摘　　要：遥感线性体研究是地质科学技术与卫星传感器技术的有机结合,由于其多半是受构造控制的线性要素,因而被认定为断裂常规研究方法的有益补充和探索隐伏构造的必然趋势.以会泽铅锌矿为例,在经过假彩色合成和滤波处理的美国Lansat-7卫星ETM+遥感图像上,通过详细区分构造的典型判别标志.对研究区线性构造进行目视解译,并对解译结果进行相应的统计分析,作出相应的线性体等密度图、方位雷达图,方位-强度图及线性体方位非异常度图,进而从不同角度系统地论述了该区域断裂构造的特征和展布规律,揭示了NE、NW向控矿构造即为优势方位构造的结论,并为该区域构造演化及成矿规律的定量研究提供了相关的指标和依据.Remote sensing research of linear structure is the combination of geological science and technology and the satellite sensor technology, as it is mostly the tectonic elements controlled by structure, including any cause different fuzzy line or linear array, as a result they have been identified as a good complement to conventional research methods and the concealed structure development inevitable trend. Taking Huize lead-zinc mine as the research area, in the Lansat-7 ETM＋ satellite remote sensing images of the United States with false color composite and filter processing, through detailed distinguish tectonic discriminant mark, visual interpretation of the linear structure in the study area is done. And by corresponding statistical analysis of the interpretation results,we maked corresponding linear density figure, such as location radar map, bearing-strength figure and linear bearing the abnormal body figure, and then systematically discussed the characteristics and distribution law of fracture structure in the area from different angles. It was revealed that the NE and NW to the conclusion of ore-controlling structure is the superiority trend. The study provides the related indicators and basis for the quantitative study of the tectonic evolution and metallogenic regularities.
