ActiveCN121632985BEliminate distracting factorsincrease reflectionClimate change adaptationColor/spectral properties measurementsSoil scienceSpatial heterogeneity
This invention relates to the field of soil monitoring technology, specifically to a method, equipment, and system for determining the physicochemical properties of terraced soil. The method involves acquiring spectral data from various monitoring points in the terraced fields at different times and in both in-situ and experimental environments. Given the spatial heterogeneity of the physicochemical properties of terraced soils, the method analyzes the intensity differences and similarities of spectral peaks at different monitoring points under each environment, determining similarity indicators and clustering them to obtain clusters. Since soil nutrient changes are reflected in the spectral data, the method analyzes the fluctuation characteristics of spectral peak differences at different times within each cluster under each environment to determine soil nutrient fluctuation indicators. Because the experimental environment is relatively controllable, a target straight line is fitted based on the experimental data as a reference for in-situ spectral correction. Finally, by combining the differences and numerical characteristics of soil nutrient fluctuation indicators at monitoring points within the clusters under in-situ conditions, in-situ environmental parameters, in-situ spectra, and the target straight line, the in-situ spectrum is corrected, thereby improving the accuracy of soil nutrient element determination.
