    Abstract:
    Vegetation index (VI) is an important criterion to evaluate vegetation condition. VI time series can be used to judge the spatialtemporal change rul e s of the vegetation coverage, land use and soil moisture, also they can be used to monitor drought and vegetation condition. Three kinds of vegetation indices, i.e ., ratio vegetation index (RVI), normalized difference vegetation index (NDVI) a nd enhanced vegetation index (EVI), were selected to establish the time series f or Guangdong province using maximum value composites (MVC) based on MODIS data i n 2004-2006. The rules of vegetation growth were analyzed in different vegetatio n cover type for the three vegetation indices. The vegetation coverage was compu ted by NDVI and classified to ana
