Relationships between soil salinization and spectra in the delta oasis of Weigan and Kuqa Rivers.

Data from remote sensing,ground-based electromagnetic induction and ground soil salinity were used to analyze soil salinization in the delta oasis of Weigan and Kuqa Rivers,and to calculate the Pearson correlation coefficient between 14 soil salt factors and bands of 405 nm,410 nm,…,890 nm.The results generally showed little correlation.Based on the above data,a model for predicting soil salts was established using multivariate linear regression analysis,and a precision model for predicting pH was also validated.In addition,the distribution extent and the degree of soil salinization were shown based on field surveying,GPS and soil sample analysis.
