| 摘 要： | 农村居民点作为乡村区域空间人口集聚形态的一种表现,是构成乡村聚落景观的一个重要部分,对其特征的分析研究对于推动城乡一体化建设和美丽乡村建设等政策的理论研究和实践开展和促进农村土地节约集约利用有重要意义。运用Ripley's K函数和ArcGIS 10.2中的核密度法来研究广东省揭阳市农村居民点的空间分布特征,建立河流和道路的缓冲区,从景观生态学的角度进一步分析影响居民点空间格局分布的因素,得出以下结论:(1)揭阳市农村居民点的空间分布格局属于集聚分布。(2)60%以上的农村居民点集中分布在由榕江、龙江和练江三大水系构成的河网体系周边。(3)农村居民点主要集聚在普宁、榕城、揭东、蓝城和空港经济区的县区范围。

| Abstract: | Rural settlements,as a manifestation of spatial population agglomeration in rural areas,are an important part of rural settlement landscape.Ripley's K function and the nuclear density method in ArcGIS 10.2 were used to study the spatial distribution characteristics of rural residential areas in Jieyang city,Guangdong Province,to establish buffer zones of rivers and roads,and to further analyze the influencing factors affecting the spatial pattern distribution of residential areas from the perspective of landscape ecology.Conclusions are as follows:(1)spatial distribution pattern of rural residential areas in Jieyang city belongs to agglomeration distribution.(2)More than 60%of rural residential areas are concentrated in the surrounding areas of the river network system consisting of the Rongjiang,Longjiang and Lianjiang rivers.(3)Rural residential areas are mainly concentrated in the counties of Puning,Rongcheng,Jiedong,Lancheng and Konggang Economic Zone. |
