用遥感技术进行植物评估可与光谱植被指数联系起来，如规一化差分植被指数NDVI。
Plant condition assessment using remote sensing techniques have been associated with spectral vegetation indices such as the normalized difference vegetation index (NDVI).
在此基础上分析了不同氮素水平冬小麦生育期内的光谱植被指数的变化，并分析了农学参数与植被指数之间的相关性。
Furthermore, the variation of spectral vegetation index of winter wheat under different nitrogen levels and the correlation between agronomic parameters and spectral variables were analyzed.
该地图是根据NASA泰拉(Terra)卫星的中分辨率成像光谱仪(MODIS)的植被指数数据制作的。
