在柴北缘地区利用ETM数据进行遥感矿化蚀交信息提取方法研究主要基于三个方面:①研究区蚀变信息及背景干扰地物信息的光谱特征;②矿化蚀变信息提取的最佳变量集组合;③图像增强处理方法和流程.在综合分析研究的基础上,采用"图像掩膜→最佳变量组合→波段比值→主成分分析→阈值分割→多元数据综合分析及异常筛选"的方法和流程提取了柴北缘成矿带的矿化蚀变异常信息,为该区综合成矿预测提供了可靠依据.

In the northern marginal of Chaidamu Basin,the research on extraction method of the mineralization alternation information with ETM image is based on three aspects: ① the spectrum features of background interference information & alteration of information in the study area;② the best combination of variables of mineralization alteration information extraction;③ image enhancement processing methods. Based on comprehensive analysis, the method of "mask image→the best combination of variables→band ratio→principal component analysis→multi-data analysis & abnormal screening" is used to extract mineralization alteration abnormal information in the study area. The research provides a reliable basis to the area of comprehensive forecasting.
