摘要：

Variations of forest area and vegetation activity in China from 2001 to 2009 were investigated using the IGBP landcover data and the EVI (Enhanced Vegetation Index) dataset derived from Moderate-Resolution Imaging Spectroradiometer (MODIS) products in the 3 years of 2001, 2005, and 2009. The area of forests in China had increased by about 10%, and the changes in EVI-indicated vegetation activity showed large regional differences. The EVI decreased between 2001 and 2005 while it increased between 2005 and 2009 in most areas of southern China. It also indicated seasonal differences in different periods: an increase in fall between 2001 and 2005 and in spring between 2005 and 2009.
