| Abstract: | Brahmaputra River basin was chose as a study area in this paper.Remote sensing and GIS technology were used to process remote sensing image of three periods in 2000,2005,2009 and extract soil and water loss factor.Soil and water loss dynamics in Brahmaputra River basin were studied deeply through the transition probability matrix.Markov model was used to predict dynamic changes of soil and water loss in Brahmaputra River basin.The result showed that the tend of soil and water loss was gradually increasing f... |
