Abstract: In order to accurately grasp the current application status of soil and water conservation monitoring equipments, and solve the common problems in the research of soil and water conservation monitoring equipments such as low conversion rate, low automation, high price, demanding maintenance, and separation between research and practice, based on the CiteSpace knowledge map and a large number of experimental studies, this paper carried out a detailed summary analysis on the current application status and research progress of the current soil and water conservation automatic monitoring equipment. We introduced an automatic monitoring equipment for runoff and sediment and an automatic monitoring equipment for soil erosion. For the sediment and flow measurement, the relative error of the sediment amount measured by the new equipment and the true value is within 7.8%, and the relative error between the measured runoff and the true value is within 4.1%. For soil erosion measurement, the accuracy of the newly developed equipment is below 0.3 cm, as it can eliminate the large measurement errors caused by soil surface water and slope runoff. The newly developed equipment has simple structure, low cost and strong promotion prospects.
