The study of correlation analysis between the saline soil hyperspectral reflectance and the surface soil conductivity at the Weigan-Kuqa rivers delta oasis

Abstract

This study selected the Weigan- Kuqa river delta oasis in Xinjiang, where located a large areas of saline soil as the study area, using EM38 conductivity meter and ASD Field Spec Pro FR spectrometer, studied the correlation relationship between the arid zone saline soil hyper spectral and surface soil conductivity. The soil conductivity estimating model under the 3 different spectral index is established. And the scientific basis for saline soil remote sensing monitoring in a further way was provided.
