利用NOAA/AVHRR多时相遥感数据，对内蒙古半干旱草原的初级生产力进行了估算。应用回归分析地面实况生物量和植被指数变量来自NDVI，PVI，MSAVI和GEMI。对AVHRR数据的植被指数变量类型、功能类型和大气效应进行了评价。结果表明，MSAVI的二次型函数可以有效地估算生长高峰期的区域初级生产力，且MSAVI对大气影响的敏感性较低。
By using NOAA/AVHRR multi-temporal data, the primary production was estimated in the semi-arid grassland of Inner Mongolia, China. Regression analysis was applied between ground truth biomass and vegetation index variables derived from NDVI, PVI, MSAVI and GEMI. The results were evaluated for vegetation index variable types, function types and atmospheric effects of AVHRR data. The results showed that the primary production of the region can be effectively estimated by using the quadratic-type function of MSAVI at the peak growth season, and MSAVI showed less sensitivity to the atmospheric effect.
