| 中文摘要: |
| 遥感技术的飞速发展为应用部门提供了大量地球资源信息,遥感数字图象处理技术已日趋成熟.对遥感数据进行特殊的增强处理从而提取矿产信息是遥感地质专业领域重要的发展方向.美国地质调查所已把利用陆地卫星多光谱扫描数据在干旱、半干旱地区进行褐铁矿露头圈定作为一种常规的地质手段.有人成功地在植被茂盛区进行了褐铁矿露头的圈定.北京大学刘燕君老师和首钢陈希华合作在密云一迁安铁矿区进行了铁矿信息的提取,取得了较好的效果.白云鄂博铁矿是世界上最大的含铌稀土铁矿之一,地处干旱地区,植被覆盖稀少.矿体出露良好.笔者选择该区进行图象增强处理提取铁矿信息的方法探讨,已知的东矿、主矿、西矿都得到了彩色异常显示. |

| The digital enhancement processing of remote sensing image using Landsat multispectral scanner data was carried out aiming at enhancing iron ores informarion.Better results have been achieved by means of ratio-colour compound 5/4-4(red),5/6-6(green),5(blue)and ratio combination KL transfer,for all the known iron ores have got the display of abnormal coiour.The same abnormai colour was also found in the northern part of Kuangou fault.It is already proved that the abnormal colour district belongs to the same ore - bearing horizon with Baiyunebo iron ore zone,thus it should be further examined. |
