摘要: 介绍了在RS与GIS支持下,以Landsat TM和ETM及SPOT数据为主要信息源,采用栅格数据与矢量数据、多源与多时相数据、遥感数据与生态环境基础图件相结合和内业处理与外业调查相结合的技术路线,应用遥感信息提取技术和遥感影像处理及DOM制作方法,得出近15 a辽宁土地面积变化及趋势。结果表明:近年辽宁耕地、水域和工矿等用地面积逐年上升;湿地、草地和未利用土地面积逐年下降。

Abstract: Based on remote sensing(RS) and geographical information system(GIS),Landsat TM,ETM and SPOT images,the raster and vector data and multi-source and multi-temporal remote sensing data as well as ecological environment basic maps were employed in order to investigate the dynamic changes of land use in Liaoning province during recent 15 years.At the same time,remote sensing information extraction technique,remote sensing image processing and DOM method were applied.The results showed that cultivated land areas,water areas,industrial and mining land areas increased year by year,while the wetland areas,grassland areas and uncovered land areas decreased year by year.
