摘要：以江西省抚州市东乡区中心城区为例，借助GIS平台进行建设用地适宜性评价。通过城市发展边界、基本农田连片度和耕地国家利用等三方面修正，且根据空间矛盾协调原则作出决策且优化协调城镇建设用地和农业生产的布局，并对城市开发边界进行划定。结果表明，建设开发适宜性值由高到低呈现为主城区及道路的分布空间，综合质量高的耕地主要分布在西部和东部。将综合建设用地重心移动分析等研究方法引入耕地国家利用等指标，不可调区布局冲突的空间决策为调整城市开发边界，优先保障耕地。可调区布局冲突的空间决策为调整耕地保护范围，优先保障城市发展。

Abstract： Taking the central urban area of Dongxiang district，Fuzhou city，Jiangxi province as an example，the suitability of construction land was evaluated by means of GIS platform. The boundary of urban development，the continuity of basic farmland and the national utilization of cultivated land were revised，and a decision was made according to the principle of coordination of spatial contradiction and the layout of urban construction land and agricultural production was optimized，and the boundary of urban development was delimited. The results show that the suitable value of construction and development is distributed in the main urban area and road from high to low. The spatial decision of non-adjustable area layout conflict is to adjust the urban development boundary and give priority to protecting farmland. The spatial decision of adjustable area layout conflict is to adjust the cultivated land protection scope and give priority to protecting urban development.

Key words： urban development; cultivated land quality; land use; central district in Dongxiang city

随着中国城市化的快速推进，城镇建设规模快速扩大，保护耕地与保障建设的发展之间矛盾日益尖锐[1]。依据资源条件、空间生态条件和环境条件，明确江西省抚州市东乡区国土开发的限制性，划定城镇和农业的空间开发管制界定[2]。城镇建设的适宜性评价是城市建设用地调整布局的前提，并指导土地利用规划结构调整，确定江西省抚州市东乡区土地的最适宜用途，将对城市的整体发展布局以及城市经济的发展产生重大的作用[3，4]。国内外学者主要采用CLUE-S、MCE-CA、人工神經网络和反规划[5]等模型方法从多个角度对城镇开发边界确定的划定进行探索[2]。……
