摘　　要：总结回顾了近30年来遥感信息获取技术、遥感找矿模型的发展历程和特点,提出了遥感综合信息找矿模型的基本概念及找矿预测方法。认为遥感综合信息找矿模型更加突出综合信息与找矿标志的系统组合,指出模型构建的关键是实现"地质找矿要素"向"遥感信息要素"的相互转换。以二连浩特北部地区为例,构建了该地区以遥感信息为主要数据源的遥感地质信息获取技术方法及找矿预测模型,圈定了5个重要的钨钼铜多金属矿找矿靶区,取得了较好的找矿应用效果。Remote sensing ore-prospecting model has developed with remote sensing data, remote sensing information acquisition technology and geological prospecting model. This study reviewed the development process and characteristics of remote sensing information acquisition technology and remote sensing prospecting model in the past 30 years, and proposed the basic concept and prospecting prediction method based on integrated remote sensing prospecting model. This model emphasized the combination of integrated information and ore-prospecting indicators, and the key of the model is the transformation of ＂geological prospecting elements＂ to ＂remote sensing information elements＂. Taking northern Erenhot as a case study, we proposed an acquisition method of remote sensing geological information and established an ore-prospecting model mainly based on remote sensing information. In addition, five important W-Mo-Cu polymetallic prospecting targets were delineated, resulting in an effective prospecting application.
