土地动态监测中遥感与地理信息GIS技术探析

Analysis of GIS Technology of Remote Sensing and Geographic Information in Land Dynamic Monitoring

城镇化发展中人地矛盾越发突出,为缓解这一矛盾,合理开发和利用土地资源十分重要,国家越发强调土地监测及保护的重要性,陆续运用了很多新技术,以促进动态监测。遥感与地理信息GIS为现代化技术产物,其融合了计算机技术、定位技术等,能在监测过程中实现精确定位,帮助有关部门掌握现下的土地利用情况,并预测未来的土地利用趋势。因此,本文就遥感与地理信息GIS技术在土地动态监测中的应用展开讨论。

The contradiction between human and land is becoming increasingly prominent in the development of urbanization.In order to alleviate this contradiction,reasonable development and utilization of land resources are very important.The country has placed more emphasis on land monitoring and protection,and has successively applied many new technologies to promote dynamic monitoring.Remote sensing and geographic information GIS are modern technological products that integrate computer technology,positioning technology and other technology.They can achieve precise positioning during the monitoring process,help relevant departments grasp the current land use situation,and predict future land use trends.Therefore,this paper discusses the application of remote sensing and geographic information GIS technology in land dynamic monitoring.
