摘  要:
[目的]研究龙泉市城市化进程中土地利用变化情况。[方法]采用2001和2010年ETM+影像作为数据源,运用Flaash大气校正法和重采样几何校正法对2期影像进行预处理,并通过最大似然法对龙泉市区进行土地利用分类,最后利用现状分类图和土地利用转移矩阵分析龙泉市区的土地利用变化情况。[结果]2001和2010年研究区农田大量减少,主要去向是森林、建筑用地和裸露地;建筑用地迅速增加,分布类型从分散变为集中;森林覆盖率有所提高。[结论]研究结果为龙泉市合理利用土地资源提供了一定的参考。

摘  要:
[Objective] The research aimed to study the land use change in urbanization process in urban area of Longquan City. [Method]Using remote sensing images of 2001 and 2010 acquired by ETM + sensor as data sources,methods of Flaash atmosphere calibration and Resampling geometry calibration were adopted to preprocess the images,then the urban land of Longquan City was classified with the method of Maximum Likelyhood,ultimately land use changes were analyzed with transfer matrix. [Result] From the year 2001 to 2010,farmland reduced in a large number and the reduced farmland has mainly transformed into urban construction,forest and bare ground; the land use of urban construction increased rapidly and its distribution type has changed from dispersal to concentration; forest coverage rate has increased a little. [Conclusion] The research provided a certain scientific reference for the rational use of land resources in Longquan City.
