摘　　要：对西藏冲江地区进行以矿产勘查为主要目的的区域性地球化学调查工作,获得了系统而规范的面积性、多参数(十三种分析数据)的地球化学数据。通过分析所获取的地球化学图件,是化探数据最直接的表达方式。综合异常图作为地球化学的基础图件之一,它的编制主要涉及元素组合及主要元素的确定。以冲江地区综合异常图的编制为例,对编制过程中涉及的内容及其确定方法进行了详细的论述,为下一步异常筛选和异常查证工作提供了科学依据。Regional geochemical survey with the main purpose of mineral exploration was carried out in Chongjiang area of Tibet,and the geochemical data was gotten,which was integrity in Systematic and standardized,multi-parameter(13 types of data).The most direct expression way of geochemical data was analyzing geochemical map,and one of the foundation map of geochemical was integrated-anomaly map.The key compilation is to determination of element association and main elements.From example of compilation integrated-anomaly in Chongjiang Area,the authors discussed in detail on the problem of the compilation of Geochemical Integrated-anomaly Map,which provides a scientific basis in anomaly filtration and anomaly inspection.
