摘要: 准确把握县级土地利用及其变化状况具有重大意义。结合国家“九五”重点课题“包头市郊区县土地利用动态监测技术系统”,介绍了遥感、全球定位系统和地理信息系统在县级土地利用动态监测中的集成理论和方法。研究结果表明,遥感发现了全县土地利用变化靶区的962%;GPS的数据采集方法、“假54”解算方法和“2D异常数据”处理方法提高了数据精度和处理效率;相对于传统的土地变更调查方法,整个系统带来了20多倍的质量—经济效益。最后讨论了建立地区RS判别模型、多时态地理信息系统等问题。

Abstract: It is of vital importance to accurately mastering county level landuse status and its changes.In the light of “Technological System for Dynamic Monitoring Landuse in Jiqoqu County of Baotou”,a key project of the Ninth Five Year Plan period,the integration theory and implementation methods of Remote Sensing,Global Positioning System and Geographical Information System that are used in dynamic monitoring county level landuse are introduced.Results indicated that 96 2%of the changed target areas were found by RS.The data acquiring methods,“pseudo 54” algorithm and “2D abnormal data” processing method can effectively prompt the efficiency of both field and laboratory work,and improve data precision.Contrasted with traditional investigation method of landuse changes,the entire system brings a qualitative economic benefit by over 20 times.Finally,questions concerning the establishment of RS interpretation model and TGIS are discussed.

Key words: S, landuse, dynamic monitoring
