摘　　要：通过对定点监测资料和NOAA/AVHRR资料的平行分析,探讨了NOAA/AVHRR资料在小区域冬小麦长势动态监测中的应用问题,建立了农学参数与遥感绿度值之间的关系式和卫星遥感苗情分类指标动态方程,为当地冬小麦卫星遥感苗情分类提供了一套客观实用的方法。The monitoring data in a small area is analyzed with NOAA/AVHRR data in a parallel way. NOAA/AVHRR data gets applied to winter wheat growth monitoring of the small area. The relationship between the agricultural index and the degree of greenness by remote sensing is set up with the developing equation in the satellite remote figures of crop classification. So a set of practical methods of classifying crops by means of satellite remote sensing are provided for the local area.
