基于TM影像和马尔柯夫模型的新疆精河县土地利用动态研究

Dynamic study on landuse based on TM images and Markov model in Jinghe County of Xinjiang

以新疆精河县为研究区,选择其1990年、1999年和2007年3期TM遥感影像数据,借助于"3S"集成技术,提取土地利用信息,得到3年中各土地利用类型面积.基于此结果,分别对1990～1999年和1999～2007年2个时段内的土地利用类型转移进行马尔柯夫过程分析,得到了研究区1990～1999年和1999～2007年的土地利用类型转移具有马尔柯夫性的结论,揭示了其土地利用类型转移的时空动态规律,进而为研究区及类似区域土地利用措施的调整提供重要的理论参考.

Abatract： Jinghe County of Xinjiang is selected as a study area and TM images of 1990,1999 2007 are choiced to obtain some information about its landuse such as landuse-type landuse area and etc.Based on these results,Markov process is analysed on the between differrent landuse types from 1990 to 1999 and from 1999 to 2007,respectively.And such a conclusion that the landuse transition is Markov process between both 1990 1999 and 1999 2007.And all these help to indicate the dynamity of landuse transition in order to give some important academic references to study area and other similar regions.
