摘要

根据鄱阳湖南矶山区域土壤的X荧光光谱和可见近红外光谱特征，建立了3种数据融合(等权融合、累加融合、外积融合)的最小二乘向量机定量分析模型。结果表明，等权融合和外积融合模型精度和稳定性均优于单一光谱定量分析模型。其中外积融合模型性能最佳，其决定系数(R2)为0.85，校正均方根误差(RMSEC)为009，预测均方根误差(RMSEP)为006，相对分析误差(RPD)为2.41，满足实际土壤中Cd的检测需求。该方法准确可靠，可为我国土壤重金属分类分级方法研究提供参考。

Abstract

According to the characteristics of X-ray fluorescence spectrum and visible near infrared spectrum for soil in Nanji area of Poyang Lake

three quantitative analysis models for data fusion

including equal right fusion

co-addition fusion and outer product fusion based on least squares vector machine(LS-SVM) were established.Results showed that the models for equal right fusion and outer product fusion have better accuracy and stability than the single spectral quantitative analysis model has

in which the model for outer product fusion exhibits the best performance with a determination coefficient(R2) of 0.85

a root mean squared error(RMSEC) of 0.09

a root mean square error of prediction(RMSEP) of 0.06 and a relative percent deviation(RPD) of 2.41

satisfying the detection requirements.With the advantages of accuracy and reliability

the developed method could provide a reference for the study of soil heavy metal classification and grading method in China.
