[0002] The runoff plot refers to a certain representative runoff field, a natural closed watershed or a closed artificial enclosure land plot without horizontal water exchange with the surrounding. Generally, the terrace is artificially developed and constructed, and the terrace surface and the terrace wall are relatively regular, which is different from most irregular slopes. The runoff plot on the terrace is relatively regular, which is mostly rectangular or prismatic. The constructed plot area is from tens to hundreds of square meters.

[0003] The runoff plot is the main scientific research facility and test method used by scientific researchers to study the law of surface rainfall-runoff-soil erosion. The terrace runoff plot can be used to study the hydrological process of the terrace ecosystem. The observation data plays an important role in the prediction and analysis of the law of ground water and soil loss, small watershed water and soil loss, and watershed planning.

[0032] During rainfall, the runoff and the sediment carried by the runoff generated by the monitoring area 1 flow from the high position to the low position until flowing into the sedimentation tank 3; in the sedimentation tank 3, the sediment gradually deposits and thus remains in the sedimentation tank 3, while the water flow continues to flow to the low position of the sedimentation tank 3, i.e. continues to flow to the water outlet, and then flows to the collection barrel 5 in sequence through the water outlet and the pipeline, for collection; the filter cloth 4 is arranged to prevent the sediment in the runoff from flowing out through the water outlet, thereby effectively ensuring that all the sediment can remain in the sedimentation tank 3; in this way, the lost water and soil are effectively collected and separated. Subsequently, only the sediment in the sedimentation tank 3 needs to be collected and weighed, and the water in the collection barrel 5 needs to be measured, and after calculation, the accurate result of the water and soil loss in the monitoring area 1 can be obtained, thereby effectively improving the accuracy of the data and ensuring the accuracy of the scientific research.

[0033] In the embodiment, the sedimentation tank 3 is provided with a water inlet on the side close to the baffle 2, and the runoff and the sediment generated by the monitoring area 1 flow into the sedimentation tank 3 through the water inlet during rainfall; the top of the sedimentation tank 3 is provided with a cover plate 6, which effectively prevents rainwater from directly entering the sedimentation tank 3 during rainfall, thereby affecting the monitoring result.
