摘　　要：文章旨在通过对遥感找矿地质方法的研究,总结出一套针对于藏东这种自然条件恶劣的特定地区的遥感找矿工作程序。通过运用比值分析+主成分分析提取矿化蚀变信息,运用方向滤波+掩膜的方法提取构造信息,从而确定了藏东东达山地区的遥感综合异常,并结合多源信息划分出了远景成矿区域,根据对东达山地区遥感找矿的方法研究,进而得到在东达山地区具有成矿潜力的区域范围,为藏东地区的进一步矿产资源开发与评价提供了依据。Based on study on ore -finding method of remote sensing, a working procedure of ore -finding by remote sensing in the Eastern Tibet which is under natural bad conditions is summarized. Meanwhile, author extracted alteration information by methods of principal component and ratio analysis, structural information by methods of directional filter and mask. Synthetical anomaly of remote sensing in the eastern Tibet is defined and perspective metallogenic province in the Dongdashan are of eastern Tibet is marked off. According to results of remote sensing＇ s methods, potential metallogenic area and further exploitation and evaluation of mineral resource in the eastern Tibet is proposed.
