Prof. Dr. Baoyuan Liu, School of Geography, Beijing Normal University. His research fields include soil erosion process and modeling, soil erosion monitoring, and on-site and off-site soil erosion risk assessment. So far, he has published more than 100 research papers with a h index of 38, and all the publications have been cited nearly 6000 times. Dr. Liu received his Doctoral degree in Soil Science from the Institute of Soil and Water Conservation, Chinese Academy of Sciences in 1990, and visited the National Soil Erosion Research Lab in Purdue University as a post-Doc during 1993-1996. He was appointed as the Director of the State Key Laboratory of Soil Erosion and Dryland Farming on the Loess Plateau in 2016, Northwest A&F University, Chinese Academy of Sciences. Since 2018, Dr. Liu has served as an Associate Editor of CATENA. Dr. Liu’s major academic contributions and awards include: (1) Developed the Chinese Soil Loss Equation (CSLE) by parameterizing the gradient factor of steep slopes and other soil conservation factors. The CSLE has proved to be more accurate and practical for use in China than the Universal Soil Loss Equation (USLE). (2) Organized the National Soil Erosion Survey during 2010-2012 and applied the CSLE to produce the first water erosion intensity map of China. (3) Developed standard protocols for soil loss measurement at plot and watershed scale, for which he awarded the status of National Outstanding Researcher. (4) Calibrated and validated the runoff parameters in WEPP for which he received an award from the US Department of Agriculture.
