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...
