【摘要】 选择广东省揭东县龙尾镇的乡村聚落为实证研究对象,以2006、2016年揭东县龙尾镇的遥感数据和DEM为数据源,采用GIS空间分析方法定量分析2006-2016年该区域乡村聚落空间分布特点及演变因素。结果表明:龙尾镇乡村聚落趋向大中型聚落发展,人口和聚落密度较高,乡村聚落在空间分布上较为集中,空间扩展特征比较显著,但地区差异明显;乡村聚落斑块随高程和坡度均呈偏左正态分布且表现出明显的空间集聚态势,高程10~80m和坡度3~7°区域是乡村聚落的密集分布区;乡村聚落沿道路集聚趋向十分明显,沿主要道路形成组团式聚落斑块。地形等自然地理因素是揭东县龙尾镇乡村聚落空间格局形成与发展的基础,但经济发展、人口增长、交通区位、传统文化和宗族势力等人文地理因素是影响该区域乡村聚落空间演变的主要驱动力。更多还原

【Abstract】 The Longwei Town of Jiedong was chosen as a case to study the distribution characteristics and influencing factors on the rural settlements with DEM and remote sensing data of 2006and2016,and with GIS spatial analysis of 2006-2016.The results show that:the Longwei Town is dominated by large and medium-sized rural settlements,with population and settlement density being higher,the characteristics of spatial expansion being obvious,but regional difference settlements present a skew normal distribution along with the elevation and slope,for most settlements are located at the elevation of 10~80mand the slope of 3~7°.The trend of the distribution centralized along the roads and rivers is very clear,along the main road form colonies depended plaques.Terrain and other natural conditions are the foundation of the overall spatial distribution with the rural settlements of the Longwei Town,while some main geographical factors such as economic development,population growth,traffic location,traditional cultures and clan,influenced the evolution of spatial distribution of the rural settlements in the Longwei Town.更多还原
