摘　　要：研究目的:为了对比矢量数据和栅格数据在土里利用过程中的差别。研究方法:借助于Super Map2008、MATLAB R2009a、Arc GIS9.2和IDRISI Andes15.0等软件,建立马尔科夫模型,得到转移概率矩阵进行对比分析。研究结果:矢量数据的结果一般更为精确,但软件利用程度低。栅格数据的结果比较而言没有那么精确,但是思路简单,软件利用程度高,结果易得且也能满足预测要求。研究结论:不论是矢量数据还是栅格数据都可以很好地用于土地利用中的预测。This paper tried to compare the differences of vector data and raster data used in the land utilization.It made the Markov model by means of SuperMap2008,MATLAB R2009a,ArcGIS9.2and IDRISI Andes15.0,etc.,and got the transition probability matrix to analyze the discrepancy.Results showed that the vector data was more accurate,but the software-use degree was more lower than raster data.Raster data was relatively less accurate,but the ideas were simple,and the utilization degree of software was high,which was easy to get and also can satisfy the requirement of forecast.Both vector data and raster data can be well used in the prediction of land use.
