Abstract:: This paper expounds the application of Markov prediction model to examine the change of soil and water loss dynamics. And in this paper, taking Changting County as the study field in red soil degradation, using the TM image in 2000 and 2007 respectively, with the support of RS and GIS, it obtained the circumstances of changes of soil and water loss in the two periods of time, and predicted the changes of soil and water loss dynamics in 2014 with the Markov prediction model. The result showed the trend of soil and water loss in changting county is, to a certain extent, under control. Furthermore, ecological environment is becoming improved during the period of 2007 to 2014, because the total loss area and intensity were being decreased, serious intensity of loss and acute loss was not obvious. And according to the analysis by using Markov prediction model, it indicated that the soil and water loss was changing. This implied that human activity is the main cause to change. So the soil and water conservation task in red soil degradation was still arduous.
