Abstract

The temporal and spatial variation of vegetation index is a hot issue in global change research currently.Spartina alterniflora salt marsh in Jiangsu coastal areas is taken as an example in this study, MODIS data is used to research NDVI/EVI seasonal variation laws of coastal zonal vegetation. The results show that the major phenological periods of S. alterniflora, such as turning green (seedling emergence), heading and seed maturity, could be well reflected with VI curves. This study provides basic data for monitoring expansion trend of S. alterniflora salt marsh, strengthening management, drawing on advantages and avoiding disadvantages, as well as supplying references for monitoring of other zonal vegetation in coastal areas.

 

Key words: Spartina alterniflora, seasonal dynamics, zonal vegetation.
