摘 要 农村问题和土地问题是中国政治、经济、社会等各个领域建设的中心内容，连云港市地处苏北，农村居民点的布局不尽合理，农村发展空间巨大，用地整理和布局优化对农村土地挖潜、农村建设等有着十分积极的意义。 本文基于 ArcGIS 软件系统，利用全国土地第二次调查数据和连云港市统计年鉴等数据资料，通过统计分析和空间分析，对农村居民点数量、规模做出详细统计。通过选取主要影响因素有自然、经济、社会和环境四方面要素，对农居点区位适宜性等级进行划分，根据九分制原理，确定了连云港市辖区内农村居民点空间布局适宜性综合得分。据此，将农居点整理类型分为城镇转化型，城乡联合型，发展型，限制发展型，迁弃型；利用同样的方法，分析得出连云港市辖区内农村居民点的扩展限制因素，并对其限制等级进行划分，为Ⅰ级区～Ⅴ级区。 通过对优先等级和限制等级的对比，结合研究区域具体特点，优先发展适宜性高且限制性低的发展区域，得出了连云港市辖区内农村居民点空间布局优化方案。 37424

Abstract Rural and land issues are central to all areas of the construction of China's political, economic, social, etc. Lianyungang City is located in northern Jiangsu, the layout of rural settlements is not reasonable, there will be a huge rural development in rural, land consolidation and layout optimization could tapping the potential of rural land use. Rural construction has a very positive meaning. Based on the ArcGIS software system, using the data of second national land survey and statistical yearbooks of Lianyungang. Statistical analysis and spatial analysis display the number of rural settlements, the scale to make detailed statistics. We selected four aspects of the main factors including natural, economic, social and environmental .The regional agricultural settlements suitability level is pided, according to the nine-point principle, then we determine the Lianyungang municipal districts of rural residential space layout Suitability score. Accordingly, the consolidation type of agricultural settlements transformed into towns, urban joint type, developmental, limit the development of type, move disposable; Using the same method, the analysis results Lianyungang municipal districts of rural residential expansion constraints, and its restriction level to be pided, as Ⅰ ~ Ⅴ grade level district area. By comparing the priority and restriction levels, combined with the specific characteristics of the study area, the district of suitability high and low limiting should has the priority of development. Come to the spatial distribution of rural residential area of Lianyungang Municipality optimization.
