| 摘 要： | 基于NOAA-16/AVHRR的资料结合定西和兰州的地面反射率观测资料,推算中国西北区东部地表特征参数和植被指数的最佳方案,用2001~2003年4~8月作物生长季5个地表特征的图像,按不同的土地覆盖类型分析地面反射率、表面温度、地气温差、植被指数（NDVI）、修正的土壤调整植被指数（MSAVI）和植被覆盖度的区域分布特征。结果表明,NDVI和MSAVI两者在不同的土地类型之间变化差别明显,尤其是在黄土高原与秦岭山地和青藏高原交界处的变化差别更明显。

| Abstract: | Based on the NOAA-16 AVHRR data and combined with the surface reflectivity observation data in Dingxi and Lanzhou,the best scheme of land surface parameters and vegetation indexes in eastern part of Northwest China were calculated.By the use of five scences of land surface parameters of the growing seasons from April to August in 2001-2003,the regional distribution characteristics of surface reflectivity,surface temperature,difference between surface and air temperature,NDVI,MSAVI and vegetation coverage ra... |
