In view of the situation that research on vegetation cover change and climate change is less this paper took Sichuan Basin as an example and analyzed the correlation between vegetation coverage degree and temperature according to Pearson correlation coefficient using MODIS hyperspectral data and vegetation covering degree as an index of monitoring the dynamic changes of vegetation.Finally,this paper summarized the trends of vegetation cover changes in Sichuan Basin from 2003to 2010,and studied the effect of temperature variation to vegetation coverage.Studies showed that the relation between vegetation cover degree and temperature was strong positive correlation,and their variation trends were similar excepting some special circumstances like earthquake,the trend was high in summer while low in winter.
