Effect of land use and land cover change on soil erosion and the spatio-temporal variation in Liupan

Bin QUAN, M. J. M. R?MKENS, Rui LI, Fang WANG, Jie CHEN

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 4,   Pages 564-572 doi: 10.1007/s11783-011-0348-9

Abstract: To present the relationship between land use/cover change and spatio-temporal variation of soil erosionSoil erosion by water was the dominant mode of soil loss, while soil erosion by wind was only presentThe degree of soil erosion was classified into five severity classes: slight, light, moderate, severewith 146552 ha (8.8%), and very severe erosion by 97067.6 ha (5.8%).Soil erosion was severe on grassland with a moderate or low grass cover and on dry land.
