| 中文摘要: |
| 福建上杭紫金山矿田地处武夷山成矿带南端，该区域高植被覆盖严重阻碍了与成矿有关的矿化蚀变信息的提取。针对植被的严重干扰和混合像元影响，应用混合像元分解技术去除植被干扰，消除植被端元影响，增强非植被信息，结合主成分法提取与矿化有关的蚀变信息。经与区域地质资料对比表明，混合像元分解结合主成分分析方法取得了很好的应用效果。 |
| 英文摘要: |
| Zijinshan Mountain ore field is located in the southern end of the Wuyi mountain metallogenic belt in Shanghang area, Fujian province. Alteration-mineralization information extraction from the area is severely hindered by the heavy vegetation and mixed pixel. Combined with principal component analysis technique and regional geological data the mixed pixel unmixing technique is applied to eliminate the vegetation interference and vegetation end member influence and enhance non-vegetation information and the extraction result is much better than that of the direct principal component analysis technique. |
