摘要
选取宜兴市为研究区,在GIS和RS技术的支撑下,对农村居民点用地的规模变化和空间分布进行分析,对引起农村居民点用地变化的驱动因素进行研究。结果表明:1农村居民点用地整体呈下降趋势,变化速度逐年减慢,主要新增来源是农用地,主要转移去向是城镇建设用地;2在地形平坦、距离水源和农用地较近的地区,农村居民点分布密集;3经济发展、人口减少、交通改善和城市化水平提高是影响农村居民点变化的主要驱动因素。
Yixing City was taken as research area in this paper. In the support of RS and GIS technology, scale and spatial distribution change characteristics of rural residential land were analyzed, the driving factors which caused rural residential land change were studied. The results showed that： ① the scale of rural residential land showed decline trend overall, the speed slow down year by year, major new source of rural residential is agricultural land, and the major whereabouts is urban construction land; ②the rural residential was more intensively distributed in flatter area and nearer from water or agricultural land; ③ economic development, population, traffic improvement and urbanization level were main driving forces of rural residential changes.
