摘要
运用RS,GIS和GPS技术,以2005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2005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2000-2005年土地利用/覆被变化本底数据库;最后对四川省土地利用/覆被变化信息进行分析,并为四川省生态环境下一步研究指明了方向。
Based on remote sensing(RS),geographic information system(GIS) and globe positioning system(GPS),the land use/cover changes(LUCC) databases can be acquired.Firstly,the LUCC was interpreted according to the CBERS-02 image in 2005,in the light of the database interpreted from thematic mapper(TM) in 2000.Secondly,the interpreted result from CBERS-02 was validated in the field with GPS receiver and the database was precisely updated.Thus,the LUCC databases of Sichuan province from 2000 to 2005 were established.At last,the primary analysis was finished and the next eco-environment research work is pointed out at the same time.
