摘　　要：本文介绍了建立进口铁矿产地鉴别数据库的方法。首先利用X射线荧光光谱法测定所收集的进口铁矿样品中的主要元素含量,在大量检测数据的基础上,采用数理统计的方法即逐步判别法对不同元素和产地国别的关联程度进行计算,筛选出关键的指标组合;然后采用非参数判别方法,建立进口铁矿产地鉴别模型,并利用历史数据集评估该模型的可靠性。应用本鉴别模型能够准确的判断出产地为巴西、伊朗的铁矿,对于澳大利亚和印度的铁矿可能会出现误判,但随着实验数据的不断积累,鉴别模型还会继续完善。该模型的建立将直接应用于进口铁矿的产地鉴别,对于保护我国进口铁矿贸易相关方的经济利益、保障矿石质量安全、维护国家外贸秩序都将起到积极的作用。This paper introduces the method of establishment of origin identification database of import iron ores.At first,we determined the main elements in the collected import iron ore samples by X-ray fluorescence spectrometry.Based on a large amount of test data,used the mathematical statistics method,that is stepwise discriminant analysis method to calculate the correlation degrees on the country origins and elements.After selected the key test items combination,used the discriminant method of non parameter to establish the origin identification model of import iron ores.Finally,we assessed the reliability of the model by historical data.This model can accurately identified origin of Brazil and Iran iron ores,and identified India and Australia iron ores may be mistake.With the accumulation of experimental data,the identification model will continue to improve.Identification of the model will be directly applied to imports of iron ores,protected our import of iron ores trade economic interested parties,and play a positive role to safeguard the ore quality security and safeguarding national foreign trade order.
