| 摘 要： | 利用HR768型光谱仪,实地测定了古尔班通古特沙漠南缘60个样点的土壤光谱和土壤含水率。对测定的光谱数据选择土壤水分较敏感的红外波段与土壤含水率进行线性回归,结果表明：实测土壤光谱经对数变换后土壤光谱与其含水率拟合效果不理想,用去包络线且一阶微分方法对实测土壤光谱数据进行处理后,再与相应土壤含水率进行回归,其回归效果较好,决定系数R2达0.855该方法具有实用性强、易操作的特点,为沙漠区土壤含水率的反演提供新的方法和思路。

| Abstract: | The objective of this paper is to reveal the relationship between the soil moisture content and Hyperspectral.The paper tested 60 sandy soil samples in the south of Gurban tunggut desert with SVC field-portable spectroradiometer and established the liner regression between sandy moisture content and infrared bands which are sensitive to soil moisture content.The results showed that field test spectral of the sandy soil and logarithmic transformed refletance of the sandy soil did not show fine regression wit... |
