本文总结了1980-1981年对棉花、水稻受虫害后的光谱变化测试的初步实践,并对测得的数据经过概率统计分析。对可见、红外波段的遥感仪器作了探测虫害的理论分析,初步认为在0.75微米波段适用航空遥感技术,对获取的图象进行光密度的分析研究,可能实现棉花、水稻两大主要作物的虫害预测预报。
This paper summarizes the initial practice of measuring the spectral changes of cotton and rice after pests from 1980 to 1981, and the measured data are analyzed by probability and statistics. The remote sensing instruments in the visible and infrared bands made the theoretical analysis of detecting pests. It is preliminarily believed that applying the airborne remote sensing technology in the 0.75 micron band and analyzing the obtained optical density of the images can realize the pest of the two major crops of cotton and rice Forecast
