摘要
以吉林省域内聚落点为研究对象,ArcGis10.6为基本工具,在分析各类影响因素的前提下,采取平均最近邻指数、核密度计算、缓冲区分析等定性与定量结合的方法,研究总结松花江流域、辽河流域、鸭绿江流域、图们江流域及绥芬河流域内聚落分布特征与之各个聚落的特色.结果表明,聚落在空间分布上受地形地貌影响较大;分布形式上绝大多数地区呈凝聚型分布;在聚落空间上呈现“中聚集两边疏多散点”的分布格局;自然保护区与聚落点错落有致;不同聚落的特色各不相同,形成了吉林省独特的自然地理环境等特征.
Taking the settlements in Jilin province as the research object,and ArcGis10.6 as the basic tool,under the premise of analyzing various influencing factors,the qualitative and quantitative methods such as average nearest neighbor index,kernel density calculation,buffer analysis and so on are adopted to summarize the research.The distribution characteristics of settlements in the Songhua river,Liaohe,Yalu,Tumen and Suifen river basins and the characteristics of each settlement.The results show that the spatial distribution of settlements is greatly affected by topography.It is agglomerative distribution in the settlement space,there is a distribution pattern of“central aggregation on both sides and many scattered points”;nature reserves and settlements are scattered;the characteristics of different settlements are different,forming a unique natural geographical environment etc.feature in Jilin province.
