【摘要】 针对高寒山区矿产资源丰富,但自然环境条件恶劣,采用传统的地质找矿方法难度较大的特点,以青海省乌兰—都兰地区(简称两兰地区)为研究对象,针对多元找矿信息的空间相关关系,采用遥感化探信息融合处理技术,提出基于套合关系的彩色图像合成、基于耦合关系的HIS彩色空间变化、二维相关编码和关联系数变换等综合技术模型,优选出具有地质找矿意义的综合异常和有利矿化地段。研究结果表明:采用这种方法能实现遥感与化探信息的综合处理,优选出找矿异常和找矿目标,为加快矿产资源勘查评价以及找矿技术方法优选提供科学依据。更多还原

【Abstract】 Based on the fact that the high and cold mountainous area has rich mineral resources and great prospecting potential,but it is hard to prospect ore,taking the Lianglan areas in Qinghai study area was taken as studied object,a strong basis to speed up the evaluation of mineral resources in this area was studied using the modern computer information processing technology for the integrated processing of remote sensing and geochemical information and the deep level metallogenic information extraction. The results show that the comprehensive analysis model is based on the relationship between the sets and coupling and the corresponding techniques,the comprehensive processing of remote sensing and geochemical information can be obtained,and the integrated exploration anomaly and prospecting target can be optimally selected. It is helpful to speed up the evaluation of mineral resources and optimize the prospecting methods.更多还原
