[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 hm² to 72 466.52 hm², 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.
