摘 要: 以沛县2000,2004,2006年3期专题制图仪(thematic mapper, TM)影像和专题地图、统计资料为数据源,在ENVI,ArcGIS等软件的支持下,基于遥感(remote sensing,RS)和地理信息系统(geographic information system,GIS)技术研究沛县近6年来土地利用变化特征,得到沛县地区2000年至2006年土地变化情况及其土地利用变化转移矩阵。结果表明:在2000年至2006年期间,沛县土地利用类型变化幅度较大,在耕地大量减少的同时,居民和工矿用地大量增加,园林林地面积有所增加,水域和未利用土地的面积都在不断减少。发生这种变化的主要驱动力是人口大量增加、经济发展、政策变化及城市化的推动等。
关 键 词: 地理信息系统;遥感;土地利用变化;转移矩阵;驱动力

Abstract: Taking the thematic mapper (TM) image of 2000, 2004 and 2006 and the thematic map, statistic data of Peixian county as data source, the land use change characteristics in the past 6 years were studied based on remote sensing (RS) and geographic information system (GIS) technology, with the support of ENVI, ArcGIS and other software. The results showed that during the period of 2000 to 2006, the change of land use types in Peixian county had been in large amplitude, with the large reduce of arable land, the habitation, industrial and mining land had been increasing massively in the meantime; while on the contrary of the forestland’s slightly increased, water land and the unutilized land had decreased gradually. The main driving forces for this land use change were the increased population, the economic development, the policy changes, the promoting role of urbanization and so on.
Key words: geographic information system; remote sensing; land use change; transfer matrix; driving forces
