摘　　要：论证了热红外遥感技术探测种植玉米良种适宜积温地块的物理依据 ,探讨了实现这一目的的技术途径与方法。以监督彩色密度分割后的热红外辐射温度等级分布图为基础 ,建立了辐射温度与相应积温的对应关系 ,并结合多伦县的实际情况利用遥感方法对该区玉米良种适宜地块的分布进行了分析 ,为多伦县寻找种植玉米良种适宜积温地块提供了科学的依据。2 0 0 0年多伦县推广种植情况表明该技术方法具有良好的应用效果。The principle and technical approaches of using thermal infrared remote sensing techniques to detect suitable accumulated temperature area of planting improved variety of marize in Duolun were discussed in this paper. On the basis of radiant temperaturel grade image of thermal infrared of supervised color density slicing, the authors established a corresponded relationship for the radiant temperatures and relevant accumulated temperatures. Distribution for suitable accumulated temperature area in Duolun was analysed using remote sensing method and combining with the practical situation of the region.This paper provided scientific basis for searching suitable accumulated temperatures area of planting improved variety of marize in Duolun. It was proved that the method of remote sensing technique has good effects on spreading plantation of improved variety of marize in 2000 year.
