Root stone structure-containing rock-soil body slope surface moisture movement simulation device and experimental method

Abstract

A root stone structure-containing rock-soil body slope surface moisture movement simulation device mainly comprises a box body, the top surface of the box body is a slope, the slope surface inclination is 30 DEG, the two end surfaces, the bottom plate and one side surface of the box body are cement outer walls, the two end surfaces are respectively positioned at the upper end and the lower end ofthe slope of the top surface, and the other side surface is a glass observation wall; the box body is sequentially segmented from the highest end to the lowest end, and the depth of each segment is gradually increased in sequence; a water outlet is reserved in the bottom of the lowest part of each section of the box body and is provided with an effluent liquid collector; each section in the box body is provided with a backfill soil layer; a soil moisture probe and a soil solution collector are arranged in each backfill soil layer; and earth surface vegetation is planted on the surface of the backfill soil layer, and high-definition cameras are sequentially arranged outside the glass observation wall.

Description

technical field [0001] The invention relates to the technical field of soil slope hydrology, in particular to a water movement simulation device and an experimental method on a rock-soil body slope with root stone structure. Background technique [0002] On slopes covered by vegetation for many years, plant root pores are the main biological factors that form soil preferential flow channels, and the strong spatial heterogeneity of gravel distribution and morphology increases the complexity of soil water movement processes. The impact of traditional soil hydrology research paradigms on root-stone structure is still insufficient, but the water movement process of root-bearing rock and soil is complex, which is the main process affecting solute migration and ecological environment in mountainous areas. Therefore, the research on the water movement, especially the preferential flow, of rhizolithic soil has become the focus and difficulty of forest soil hydrology research. At th...
