摘要
[目的]利用高光谱遥感,对武夷山土壤有机质进行研究,建立了土壤有机质高光谱反演模型,为今后武夷山地区土壤有机质含量的快速测定提供理论依据。[方法]利用ASD Field Spec Pro地物光谱仪对不同有机质土壤进行光谱测量,采用有机质速测法对土壤有机质含量进行测定。[结果]762 nm为土壤有机质的敏感波段,其相关系数为-0.771,然后建立拟合方程为:Y=61.823-129.274x,拟合度为0.820。[结论]提出今后亚热带地区土壤高光谱的研究方向。
[Objective]The hyperspectral model of soil organic matter content was established by utilizing hyperspectral remote sensing.It could provide the theory basis for rapidly measuring soil organic matter content in Wuyishan area.[Method]The spectra of soil samples were measured by ASD Field Spec Pro and the soil organic matter content was measured by the method of organic matter rapid testing.[Result] Based on the correlation analysis,762 nm was the most sensitive band for soil organic matter content.Moreover the equation Y=61.823-129.274x was established and the fitting degree was-0.771.[Conclusion] The further research＇s direction of soil hyperspectral study in substropical area was come up with.
