摘要
本文根据安徽省岳西县１９５８－１９８２－１９９２年三个时期的遥感资料所编制的土壤侵蚀图，用点数转化法定量地分析岳西县上述两个阶段侵蚀演变和浸蚀类型之间的相互转化状况，确定相应的初始状态下（１９５８和１９８２）的转移概率矩阵，应用马尔科夫过程摸拟和预测岳西县土壤侵蚀及其格局的动态演变过程和未来演变趋势。
Based on the soil erosion maps from remote sensing data at 1958-1982-1992 periods,the development of soil erosion and the transitions among soilerosion types in Yuexi of Anhui are quantitatively analysed during those two peri-ods.The transition probability matrices at two primary states(1958 and 1982)are establised with Point-Transition-Method.Then,the development and the futuretendency of soil erosion and its patterns are simulated and forecasted with Markovprocess.
