| 摘 要： | 应用HIS变换、主成分变换和Brovey变换等3种影像融合方法对QuickBird多光谱和全色遥感影像进行融合，并利用标准偏差、相关系数和偏差指数等指标对融合效果进行定量评价；利用基于融合后的高分辨率影像对魏沟流域大比例尺土地利用的遥感调查进行了试验和研究。结果表明：主成分变换法的融合效果最佳；梯田、坡耕地和灌木林地分别占流域土地总面积的34．22％、16．42％和10．67％，是主要土地利用类型．

| Abstract: | As a case study of merging QuickBird multispectral and panchromatic remote sensing image,HIS,PCA and Brovey are chosen and their merging effects are evaluated quantificationally by standard deviation,correlation coefficient and difference index.Based on merged image,experimental research to investigate the land use with large scale in Weigou Watershed in 2004 is conducted.It is indicated that merging effect of PCA is beyond other 3 algorithms;as 3 main land use types,terrace,sloping cultivated land and shrub land account for 34.22%,16.42 % and 10.67% of the total land area respectively. |
