摘要
植被指数的时空变化是目前全球变化研究的热点问题。该文以江苏沿海互花米草盐沼为例,运用MODIS数据探索沿海带状植被NDVI/EVI的季节变化规律。结果表明,互花米草的返青(出苗)、抽穗、种子成熟等主要物候期在VI曲线上均能得到很好体现。本研究可为监测互花米草盐沼扩展趋势、加强管理、趋利避害提供基础数据,同时也为沿海其它带状植被监测提供借鉴。
The space-temporal change of vegetation index is the core project of global change. Based on field measured data and MODIS-NDVI/EVI, the paper explored the seasonal dynamics of NDVI and EVI ofSpartina alterniflora on the Jiangsu coast. The result showed that different phonological stages during the Spartina alterniflora growth period including recovering, heading and seeds mature can be found from the curves of NDVI and EVI during the year. The research of this article not only can offer effective basis for monitoring spread trend, strengthening management, increasing advantages and reducing disadvantages of Spartina alterniflora salt marsh, but also can be use for reference by other zonal vegetation in the coastal area.
