为建立四川省生态环境本底数据库,实现生态环境动态监测,运用遥感(RS)、地理信息系统(GIS)和全球定位系统(GPS)技术,以2004年中巴资源卫星(CBERS-02)遥感影像为信息源,2000年TM遥感影像解译的数据为基础,对2004年遥感影像进行动态变化解译,修改2000年数据库;手持GPS接收机,在野外对解译成果进行验证。更新数据库.最终建成四川省生态环境本底数据库;最后对四川省土地利用/覆被变化信息进行了分析研究,为四川省生态环境下一步研究指明了方向。
In order to establish the background database of ecological environment in Sichuan Province and realize the dynamic monitoring of the ecological environment, remote sensing (RS), geographic information system (GIS) and global positioning system (GPS) Based on the data from TM remote sensing image interpretation in 2000, the image was dynamically changed for remote sensing images in 2004, and the database of 2000 was revised. The handheld GPS receiver was used to verify the interpretation in the field. Finally, the background database of ecological environment in Sichuan Province was built up finally. Finally, the information of land use / cover change in Sichuan Province was analyzed and studied, which indicated the direction for the further study of ecological environment in Sichuan Province.
