| 摘 要： | 根据南方红壤侵蚀典型区域--福建省长汀县1988、2000、2007年3个年份的遥感影像解译的土壤侵蚀数据,确定土壤侵蚀的初始状态矩阵和转移概率,应用马尔柯夫模型进行土壤侵蚀强度变化预测,结果与实际的误差通过了检验,模型在研究区的土壤侵蚀预测可靠.预测结果表明:研究区土壤侵蚀总面积2010年为40 031.76 hm2...

| Abstract: | Based on the data of soil erosion obtained from the RS images of Changting county in 1988,2000 and 2007,Fujian province,a initial state matrix and transition probability matrix of the soil erosion are worked out with the aid of ArcGIS9.0 and MATLAB software.Using the Markov chain model,the tendency of the soil erosion is predicted.With the x2 test,the models are suitable for prediction of the soil erosion.The results of calculation using the Markov chain model showed that soil erosion areas are 40 031.76 hm... |
