摘　　要：以江苏省泗阳县为例,利用GIS空间分析技术,通过土地农用适宜性分区的方法,将泗阳划分为农用适宜1~4级区,并叠合现状耕地进行筛选,提出永久保留的耕地、阶段保留的耕地和可非农化转用的耕地等空间布局方案,研究结果显示,3类耕地面积分布为516.5 km2、136.8 km2和27.2 km2,占现有耕地面积的75.9%、20.1%和4.0%。Taking Siyang County as an example,and by using GIS spatial analysis technology,moreover,based on the regionalization method of suitable development of agricultural land use,Siyang was divided into four sub-regions：the first-forth suitable regions,then,combined with the screening of the plough current situation,the spatial distribution schemes,such as permanent reserved area,stage reserved area and non-agriculture transmission area,were put forward.The results indicated that three regions areas are 516.5,136.8 and 27.2 km2,respectively,which accounted for 75.9%,20.1% and 4.0% of the existing agricultural acreage.
