Abstract

The invention discloses a soil saturated hydraulic conductivity measurement system and method, electronic equipment and a storage medium. The system comprises a constant-flow water supply module, a linear source distribution module, a soil storage module, an image acquisition module and a data processing module, the constant-flow water supply module is connected with the linear source distribution module and is used for supplying water to the linear source distribution module at a constant flow and monitoring the water flow output at the current moment; the linear source distribution module is located above the soil storage module and used for enabling water flow from the constant-flow water supply module to flow into soil in the soil storage module in a linear source mode. The image acquisition module is used for acquiring soil wetting front images at multiple moments; the data processing module is used for determining the soil saturation hydraulic conductivity according to the soil wetting front images at the multiple moments. Under the action of the linearly distributed water flow, the soil saturation hydraulic conductivity can be obtained after the picture of the wetting front is shot to obtain the soil wetting front images at multiple moments, and simple and accurate measurement of the soil saturation hydraulic conductivity is realized.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a soil saturated hydraulic conductivity measurement system, method, electronic equipment and storage medium. Background technique [0002] Soil saturated hydraulic conductivity is an important parameter in hydrological models and simulations of soil-vegetation-atmosphere processes. It refers to the soil water flux or seepage coefficient per unit soil water potential gradient when all soil pores are filled with water. Soil saturated hydraulic conductivity is one of the important physical properties of soil, one of the indispensable parameters in the study of soil water movement, and also an important number for studying the water balance of ecosystems. Distribution relations have an important impact. It can reflect the infiltration performance and seepage properties of the soil, and is a decisive factor for the acquisition of unsaturated hydraulic conductivity. Its accurac...
