摘要
建设用地动态监测是各地国土资源大调查中的重要内容，而遥感影像处理中的融合过程又为其提供了优化数据源．在融合过程中，选择常用的融合方法对研究区SPOT5影像进行实验研究，并采用主观定性和客观定量方式评价其融合结果．研究表明：IHS变换法、高通滤波法和小波变换法相结合的融合图像效果最好，其空间特征明显且光谱信息损失较少，更适合于SPOT5影像中新增建设用地的提取．
Image fusion of remote sensing image processing provides the optimal data for construction sites dynamic monitoring , which is an important part of many, regions＇ land resources surveys. In the process of fusion, six kinds of fusion methods were used in SPOT5 image fusion research, and then the fusion results were evaluated by the way of subjective qualitative and objective quantitative analysis. The results show that the image fused by IHS ＋ HPF ＋ WT method has much better effect ： distinguished spatial characteristics as well as losing less spectral information. This method is more suitable for new Construction sites extracted of SPOT5 image.
