引言作者从1985年起在黑龙江省北安地区开展了春小麦遥感估产研究,建立了光谱产量模式及气象产量模式,4年来予报单产准确率在90％以上;同时应用TM影像对春小麦种植面积进行了测算,也取得了满意的结果。证明利用遥感技术对春小麦进行估产要比常规调查方法及时、准确、省工而又经济。应用遥感技术对农作物长势进行监测和产量予报,是以农作物对太阳辐射的反射、吸收特征为基础, Introduction Since 1985, the authors conducted spring wheat yield estimation study in Bei’an, Heilongjiang Province. The model of spectral yield and meteorological yield have been established. The accuracy rate of yield per unit area is more than 90% in 4 years. At the same time, The calculation, but also achieved satisfactory results. It is proved that using remote sensing technology to estimate spring wheat is more economical, time-consuming and accurate than routine investigation. Application of remote sensing technology to monitor the crop growth and yield to be reported based on the reflection of crops on solar radiation, absorption characteristics,
