| 英文摘要 | Studying spatial and temporal variation of soil loss is of great importance because of global environmental concerns. Understanding the spatial distribution of soil erosion and deposition in the high-cold steppe is important for designing soil and water conservation measures. Measured Cs-137 losses (Bq m(-2)) from long-term high altitude (4,000 m above sea level) watershed plots on the Qinghai-Tibet plateau and derived soil erosion estimates (Mg ha(-1) year(-1)) were significantly correlated to directly measured soil losses from the same plots, over the same period (1963-2005). The local reference inventory was estimated to be 2,468 Bq m(-2). The result of analyzing Cs-137 distribution and its intensity in the soil profiles in this area shows similarities to Cs-137 distribution in other areas. Cs-137 is basically distributed in the topsoil layer of 0-0.3 m. Soil erosions vary greatly in the entire sampled area, ranging from 5.5 to 23 Mg ha(-1) year(-1), with an average of 16.5 Mg ha(-1) year(-1) which is a moderate rate of erosion. |
