| 摘 要： | 为掌握并有效监测土地利用,以绵阳市遥感影像、地形图、土地资源分布图为基础资料,利用ERDAS软件对2000和2005年两期影像进行校正、配准、融合等处理,土地利用分类精度从84.5%提高到92.3%。结果表明:耕地、牧草地、水域面积减少,但减幅不大;居民点及工矿用地、交通用地增加较快;未利用土地大幅减少。可见绵阳市在城市高速发展过程中的土地利用正在日趋合理化。

| Abstract: | In order to master and monitor the situation of land utilization effectively, two images in the year of 2000 and 2005 were adjusted, matched and fused using ERDAS software based on Mianyang city's remote sensing image, topographic map, and land resources distribution map. Classification accuracy of land utilization is improved from 84.5% to 92.3%. The result indicates that the area of cultivated land, grassplot, and water area has decreased a little; the area of residential land, coal mine and traffic land has increased quickly; unused land has decreased greatly. It can be seen that Mianyang city's land utilization is rationalizing day by day in the process of high development. |
