The spatial distribution and dynamic changes of vegetation in Shaanxi Province were analyzed using SPOTVEGETATION data for recent ten years.The NDVI values of different regions including the southern

Guanzhongand the northern areas were compared in regard to annual and monthly variations.It was showed that ShaanxiProvince had good vegetation coverage that improved slightly as a whole during the past years.Annual average NDVI of the three regions were increasing each year

with increasing rates of the southern area>Guanzhong area>the northern area.By comparison

we found the vegetation NDVI had significant monthlyand less significant annual correlations with temperature and precipitation in different areas.The responsesvegetation NDVI showed no significant time lag to temperature and precipitation and exhibited noticeable lagto sunshine variations in Southern Shaanxi area.In Guanzhong and Northern Shaanxi area

in the response ofNDVI was found one month of time lag to temperature and sunshine lagged while no lag to precipitation.
