摘要
以1992年、2000年和2009年大冶市TM影像数据为基础,利用ERDAS遥感图像处理软件的监督分类方法和ArcGIS的空间分析功能,对大冶市水域、建设用地、林地和耕地四大土地利用类型进行提取。随着城市化进程脚步的加快,城市建设用地的扩张,土地的不合理利用和污染,使大冶市耕地面积呈日趋减少的趋势。通过土地利用变化情况的综合分析,提出更具实践性的建议,从而更好地指导大冶市土地利用规划的制定。
Taking the year of 1992＇s, 2000＇s and 2009＇s TM image data of Daye as a foundation, on the based of the use of supervised classification methods in remote sensing image processing software ERDAS, and the spatial analysis function of ArcGIS, the article extracted the four major land use types of DAYE city, which included waters, construction lands, woodland and cultivated lands. With the accelerated pace of urbanization, urban construction land expansion, the irrational use and pollution of land, so that the cultivated area of Daye was in declining trend.
