In view of the problems of one-sided appraisal when using single character parameter to evaluate geomagnetic map suitability, multi-attribute decision making method based on maximum deviation and maximum entropy is applied to the overall evaluation of suitability. Geomagnetic map character parameters such as standard deviation, roughness, correlation coefficient and entropy are considered to achieve the synthetical evaluating indicator by setting the weight coefficient. By simulation using correlation matching algorithm, the results indicate the favourable consistency between synthetical evaluating indicator and matching probability. The bigger synthetical evaluating indicator is, the higher matching probability is. It is reasonable to treat synthetical evaluating indicator as quantitative basis of suitability.%针对单一特征参数评价地磁图适配性不全面的问题,采用基于最大离差和最大熵的多属性决策方法对地 磁图适配性进行综合评价.综合考虑地磁标准差、地磁粗糙度、地磁相关系数、地磁信息熵4个地磁图特征参数,通过确定各参数的权重,求解出地磁图的综合评价值,并利用相关匹配算法进行仿真实验.结果表明:地磁图的综 合评价值与匹配概率有良好的一致性,综合评价值越大,匹配概率越高,可将综合评价值作为地磁图适配性分析的 定量依据.
