Rapid soil classification and identification method and system based on electromagnetic wave speed

The invention provides a rapid soil classification and identification method and system based on electromagnetic wave speed. The method comprises the following steps: acquiring electromagnetic wave speed and water content of to-be-detected soil; constructing a point location coordinate based on the electromagnetic wave speed and the water content, and obtaining a region where the point location coordinate is located according to a pre-constructed region division model; wherein the construction of the region division model specifically comprises the following steps: acquiring electromagnetic wave velocity sample data of different types of soil under different water contents; the method comprises the following steps: interpolating adjacent different types of soil sample data to obtain boundary control points between different types of soil, fitting the boundary control points to obtain a regional boundary, and constructing a regional division model based on the obtained regional boundary; and based on the obtai
