摘　　要：泥沙来源判别是小流域土壤侵蚀研究的重点,也是难点。复合指纹识别技术因其结果直接、准确度高、作业快等特点,在国内外泥沙来源研究中得到大量应用,并迅速发展。复合指纹识别技术是在划分潜在侵蚀区的基础上,采集侵蚀区土壤样和流域出口泥沙样,室内分析土壤样和泥沙样指纹因子,利用相关统计检验方法筛选最佳指纹因子组合,利用数值转换模型将最佳指纹因子浓度转换为各侵蚀区产沙比例。主要通过阐述指纹识别技术泥沙来源研究步骤,总结现有可靠性检验方法,归纳研究对象等方面,综述基于复合指纹识别技术的泥沙来源研究进展。重点介绍了复合指纹识别技术最佳指纹因子组合筛选和数值转换模型,并指出复合指纹识别技术存在的问题。Composite fingerprinting,one of the most important method for sediment sources,is extensively used due to its accuracy,ubiquity and simpleness.Composite fingerprinting follows three steps for study on sediment sources.The first step is to classify and identify potential sediment sources within catchment and collect soil samples from the potential sediment sources and sediment samples from catchment outlet.The second step is to screen the optimal combination of fingerprints.The third step is to calculate the relative ration of each potential source.This paper introduces the development of composite fingerprinting by analysis of the steps of sediment sources using composite fingerprinting,reviews the methods of reliability test and summary of research object,and lays the emphasis on screening the optimal combination of fingerprints and the numerical mixing model.
