Abstract: The spatial correlation between intra-annual and inter-annual variation of the vegetation cover and climate change in the Changbai Mountain Area was analyzed by using the HANTS, imagery processing and pixels-based spatial statistical methods based on the MODIS-NDVI data from 2000 to 2008.The results showed that, the temperature and the precipitation in this area showed an increasing trend in recent 10 years. During intra-annual and inter-annual variation, the influence degree of temperature on the vegetation cover was higher than precipitation, and there was a positive correlation between the temperature and the vegetation cover in spring and autumn but negative correlation in summer. The statistics of monthly would reflect more detail response relation between the vegetation cover and climate change.
