Study on the Pretreatment of Soil Hyperspectral and Na<sup>+</sup> Ion Data under Different Degrees of Human Activity Stress by Fractional-Order Derivatives
Soluble salts in saline soil often exist in the form of salt base ions, and excessive water-soluble base ions can harm plant growth. As one of the water-soluble base ions, Na+ ion, is the main indicator of the degree of soil salinization. The pretreatment of visible, near infrared and short-wave inf...
