摘要
In this paper, relevant literatures in the field of rocky desertification research are summarized, and methods of extracting rocky desertification information from remote sensing data are taken as the main line to analyze and discuss the evaluation index of rocky desertification and remote sensing information extraction of rocky desertification. This paper also summarizes the progress and shortcomings of human-computer interactive interpretation, supervised classification, unsupervised classification, object-oriented classification, and remote sensing data extraction of rocky desertification information, including multi-spectral remote sensing, hyperspectral remote sensing, microwave remote sensing and unmanned aerial vehicle remote sensing. The future development trend of remote sensing image information extraction methods in rocky desertification areas in my country is prospected. It is pointed out that more attention should be paid to the quantification of the classification index of rocky desertification degree, and the further research on the fusion of multi-source data features should be conducted to improve the accuracy of rocky desertification information extraction.
