摘要
以1992年TM和2006年ETM+影像提取通海县土地利用信息,根据最佳指数因子(OIF)的最佳组合波段,在最佳组合波段下利用遥感图像处理软件ERDAS9.2选择监督分类方法,获取通海县1992～2010年土地利用/土地覆盖变化信息。结果表明:15a来该地区土地利用程度加强:耕地、建设用地显著增加,水域面积虽有萎缩,但变化不大;驱动土地利用变化的主要因素是人口增长、城镇化水平提高与经济的快速发展。
The land use data is taken for Tonghai County from the TM images of 1992 and the ETM ＋ images of 2006. Aecording to the optimum index factor （OIF） , within its best combination band, the supervised classifica- tion method is selected by using the remote sensing image processing software ERDAS 9. 2, and the information of the land use/land cover change in Tonghai County from 1992 to 2010 is obtained. The results show that the land in the area is under intensifying use for the past 15 years. The farmland and construction land is obviously increasing with lightly shrinking water area. The driving forces for this change are increasing population, urbanization and fast economic development.
