摘要
以长沙市中心区为例,采用RS和GIS技术对1991、1998、2004年3期TM数据进行处理,得到研究区土地利用现状图;在分析土地利用现状的基础上,采用Markov模型对研究区未来一段时期内土地利用变化格局进行了预测与分析。结果表明:2004～2017年,研究区土地利用变化趋势为:建设用地增加90.00%,林地增加9.25%,水域减小19.16%,耕地减小25.89%,未利用地减小0.91%。
Based on RS and GIS techniques, Land use/cover map was acquired through dealing with the three remote sensing images of the centre region of Changsha City in 1991, 1998 and 2004. Based on the analysis of the land use status, Markov model was applied to forecast the land use change of the centre region of Changsha City in the next few decades. The results indicate that, from 2004 to 2017, the area of construction land and forest land will increase by 90.00% and 9.25% ; water area, arable land and wasteland will decrease by 19.16% , 25.89% and 0.91% .
