摘要:

根据1999年土地利用动态遥感监测项目,利用TM和SPOT PAN影像对苏锡常地区1998~1999年土地利用动态进行监测,采用了多源信息叠加融合方法进行变化信息的增强,自动分类与人机交互结合方式进行变化的解译,得到该区域的土地利用变化情况,重点计算了该地区的耕地转移速率,得出工矿、城镇、公路是占用耕地的主要利用方式,城镇化水平仍很高。关 键 词:苏锡常地区;多源信息融合;土地利用变化中图分类号:TP 79

Abstract: Land Use Dynamic Monitoring for SuXiChangRegion by Remote SensingSUN Dan-feng(Land Resources dept.,China Agricultural University,Beijing100094China)ZHOU Guang-yuan,YANG Ji-hong(The Academy of Land Survey&planning of China,Beijing100081China)Abstract:According to the Land and resources Ministry project of 1999 land use dynamic monitoring byremote sensing, the SuXiChang region has been finished the land use change between 1998 and 1999 byusing the TM and SPOT PAN images .Adopting the multi-sensor data overlay and fusion method toenhance the change information, which mainly includes the image spatial correction, the IHStransformation and overlay method to fusion the TM and SPOT image, which enhances the changeinformation combining the spectral and textural characters, then creating the 1998 land use map and thechange image via the automatic classification method ,in which the no change pixel value is zero and changepixel value is one, and then using the visual interpretation aided by computer to determine the 1999 landuse type of change region. Combining the change region and 1998,1999 land use type to create the land usedynamic map, calculating the transfer velocity of arable land importantly and reached the conclusion-city,industry and roads were the main parts occupying the arable land ,the average velocity of arable landtransfer to industry in this region was 2.72‰,and the arable land loss was serious ,the rate of urbanexpansion was still high in this region. So establishing the SuXiChang region land use dynamic monitoringand warning system can acquire the land resource quantity and using information, necessary for landresource management. The method to enhance the change information and using the multi-sensor datafusion and automatic classification and visual interpretation only for change region improved the dynamicmonitoring speed and guaranteed the accuracy of the results.Key words:SuXiChang region, Multi-sensor fusion, Land use change
