摘要：Large catchment basins (the Yenisei,Angara, Lena, Selenga, and Amur) within southern East Siberia are characterizedby weak gully dissection, and by a very uneven distribution of gullies.The varied natural conditions, combinedwith anthropogenic impacts, produce a highly mosaic pattern in the spatial distribution of gullies.For the last 230–300years, four intensification stages of gully erosion were identified, which were associated with periods of abrupt changes innature management.The growth rates of the gully heads in different areas of southern East Siberia vary from 0.1 to 26myr–1, the mean long-term linear growth rates of gullies are 0.5–2.5myr–1.Extreme meteorological phenomena: torrentialrains (over 30 mm hr–1), abundant rains (over 50 mm day–1), and rapid snow thawing in the spring are responsible forgullying.
