Aiming at the problem of the response of vegetation dynamics to climate change,this paper studied the correlation of vegetation index and meteorological factors from small scale.Taking the MODIS normalized difference vegetation index(NDVI)data sets and monthly meteorological data from 2000to 2010in Ningxia as test data,the correlation between NDVI of different vegetation located 10km butter from the meteorological station and climatic factors was analyzed.The results as follows:NDVI of different vegetation in Ningxia remains on a growth trend from 2000to 2010;the extreme minimum temperature, maximum temperature,average temperature,average relative humidity and sunshine hours have obvious lag effect on vegetation growth in Ningxia;the correlation coefficient between NDVI and the extreme minimum temperature is the largest,followed by the average temperature;the correlation of NDVI and the extreme maximum temperature,the extreme minimum temperature and average temperature presents volatility increase from south to north;the correlation of NDVI and precipitation presents obvious decrease from south to north;in addition,the correlation between NDVI of cultivated land and meteorological factors is the biggest.
