changbai Mountain area. (3) There is a significant correlation between the evolution of vegetation coverage and urbanization, with an increase in vegetation and a slowdown in urbanization mainly concentrated in natural township areas, while areas dominated by decrease in vegetation are concentrated within urban areas.
