摘　　要：基于GIS和景观格局指数对沿海区域农村居民点分布状况进行研究。以连云港市赣榆区为研究区,从天地图影像中提取居民点信息,以乡镇为单位,利用地理科学、景观生态学、主成分分析和聚类分析等理论方法,借助SPSS统计软件,对选取的16个景观格局指数进行降维处理,得到4个主成分;然后通过系统聚类分析把赣榆区全部乡镇分成6类进行分区研究。每类景观格局指数可表征该分区农村居民点的分布范围、分布的聚集离散度以及整体分布形态。研究成果对农村土地利用规划、农村公共文化服务建设、农村居民点整理、农村医疗教育等农村问题具有重要参考价值。Taking Ganyu District in Lianyungang as the study area, this paper extracted the rural settlements in townships from the Map World to study the rural settlements distribution in townships along the coast based on GIS and landscape indexes. The paper made use of the geographical science, landscape ecology, principal component analysis(PCA) and cluster analysis to draw four main components form the chosen 16 landscape indexes by SPSS statistical software. And then, the paper analyzed all the Ganyu District towns which were divided into six categories by hierarchical clustering partition research. Each type of landscape index can show the typical distribution of the rural settlements distribution, the aggregation of discrete distribution, as well as the overall distribution pattern. This research results can provide some important implications for the rural land use planning, the public cultural services in rural area, the rural settlements consolidation, the rural health care and education and so on.
