- Abstract:
-
Vegetation index has clear seasonality, which can describe the phenology variation information of vegetation. The variation and relativity analysis of different forest types NDVI and EVI has been achieved using MODIS/NDVI and MODIS/EVI time series data in HU’nan province. The results show that (1) For evergreen needle leaf forests, evergreen broad leaf forests, bamboo grove and shrub, NDVI has no clear seasonality with a flat curve; and EVI has a clear seasonality with a bell-shaped curve. (2) For deciduous broad leaf forests, NDVI and EVI have the same trends with a bell-shaped curve. EVI can describe the vegetation changes in different seasons preferably and can be used as the foundation data of identifying forest types appropriately.
