英文摘要：

Spatial resolution of remote sensing fused image is usually the spatial resolution of high spatial resolution image which is not the real spatial resolution of the fused image. A method using correlation coefficient and bias index of different spatial resolution image base and fused image to quantitatively determine spatial resolution of remote sensing fused image is presented. The experiments show this method is not only plain and practical but also easy to realize.
