摘　　要：针对遗址文物磁源体异常信息通常在性态和类属方面存在一定的中介性,通过实验测试,研究了成都金沙遗址发掘象牙、陶器、动物遗骸等文物遗存样品的地球物理特征,综合分析了全区高精度磁测异常分布特点,并采用基于传递包的模糊聚类分析方法,克服了传统硬划分聚类处理的局限性,由此建立了研究区磁源参数量化特征的模糊相似关系。对研究区异常进行了聚类划分和识别,指出了遗址区三类文物赋存特点和分布状况,为指导该区文物发掘和保护起到了重要作用。There often exists a certain intermediary propert and classification of the anomalous information of the magn properties of those cultural relics samples, such as unearth studied by corresponding measurement at lab. The dist magnetic anomaly of the study area are also analyzed discrimination methods based on transmittal bags, y when people consider the characteristics etic source. In this paper, the geophysical ed ivories, china and animal remains, are ribution properties of the high-accuracy and by using the fuzzy clustering and classification method in clustering analysis are overcome. resemble relationship of the quantitative nature of the magne established. Fuzzy clustering conditions and accumulation p out. This takes an important limitation Based on tic source and discrimination are conducted in s of the traditional “stiff” the above studies, the fuzzy parameters in the study area is the study area, and the distribution roperties of those three kind culture relics in the study area are pointed role in guiding the relics protection in this area.
