Correlation between urbanization and vegetation cover in China and analysis of its influencing factors

ABSTRACT

There are spatial differences in the correlation between urbanization (NL) and vegetation cover (NDVI), and the driving mechanism is not clear. This study aims to explore the spatial correlation between NL and NDVI in China and identify the influencing factors. The results showed that there was a north-south difference in the correlation, and this correlation was strongest in winter. Meteorological factors were the main influencing factors, Bivariate enhancement is observed for TEM-DEM at the national scale in winter, TEM-relative humidity (RH) in cold spot areas, and TEM-RH in hot spot areas in summer.
