| Soil texture affects soil water content and fertilizer and air permeability, and drives multiple physical and chemical processes occurring in the soil. Developing efficient and fast remote sensing technologies to predict the spatial distribution of soil texture has important theoretical and practical applications in soil quality evaluation and agricultural production planning. This paper discusses the application of remote sensing data, methods and models to predict soil texture, and the use of auxiliary data such as radar, terrain, and vegetation index data for soil texture prediction by remote sensing. The paper also proposes three methods for predicting the spatial distribution of soil texture based on remote sensing characteristics; namely, spectral response, characteristic wavelength selection, and remote sensing interpretation. It also focuses on the application effects of statistics, geostatistics, and machine learning models combined with remote sensing on spatial prediction of soil texture. The advantages, disadvantages, and application of several typical methods are compared, and the application conditions and accuracy verification methods of remote sensing prediction of soil texture are analyzed. Future research needs to focus on in-depth extraction of various remote sensing spectral features, acquisition of multiple types of environmental variables by remote sensing technologies, and development of a multi-algorithm hybrid model combining soil physical properties and data-driven machine learning features, so as to provide a basis and technical support for the spatial prediction of soil texture at different regional scales. |
