摘　　要：[目的]分析2001—2010年江苏省南通市通州区耕地占补的时空特征,初步探讨县级土地利用总体规划对耕地占补的管控效果,为进一步改进土地利用总体规划的编制与实施提供科学依据。[方法]以通州区2001和2010年2个时期的土地利用动态数据为基础,采用GIS空间分析方法,分析该区2001—2010年耕地时空变化。[结果](1)2001—2010年通州区耕地总面积由92 503.47hm2减少到72 466.52hm2,补充速度慢于占用速度,占用和补充的水田比例都较高。(2)耕地占用的主要去向是建设占用,96.80%是农村居民点占用,耕地补充的主要来源是建设用地,水域及其他农用地,其中农村居民点整理补充耕地的比例为71.67%。(3)耕地占用主要集中在通州区西北部和中部地区,耕地补充主要集中于研究区中部以及北部地区。(4)从空间规模与空间结构控制效果来看,通州区土地利用总体规划在2001—2010年对耕地占补的管控效果较差,对具体地类而言,对新增城镇工矿占用耕地的管控效果要优于农村居民点用地。[结论]2001—2010年通州区耕地总面积减少,其占用的主要去向和补充的主要来源均是建设用地,且呈现一定的空间分布规律,土地利用总体规划对耕地占补的管控效果较差。[Objective] The aim of this study is to analyze the controlling effect of land-use planning on spatial-temporal change of cropland supplement from 2001 to 2010 in Tongzhou District, Nantong City, Jiangsu Province, in order to provide the scientific basis for the further general land use planning and implementation.[Methods] The GIS spatial analysis method and transfer matrix in 2001 and 2010 of Tongzhou District was used to evaluate the controlling effects of land-use planning on cropland occupation and supplement.[Results] （1） The area of cropland declined from 92 503.47 hm^2 to 72 466.52 hm^2, the supplementary speed was lower than the occupation rate, and the proportion of paddy field was higher in both occupation and supplement. （2） The main occupation of cropland was construction land, and 96.80% of which was the rural residential areas. The main resource of cropland supplement was construction land, water area and other agricultural land, 71.67% of which came from the rural residential areas. （3） The occupation of cropland mainly distributed in northwestern region and central region, while the supplement of cropland mainly distributed in central region and northern region of Tongzhou District. （4） Generally, the cropland occupation and supplement controlling effects in Tongzhou District are poor. The controlling effects of cropland occupied by newly-increased urban industrial and mining land are better than land use at the rural residential land.[Conclusion] The area of cropland has declined from 2001 to 2010 in Tongzhou District, and its main occupation and supplement is both the construction land, which presents some laws of spatial distribution. The land-use planning has a poor controlling effect on cropland occupation and supplement.
