| Abstract: | Based on the data of third soil erosion census, analysis is made on the general condition of water and soil erosion at present, including water erosion, wind erosion and freeze-thaw erosion, as well as soil and water losses situation in four economic regions of east, northeast, middle and west China. Dynamic changes of soil erosion in the past 15 years are examined with the data of censuses collected by the Ministry of Water Resources. Evaluation of soil losses changes over years in major fiver basins of China is also conducted. |
