Problems solved by technology

Due to the lag of research methods, the scope of research on the formation of soil inflow and nutrient loss is relatively small, and when it comes to specific nutrient loss, most of them are combined with surface runoff, and it is impossible to accurately and scientifically evaluate the relationship between soil inflow and nutrient migration. The impact of churn

Embodiment Construction

[0013] Attached below in conjunction with the instructions Figure 1-4 The present invention will be described in further detail.

[0014] A method for measuring the soil flow in the forest soil is to trim the forest soil to be tested to construct a soil profile that is convenient for measurement; a plurality of soil flow collection systems are arranged on the soil profile.

[0015] Soil profile production: excavate the soil profile in the sample site, the size is generally 150cm long, 100cm wide, and 50cm-100cm deep. The upper end of the hillside is flattened vertically as the soil midflow collection surface, and the lower end of the hillside is made into a stepped shape for easy observation ,sampling.

[0016] Multiple soil layers are formed on the soil profile 2, and multiple soil flow collection systems are arranged on each soil layer to complete the collection and measurement of soil flow in different soil layers.

[0017] The soil middle flow collection system 3 includes a coll...

Abstract

The invention discloses a method for measuring interflow in forest soil, and belongs to the field of forest soil ecological study. The method is characterized in that the system utilizes the soil profile and consists of an interflow flow collecting groove, a flow guide pipe and an interflow collector, wherein the flow collecting groove is embedded into a soil body in different layers of the soil profile, the interflow is collected, and the interflow is guided into the collector for completing the collection of the interflow. The method has the advantages that the structure is compact, the system is reasonable, the method is simple, the realization is easy, a scientific and reasonable small-dimension measuring system is provided for the study of the forest soil hydrology process, the moisture and nutrient balance and moving and the like, and greater popularization and application values are realized in the fields of forest soil ecology, forest hydrology, water and soil conservation and the like.

Description

Technical field [0001] The invention relates to the technical fields of forest soil ecology, forest hydrology and the like, and specifically relates to a method for measuring forest soil soil flow. Background technique [0002] Soil flow refers to the movement of water in the soil, including vertical infiltration and horizontal lateral flow of water in the soil. It forms the runoff process of a watershed together with surface runoff and underground runoff, and plays a very important role in the production of watershed runoff. Especially in the forest watershed, the surface soil is highly permeable, and rainfall can quickly penetrate into the soil to form soil water, and flow down the slope to form a soil flow. Soil flow can not only change the rainfall-runoff relationship, and cause corresponding changes in surface erosion conditions, but also affect the output characteristics of slope nutrients. Soil nutrients enter adjacent receiving water bodies through soil flow, causing cert...
