From: Divergent changes in the elevational gradient of vegetation activities over the last 30 years
The elevational gradient (EG) of climate and human activity variables. a The spatial pattern of the EG of mean annual temperature (EGtem). b The spatial pattern of the EG of total precipitation (EGpre). c The spatial pattern of the EG of population density (EGpd). d The spatial pattern of the EG of night light index (EGNLI). A frequency distribution of the EG values is shown in the inset at the bottom-left for each panel. Regions marked with dots have statistically significant (p < 0.05 with the F-test) EG values
