摘要(Abstract)：

针对复杂艰险地区修建道路时,地质岩性难以现场获取的问题,该文利用ASTER多光谱遥感影像,研究和设计了一种顾及植被覆盖的复杂艰险地区多光谱遥感岩性信息识别提取方法。该方法根据植被覆盖情况先分类后进行岩性识别:对中高植被覆盖区进行植被信息的抑制处理,再对中低植被覆盖区采用主成分分析法进行岩性信息提取;对低植被地表裸露区域采用端元提取、光谱角填图的方法进行岩性信息的提取。最后将岩性识别提取结果与现场地勘结果进行对比验证。结果表明该方法进行岩性信息提取结果与已有的现场勘察结果基本一致,具有重要的参考和应用价值。

关键词(KeyWords)： 多光谱影像;岩性识别;植被覆盖;光谱角填图
