基于遥感与GIS的区域土地利用变化的动态监测与预测研究

THE DYNAMIC MONITORING AND PREDICTION OF THE REGIONAL LAND USE CHANGE BASED ON RS AND GIS

本文以广西苍梧县沙头、石桥两镇为例 ,利用航空遥感调查方法结合GIS技术 ,定量分析研究区域内土地利用动态变化过程 ,以及土地利用各类型之间的相互转化状况。运用马尔柯夫原理 ,建立齐次马尔柯夫链模型中的转移概率矩阵 ,对研究区未来土地利用演变趋势进行模拟与预测。

This paper takes the Shatou and Shiqiao towns in Cangwu County, Guangxi as an example. The dynamic evolution process of landuse and the transformation each other among all types of land use are analysed quantitatively with the help of RS and GIS. The evolution tendency of land use in future is simulated and predicted with Markov model in the study area.
