| 摘 要： | 土壤中黏土矿物高岭石的含量在地质找矿和环境治理方面有重要意义。对研究区土壤样品的短波红外反射特性进行了分析,通过连续统去除量化计算了光谱吸收特征参数,对比分析并检验高岭石含量与光谱吸收位置、深度、宽度和面积建立的线性方程以及与整个光谱区间(1 300 nm～2 500 nm)反射率建立的多元逐步线性回归方程,确定最优高岭石预测方程,其回归效果显著,预测精度较高。

| Abstract: | The kaolinite content of clay minerals in soil plays an important role in the fields of geological prospecting and geological treatment.The short wavelength infrared reflection(SWIR) characteristics of soil are analysised in the study area.Making use of the continuum removal method to calculate the spectrum characteristic absorption parameters.Comparative analysis and inspection the linear equation are built among the kaolinite content and the absorption positions,absorption depth,absorption width,absorptio... |
