摘　　要：城市扩张对耕地压力具有重要影响,为探究两者在微观层面的协调状况,将宁波市鄞州区作为靶区,利用2005、2011年两期土地利用数据及对应统计年鉴,构建城镇扩张与耕地压力协调模型,采用分类对比法解析鄞州区各镇(街)城镇化水平与耕地压力协调的变化态势。研究发现:(1)受地形与规划影响,鄞州区城镇化水平提升区域性分布明显;耕地压力总体呈上升趋势,但呈现多样性变化;城镇扩张与耕地压力协调状况亦受规划影响;(2)城镇扩张与耕地压力上升存在协调关系;土地利用类型转换对其有较大影响;(3)促进城镇扩张与维持耕地压力平稳存在可能;(4)在承接中心城区的辐射时,应当注意土地节约利用。这些发现可为其他地区合理进行城镇建设提供参考。Urban expansion has very important influence on cultivated land pressure. Yinzhou district is treated as the target area to explore the coordination status of the above two issues in the micro-level. The land use data of 2005 and 2011 and relevant statistical yearbooks are used to construct the coordination model between urban expansion and cultivated land pres- sure ; and class comparing methods is used to analyze the changing trend of the urban expansion and cultivated land pressure in each town of Yinzhou district. The results are as follows ： （ 1 ） influenced by the terrain and planning, the level of urbani- zation of Yinzhou district improves differently in different regions;Cultivated land pressure increases in general,while plan- ning changes variably. （2） Coordination relation exists between urban expansion and cultivated land pressure increase;land use type conversion contributes a lot. （3） it is possible to balance the urban expansion and cultivated land pressure in- crease. （4）While undertaking the radiation of the central city,economical land use should be paid more attention to. All of the above results can be the references towards urban construction of other regions.
