干旱区土壤含水量光谱特征分析与反演OA
Spectral Characteristics Analysis and Inversion of Soil Water Content in Arid Area
[目的]建立土壤含水量遥感监测模型。[方法]选取陕西省横山县作为研究区，以野外原位光谱测量数据和实验室内测得的土壤含水量为基础，进行高光谱数据处理，分析土壤含水量的光谱特征；对实测土壤光谱反射率进行倒数、对数、均方根及其一阶导数微分等光谱变化换，计算高光谱指数，并与土壤样本含水量进行相关性分析，筛选对土壤含水量敏感的光谱特征波段，利用多元线性回归分析建立土壤含水量监测模型。[结果]随着土壤含水量的增加，土壤光谱反射率呈减小趋势。土壤含水量与光谱指…查看全部>>
