摘　　要：利用C-A(含量-频数)多重分形技术和传统的异常下限统计方法分别对东天山地区钼地球化学数值的异常进行了试验分析。结果表明:利用C-A多重分形的非线性统计方法计算更为方便,确定的异常下限值更为合理;采用非线性统计方法确定的异常下限与东天山地区已知矿点的吻合度较高,说明利用分形方法可以客观反映区域地球化学异常特征;C-A多重分形方法计算方便,可为资源预测提供定量基础。The authors conducted a test analysis on Mo geochemistry numerical value anomaly in eastern Tianshan Mountains with CA（ Content-Absolute frequency） multi fractal technology and the traditional anomaly threshold statistics. The results showed that the determination of anomaly threshold was easy with nonlinear statistics of C-A multi fractal technology and the values were rational and matched the other known ore occurrences. It was concluded that C-A multi fractal method could reflect the regional geochemical anomaly characteristics more objectively,provide quantitative basis for minerals prediction.
