摘　　要：以黑龙江柴河地区为研究区域,探讨了运用ETM+遥感影像进行近自然彩色模拟的研究方法。首先分析了地物的光谱特性以及ETM+的波谱特征,说明各波段反映地物的适用性和局限性。然后,分析了遥感图像真彩色和假彩色合成的原理,揭示了近自然彩色模拟的实质,从理论上论证了近自然彩色模拟的可行性。近自然彩色模拟,所需解决的问题不仅涉及到视觉上的要求,更重要的是要考虑图像信息含量上的要求。这两方面必须有机结合,因此本研究具有一定的挑战性。Taking Caihe area of Heilongjiang province as research region, we discussed the method of simulating natural color on the base of ETM ＋ remote sensing image in this paper. In order to illuminate the applicability and limitation of each wave band, we analyzed both of the spectrum character of many object on the earth and the spectrum character of ETM ＋ image at first. This thesis demonstrated the key of simulating natural color and gave the theory of false color combination, and explained the essential of simulating natural color. We also demonstrated the feasibility of simulating natural color. This study resolved not only the matter of vision request but also the matter of quantity of information that remote sensing image contains. Satisfying both of the two aspects in reason challenges us in this paper.
