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] The following is attached with the manual Figure 1-4 The present invention is further described in detail.

[0014] The invention discloses a method for measuring forest soil soil flow. The forest soil to be measured is trimmed to construct a soil profile that is convenient for measurement; multiple soil flow collection systems are arranged on the soil profile.

[0015] Soil profile production: Excavate the soil profile in the sample plot. The size is generally 150cm long, 100cm wide, and 50cm-100cm deep. The upper end of the hillside is vertically flattened as the soil flow collection surface, and the lower end of the hillside is made into a ladder 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 flow collection system 3 includes a collecting...

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, in particular to a method for measuring forest soil inflow. Background technique [0002] Soil inflow refers to the movement of water in the soil, including the vertical infiltration and horizontal lateral flow of water in the soil. Together with surface runoff and underground runoff, it constitutes the runoff process of the watershed and plays a very important role in the process of watershed runoff generation. Especially in the forest watershed, the surface soil has strong water permeability, and the rainfall can quickly infiltrate into the soil to form soil water, and flow down the slope to form soil inflow. Soil inflow can not only change the relationship between rainfall and runoff, and cause corresponding changes in surface erosion, but also affect the output characteristics of nutrients on the slope. Soil nutrients enter adjacent receiving water ...
