| 摘 要： | 通过对哈尔滨市土壤样品实测和室内高光谱测定,以土壤光谱反射率(反射率倒数、反射率对数、反射率一阶微分等)的数学变换数据作为自变量,土壤有机质质量分数的对数作为因变量,利用Matlab7.1软件,多元统计分析方法,建立了哈尔滨市土壤有机质质量分数高光谱多元逐步回归分析模型,实现了对哈尔滨地区土壤有机质的快速预测。

| Abstract: | An experiment was conducted to study the rapid method for the determination of soil organic matter in Harbin City based on the results of soil sampling and indoor spectrometry measurement. A multiple stepwise regression model was established by Matlab7.1 and multivariable regression analysis using spectral reflectance (Reciprocal reflectance,Logarithm of reflectance,first derivative of reflectance) as the independent variables and logarithmic value of soil organic matter content as the dependent variable. |
