| 摘 要： | 以ETM＋图像数据为信息源，运用比值变换和主成分分析技术，进行数据融合和图像增强处理，结合数字高程模型，提取新疆哈拉奇地区构造和近矿围岩蚀变信息。根据线性构造的影像特征分析，划分出3个构造组合：区域性近东西向、北东向、北西向构造。同时利用分形理论的求和法进行了研究区遥感蚀变异常的提取，并将蚀变结果与构造和化探异常区进行了对比分析。

| Abstract: | The information of tectonic structure and surrounding rock alteration is extracted from ETM remote sensing data through data amalgamation and image enhancement by ratio transformation, main component analysis and digital elevation model （DEM）. According to the image characteristics of linear structures, three structural trends are identified, nearly EW, NE and NW direction. The paper uses fractal theory for remote sensing alteration anomaly extraction, and contrast the result with fault and geochemical abnormal area. |
