Vegetation NDVI Change and Its Driving Factors in Guizhou Province in 2020
Exploring the monthly vegetation dynamic change and its influencing factors in Guizhou Province in 2020 is helpful to provide scientific basis for regional ecological environment restoration and management.Based on the monthly normalized difference vegetation index(NDVI)data in 2020,supplemented by meteorological data,correlation analysis and lag analysis,the temporal and spatial characteristics of vegetation change and its response mechanism to climate change in Guizhou Province were deeply analyzed.The results show that in 2020,the vegetation coverage of Guizhou Province is good,and the non-Karst areas are higher than the karst areas,among which the area with moderate coverage or above in the Karst area accounts for 46.78％of the province.NDVI in Guizhou Province showed a good correlation with rainfall and temperature in the same period,and the sensitivity of vegetation growth to temperature change was higher than that of precipitation change.The vegetation change in Guizhou Province in 2020 is greatly affected by climate change,and vegetation growth has a lag effect on precipitation,with a lag time of 1 month.
