Description

Technical Field

[0001] The present invention belongs to the technical field of slope runoff experiments, and particularly relates to a slope surface runoff experiment device for high plateaus and high slopes. Background Art

[0002] Currently, due to the influence of human activities, artificial interference has been caused to the watershed slope surface, thus having a greater impact on the formation and confluence process of slope flow. The response relationship between rainfall and slope runoff has become abnormal, exacerbating the occurrence of rainstorms and floods, and easily triggering hydrogeological disasters, causing huge economic losses. Therefore, people have set up some protection methods to protect the watershed slope surface, such as planting plants on the watershed slope or installing some protection facilities on the watershed slope surface. Among them, installing protection facilities is widely adopted because of its quickness and convenience. For example, some sand and vegetation mixed protection nets are installed on the watershed slope surface. These protection nets can effectively limit the influence of slope runoff. With the introduction of new biological technologies, some new slope protection devices with vegetation have been developed. However, the performance of these new protection devices needs to be tested before use. Summary of the Invention
