Enhanced vegetation index using Moderate Resolution Imaging Spectroradiometers

The enhanced vegetation index (EVI) was developed as a standard satellite vegetation product for the Terra and Aqua Moderate Resolution Imaging Spectroradiometers (MODIS). In this paper, MOD3A3, a global dataset with 1km spatial resolution and one month temporal resolution, was selected as the data source. The dynamic changes of vegetation EVI in China region and the seven regions of China during the period from 2001 to 2011 were studied by using maximum value method, average method and linear regression trend analysis method. Results show that: Over the past 11 years, the change of China Annual EVI was insignificant. The variation of mean EVI of different regions was obvious. Trend analysis shows that vegetation EVI in China had an increasing trend from 2001 to 2011.
