The hillside is a basic unit of 'source area' of material migration and watershed hydrological response, is also a basic module of a plurality of hydrological models and a main research object of hydrological processes, and finds out that the migration of water on the hillside can provide theoretical basis and scientific and technological support for the management, development and utilization of water resources on slopes, areas and watersheds. In mountainous forests, shrubs and grasslands, rainfall reaches the soil surface after passing through a forest canopy layer, a shrub layer, a herbaceous layer, a dry branch and fallen leaf layer and the like, and part of the rainwater flows downwards from a slope on the ground surface to form surface runoff; some of the water infiltrated into the soil is infiltrated into the soil, and some of the water infiltrated into the soil is infiltrated into the deep layer of the soil to reach the subgrade layer, some of the water is stored in the soil, and some of the water flows down along the slope in the soil, so that the interflow is formed.

In the past, most of researches on interflow are to establish a standard runoff field to collect the interflow, and the method is labor-consuming and time-consuming and relatively large in disturbance to soil. In order to avoid disturbance of a test on soil, some novel devices which are convenient for collecting soil interflow of mountain land soil appear in the prior art, however, the devices only have a collecting function, and subsequent quantity measurement needs to be completed manually and independently, so that data acquisition errors are large, and time and labor are consumed; meanwhile, the collecting device can involve a filter structure for separating water and soil, but after the filter structure is used for a long time, pores are blocked, so that an interflow collecting error is caused, and the measuring accuracy is influenced.
