摘　　要：以广州市已公布的4批美丽乡村建设试点数据为基础,通过最邻近指数、基于Riple’s函数的多距离空间聚类分析、核密度分析和叠置分析等方法,探讨了广州市美丽乡村的发展现状、空间分布格局及其影响因素。结果表明:1)自2013年起,广州市美丽乡村数量逐年递增且增长率呈现上升趋势;2)广州市美丽乡村空间分布呈明显的集聚型分布;3) Ripley’s函数分析表明美丽乡村要素点空间分布格局随距离变化略有不同,在0.14 km处集聚强度达到最大;4)核密度分析显示美丽乡村高密度区域主要分布在广州南部和西北部,包括番禺-南沙1个热点主核心区和从化、花都-白云2个热点副核心区,密度分布呈现多核心不均衡特点;5)乡村的地形水文、人文历史、交通区位和政策规划为美丽乡村空间分布的主要影响因素,其中,政策规划因素对"美丽乡村群"空间格局的形成起决定性影响。空间分布特征总体反映出广州市美丽乡村规划建设初见成效,并逐步形成以热点核心区为基础的"美丽乡村群"。最后,在乡村选点、空间优化、价值提升以及乡村治理等方面提出若干建议。At present,along with rapid urban-rural transformation,rural development faces a new round of challenges.Under the progressive drive of urban-rural integration development,new countryside construction,and the rural revitalization strategy,rural development has been gradually receiving attention.Since 2013,many nationwide rural construction practice explorations have been carried out.Among them,local practices represented by beautiful village construction have achieved staged results.In this context,based on four batches of 160 village construction pilots published by Guangzhou from 2013 to 2016,the research attempts to explore spatial differentiation characteristics of the beautiful village in Guangzhou and its influencing factors using GIS spatial analysis methods such as the nearest neighbor index,multi-distance spatial clustering analysis based on Ripley's function,kernel density analysis,and overlay analysis.Based on a geospatial perspective,this study attempts to provide a phased assessment of the current spatial distribution of beautiful village,to expand the spatial dimension of this kind of village and"village cluster"study.First,since 2013,the number of beautiful village in Guangzhou has increased year by year and the growth rate is on the rise.At the same time,their spatial distribution presents obvious concentrated characteristics.Nuclear density analysis shows that high-density areas of these villages are mainly distributed in the south and northwest of Guangzhou,including one hotspot main core area of Panyu-Nansha and two hotspots sub-core areas of Conghua and Huadu-Baiyun.The density distribution shows a multi-core imbalance.Second,the main factors affecting the spatial distribution of these villages include topography,hydrology,human population,history,transportation,location,policy,and planning.Among them,topography and hydrology constitute the basic motivation for rural development;deep historical and cultural resources are the spiritual driving force to support the continuous development of rura
