Abstract
Based on AVHRR data of NOAA satellite in 1988~1992,crop growth vigours in summer and autumn are analysed.Combinating those information with the practical grain yield and underlaying surface conditions,the threshold diferentiated by remote sensing NOAA/AVHRR is defined. The low-yield farmland in Huaibei Plain is classified.
