Analysis of Land Use Change in Dingyuan County from 2008 to 2018

运用RS和GIS技术,对2008—2018年定远县土地利用变化进行分析。结果表明:近11年定远县土地利用类型的主要变化趋势为耕地和建筑用地的持续增加,林地和未利用地的持续减少;人类活动、土地整治政策和城镇化发展对定远县的土地利用类型变化及其空间结构有一定的影响,土地利用率不断提高,各地类之间存在相互转化,同时推动定远县城区布局从分散的城区中心演变到集聚性城区;定远县整体土地利用变化逐步向空间集约化和可持续化方向发展的同时,要合理规划设计城镇建设规模,更要注重发挥和保持资源尤其是农业资源的优势和产业地位。
