| 摘 要： | 利用1991～2000年NOAA气象卫星遥感资料和同期山东冬小麦产量资料，分区建立了冬小麦产量与植被指数之间的关系式，推算出每个像元点的产量，按照划分高中低产田的阈值，将该像元点确定为某一产量类型，在GIS的支持下，形成了山东省冬小麦高、中、低产田分布图，同时，对于中低产田的成因进行了初步分析。

| Abstract: | Based on the remote sensing data of NOAA/AVHRR from 1991 to 2000 and the winter wheat yield data at the same period, the correlation equation between winter wheat yields and vegetable index of every pixel was established and hereby the winter wheat yield of every pixel was computed. According to the threshold values of the high, middle and low yield farmlands, the yield type of every pixel was determined. The distribution diagram of winter wheat yield types in Shandong was given by means of GIS. The formation causes of the middle and low farmlands were analyzed. |
