摘　　要：该文针对中国县级土地利用变更调查工作的实际情况,分别以山西省昔阳县和太原市尖草坪区为研究区,探讨了基于正射影像和GIS技术的土地利用变更调查方法。该方法的主要特点是发挥航空遥感技术的优势,把正射影像作为县级土地利用现状更新的主要数据源,在土地利用数据库的支持下,用GIS集成数据,从而建立一个准确把握县级土地利用现状及其变化的动态监测系统。According to Chinese status quo of land-use change survey, and taking Xiyang county, and Jiancaoping district, Taiyuan as study areas, this paper discusses the method for land-use change survey based on orthophoto and GIS. The characteristics of the above method are as follows: Giving full play to the superiority of aerial (remote) sensing technology, taking orthophoto as main datum source for updating county-level land use status quo, supported by land use database, and integrating data under GIS. A dynamic monitoring system which can grasp county-level land use status quo and change exactly was established.
