摘　　要：针对具有明显区域特征的石河子垦区,基于Landsat TM图像设计了石河子垦区农用地变化遥感监测技术路线。通过实地调查和以2000年、2008年2时段TM影像为基础开展的研究区农用地遥感监测研究,探讨了垦区农用地变化遥感监测中分类系统的拟定、信息提取与表达、线状地物的扣除及变化数据的分析处理等关键技术环节,并全面分析了研究区土地利用的变化特征和利用程度,阐明了研究区土地利用变化的区域特点。结果表明,基于Landsat TM图像的石河子垦区农用地变化遥感监测研究效果较好。A technological method was designed of the farmland change investigation of Shihezi reclamation area by remote sensing using Landsat TM image.Applying 2000 and 2008 Landsat TM images as data sources of Shihezi reclamation area,the paper studied the farmland change by investigation,with emphasis placed on such key techniques as classification categories,information extraction and representation of the change,acreage deduction of linear features,and flow chartofdata processing.The quantity change model of farmland and its spatial variation characteristics in the area were analyzed comprehensively,and elucidated the district features of farmland change.Monitoring results show that the study was carried out on the farmland change investigation of Shihezi reclamation area by remote sensing using Landsat TM image with a preferable result.
