摘　　要：利用我国自主研制的环境一号小卫星A星上搭载的CCD相机与高光谱成像仪(HSI),以洪河国家级湿地为研究区,进行融合实验。先分析了两种载荷的特点,然后根据载荷特点,设计并评价了两种载荷数据融合的方法。结果表明,由于A星CCD相机与高光谱成像仪成像条件相似,可以对两个载荷的数据进行融合,得到具备较高分辨率与光谱分辨率的数据,为后续高精度分类制图、目标识别、信息提取等应用提供高质量数据源。The paper tried to fuse Hyper Spectral Imager（HSI）and CCD data of HJ-1A Satellite which was developed by China independently.At first,we chose Honghe wetland as study area,and analyzed the data features of the two sensors;then we designed a fusion method based on these features and evaluated the fusion result.Finally,The paper reached the conclusions：（1）Due to the similarity of the imaging condition,the CCD and HSI data can be registered with each other well and then can be fused to acquire the data with higher spatial and spectral resolution.（2）The fused data can be applied to high-precision classification,target-identification and features extraction.
