| 摘 要： | 为有效实现四川省生态环境的动态监测,运用RS、GIS和GPS技术,以2004年中巴资源卫星(CBERS-02)遥感影像数据为信息源,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;利用GIS技术的空间分析功能,提取出2000～2004年期间土地利用/覆被变化信息,得到2000～2004年期间四川省高精度的土地利用/覆被变化数据库。最后对四川省土地利用/覆被变化信息进行分析,对四川省生态环境的下一步研究指名了方向。 |

| Abstract: | To efficiently fulfill the dynamic monitoring on ecological environment in Sichuan province,based on RS(remote sensing),GIS(geographic information system) and GPS(globe positioning system),the dynamic changes of high precise land use and land cover changes can be acquired.Firstly,land use and land cover changes(LUCC) is interpreted according to the CBERS-02 image in 2004,and TM(thematic mapper) data interpreted in 2000.Secondly,the interpreted result from CBERS-02 is validated in the field through GPS receiver and the database is precisely updated.At last,the LUCC of high precision from 2000 to 2004 is extracted from the final database through the spatial analysis of GIS.The primary analysis is finished and the next research work is pointed out at the same time. |
| Keywords: | dynamic monitoring RS GIS GPS land use and land cover changes(LUCC) |
