THEOS是一种新的高分辨率卫星数据,探讨THEOS数据的融合方法对于促进它的应用具有重要的实践意义,依据THEOS数据的特点,应用几种常见的融合方法,进行融合试验,从主观和客观两方面分别进行了定性和定量评价,实验发现IHS变换法在保持多光谱信息,提高清晰度方面优于其它几种融合方法。

英文摘要：

As a new kind of high-resolution satellite data,the research on THEOS data fusion will be very significant in promoting its application.According to the characteristics of THEOS data,several common fusion methods were used to evaluate the quality of fusion images with both subjective and objective methods.The result shows that the IHS method gets the advantage over the other fusion methods in the aspect of visual results and identifying precision.
