摘要
以四川省2000-2004年生态环境动态监测项目为基础,对中巴资源二号卫星(CBERS-02)遥感数据的处理方法和技术流程进行了分析和讨论,并探讨利用CBERS-02卫星遥感图像,结合G IS技术实施快速、准确、经济的大范围土地利用/覆盖状况调查.通过对遥感图像处理和信息提取,查明了研究区2000-2004年期间土地利用/覆盖状况及其动态变化.结果表明,CBERS-02卫星数据可以在土地利用/覆盖动态监测中发挥重要作用,通过与其它遥感资料和实测数据相结合,可以缩短监测周期,降低应用成本.
Based on the environmental dynamic monitoring item from 2000 to 2004 in Sichuan province, this paper analyzes the proceeding means and technology flow of the CBERS-02 image data. It discusses to carry out the rapid and exact investigation for the land use/overlay status by CBERS-02 image data and GIS. By the image process and interpretation, the land use dynamic change informarion is picked up and the background database of the land use is founded. This research shows that the CBERS-02 data has good application prospect in the aspects mentioned. The monitoring period will be shortened and the cost will be reduced by combining CBERS-02 remote-sensing data and in-situ measurement data.
