利用Quickbird多光谱影像和全色波段影像,借助ENVI遥感图像处理软件,从主观角度和定量的方法分析该影像3种融合方法的优缺点。结果表明：HSV和Brovey变化的视觉效果优于PCA变换;HSV与Brovey变换结果光谱保持能力类似,PCA融合的图像灰度级分布离散性优于HSV融合优于Brovey变换。

This research used multispeetral image and full color images of Quickbird to analyze the advantages and disadvantages of three fusion methods with the help of ENVI tools. The results suggested that HSV and Brovey showed better visual effect than PCA transform method. As for ability of keeping spectrum, HSV and Brovey were in the same quality better than PCA, and Brovey was superior in deflection. The dispersion deviation of image grey present this order ：PCA〉HSV〉Bruvey.
