| 摘 要： | 根据冬小麦和土壤地面反射波谱测试数据，计算了在卫星高度上与卫星磁带数据相对应波段的辐亮度值，对ＮＯＡＡＡＶＨＲＲ和ＴＭ某些通道的差值绿度植被指数ＤＶＩ、归一化绿度植被指数ＮＤＶＩ和比值绿度植被指数ＲＶＩ的分析，从理论上证明了目前采用ＴＭＤＶＩ＿（４，３）提取冬小麦种植面积和ＮＯＡＡＮＤＶＩ＿（２，１）区分植被和土壤背景的有效性。同时在冬小麦种植面积和长势监测方面提出了一些新建议。

| Abstract: | According to the spectral data of winter wheat and background soil which reflect solar spectrum,the spectral radiances at the satellite altitude were estimated,and then the radiances of the correspon-dence with the wave bands of satellite probe were done. Then some vegetation indexes(for example DVI,NDVI,RVI)had been analysised,and it gives proof of the efficiency for obtaining the planting arca of winter wheat through the method of TM DVI[4,3],and differentiation of vegetation and background soil is done through the popular method of NOAA AVHRR NDVI[2,1].Some new sug-gestion for the planting area of winter wheat and the monitor of its growing situation have been put forward in the paper. |
