| 中文摘要: |
| 丘陵山区农业生产及农村经济发展水平直接关系到我国经济总量规模，是关系经济均衡发展的重大问题。以五指山市丘陵山区为例，基于Arcgis 平台构建耕地整治潜力基础信息数据库，以行政村为评价单元，在测算出耕地自然潜力的基础上，构建“生产能力—景观格局—基础设施—整理需求”的多因素综合评价指标体系，对其进行修正。同时运用熵权法、修正层次分析法确定耕地现实潜力修正的各因素指标权重，综合考虑主观和客观因素，确定耕地整理潜力大小，划分潜力综合分区。该研究方法有利于实现评价结果的动态化更新，评价结果更加客观贴近实际，具有一定的可行性，可用于指导宏观尺度土地整治战略安排和重大工程布局。 |

| This article aim to find a suitable method for the evaluation of hilly cultivated land potential，which can provide an assistant decision-making for the land consolidation project. Based on Arcgis platform and the advantage of DEM，we calculated the natural potential of arable land on the scale of the administrative villages，and established an evaluation system，which contained the factors of production capacity，landscape pattern，infrastructure and demand.Moreover，using the entropy weight method，the analytic hierarchy，both objective and subjective was determined， the real potential of arable land was measured. We established basic information database and a more comprehensive multifactor evaluation system. The research method can achieve dynamic updates，and the evaluation of the results is feasible and can be used to guide macro-scale land reclamation arrangements and major projects layout. |
