| 摘 要： | 分别对草甸、草原和荒漠3种草地类型进行了生物量的实测工作。根据同步的MODIS与AVHRR资料，应用ENVI软件提取出这两种传感器在3种草地类型上的植被指数：NDVI和RVI。经过统计分析得到两种传感器在3种草地类型上的生物量模型，从而建立起MODIS植被指数与草地生物量的相关关系，并对MODIS和AVHRR植被指数估产模型进行了评价与分析。

| Abstract: | During this studying,three grassland types,the meadow,the prairie and the desert,were chosen to do the biomass measurement.According to the synchronized data of MODIS and AVHRR and using ENVI software,we extracted the vegetation indexes,NDVI and RVI,obtained from two sensors,of three grassland types respectively,and formed two biomass models of three grassland types by statistical analysis,thereby set up the linear relation between MODIS vegetation index and the real measured grassland biomass,and estimated and analyzed the yield estimating model of the vegetation index of MODIS and AVHRR. |
