摘　　要：基于Hyperion高光谱遥感数据,采用像素纯度指数(PPI)和光谱角制图(SAM)等光谱分析方法对河北宣化盆地第四纪地层的分布情况进行定量提取,并对获取的结果进行实地验证和优化.同时,分析了第四纪地层的分布与宣化盆地南缘断裂带活动之间的关系.Hyperspectral remote sensing technique has been developed rapidly since 80 sof the 20 th century,because it has the advantages of high spectral resolution and the ability to present imagery and spectral profile together.In this paper,the Quaternary strata at the Xuanhua Basin in the Hebei Province was extracted from the Hyperion data using spectral analysis methods such as Pixel Purity Index（PPI）,Spectral Angel Mapper（SAM）and so on.The extracted results were verified with field work.Based on the improved results,the relationship between Quaternary strata and activities of the Southern Margin Fault at the Xuanhua Basin was discussed.
