Because of the advantage of long time series of GIMMS NDVI,the datasets are used to study the characteristics of vegetation widely.In this study,dataset from 1982 to 2012 were used to analyze the temporal and spatial changes of NDVI in China,and the bivariate and partial correlation between NDVI and climatic factors(precipitation,average temperature,average wind velocity,average vapour pressure,mean relative humidity and sunshine duration)in different vegetation types.The results showed that the change of NDVI was significant within a year,and the minimum and maximum values appeared in late February and early August,respectively.The increasing trend of NDVI was observed from 1982 to 2012,and the annual increasing rate was 0.0003.The correlation between NDVI and climatic factors was different due to various vegetation types.Generally,NDVI had the positive correlation with precipitation,average temperature,average vapour pressure and mean relative humidity,and showed negative correlation with average wind velocity and sunshine duration.
