Method and system for monitoring soil degradation of dry-hot valley plain land

Abstract

This invention provides a method and system for monitoring soil degradation in plains of arid-hot river valleys, belonging to the field of soil degradation monitoring technology. The method involves dividing the area to be monitored into grids to obtain multiple monitoring sub-regions, and monitoring each sub-region separately. The steps include: periodically collecting multiple soil attribute data from the monitoring sub-regions to form a multi-soil attribute data vector at a unified time scale; identifying multiple soil degradation problems and establishing a mapping relationship matrix and coupling coefficients between the soil degradation problems; constructing a barrier degree model for each soil degradation problem; outputting initial risk assessment parameters for various soil degradation problems in the monitoring sub-regions of the current collection period through a risk evolution model; and performing soil degradation trend analysis based on the initial risk assessment parameters. The advantages of this invention are improved foresight, accuracy, and interpretability of soil degradation monitoring.
