摘　　要：以浙江省湖州市东林镇的SPOT5遥感影像为基础数据,利用几种融合后的影像进行土地利用变更调查,根据其精度对比结果,建议针对不同地物,采用不同方法融合的影像进行变更调查,以提高利用遥感影像进行土地利用变更调查的精度.同时,对利用SPOT5遥感影像进行土地利用变更调查,并输出1∶1万成果图的可行性进行了讨论.This paper discussed the image fusion methods of SPOT5 multi-spectral bands and SPOT5 panchromatic band for improving land use change survey accuracy. HIS (Hue, Intensity, Saturation) transform and Principal Components Analyse transform were applied to the test data, then visual interpretation and man-computer interactive interpretation methods were used to classify the fusion image. The accuracy of different fusion methods was compared. The results indicated that it was better to apply different fusion methods to SPOT5 image integratedly to carry on land use change survey and output result map at 1∶10000 scale.
