Abstract

The application discloses a land system status evaluation method, device and storage medium. Among them, the evaluation method of land system status is used to evaluate the status of land system in a predetermined area, including: according to the surface albedo data in the predetermined area, determine the cover classification data and the cover function index, wherein the surface albedo data is Multi-spectral data; determine the vegetation production rate index according to the surface reflectance data and surface temperature data in the predetermined area, where the surface temperature data is obtained from the inversion of thermal infrared remote sensing data; determine the terrain according to the surface elevation data in the predetermined area Moisture Index; and Determining Land System Status from Cover Classification Data, Cover Function Index, Vegetation Production Rate Index, and Topographic Moisture Index.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method, device and storage medium for assessing the state of a land system. Background technique [0002] Existing soil organic carbon estimation models and methods mostly select characteristic variables from the perspective of data mining and mathematical statistics. The interpretability of the results and the comparison of model results between different regions are poor, which is not conducive to the implementation of soil organic carbon management measures. practice. Second, the reliance on historical achievement data hinders the universality of the method, and the difficulty of updating historical achievement data also reduces the accuracy of estimation results. [0003] In view of the technical problems of the existing methods for estimating soil organic carbon content in the above-mentioned prior art due to poor data renewability, poor accuracy of esti...
