In this paper, 10-day (ten-day) spatio-temporal response of vegetation to the change of temperature and
precipitation was analyzed in spring, summer, autumn and whole year in Xinjiang, China during the
period of 1998-2009 based on the SPOT VEGETATION-NDVI data and 10-day average temperature
or precipitation data observed by 54 meteorological stations in Xinjiang through correlation analysis.
The results show that the response of 10-day NDVI to temperature was more significant than that to
precipitation, and the maximal response of vegetation to temperature and precipitation lagged for two
10-day periods. Seasonally, the effect of temperature and precipitation on vegetation NDVI was the
highest in autumn, then in spring, and it was the lowest in summer. The response of vegetation to
10-day change of meteorological factors was positive in spring, the affecting duration was long, and it
was relatively short in autumn and summer. Spatially, the 10-day maximal response of NDVI to
temperature in northern Xinjiang was higher than that in southern Xinjiang. The results indicated that
interannual change of temperature was not the dominant factor affecting the change of vegetation
NDVI in Xinjiang, but the decrease of annual precipitation was the main factor resulting in the
fluctuation of vegetation coverage. 10-day average temperature was an important factor to promote
vegetation growth in Xinjiang within a year, but the effect of precipitation on vegetation growth within
a year was not strong.
