| 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. |
