摘要
以徐州地区SPOT与TM融合遥感影像及1:50 000电子地形图为主要数据源,通过人机交互解译,获得研究区的乡村聚落图斑、水系、道路、地形等空间信息.借助ArcGIS软件的空间分析模块为主要技术手段,对徐州地区乡村聚落的空间分布进行了定量化分析.结果表明:研究区绝大多数乡村聚落在局部空间上聚集;聚落沿水系、道路分布特征明显,距之越远,聚落数目越少;绝大多数聚落分布在50 m以下地势平坦地区,在大于50 m的低山丘陵地区分布较少.
In this article,taking Xuzhou fused image of SPOT and TM and electric map on the scale of 1∶50 000 as the major data sources,spatial information about rural settlement patches,water system and terrain is picked up by human-machine interactive interpreting.By means of ArcGIS spatial analysis technique,a quantitative analysis on spatial distribution of the rural settlements in Xuzhou is made.The result shows that major rural settlements are centralized in certain space;most settlements have favorable status of water system and traffic,the number of settlements decreases gradually as the distance away from them is farther;most settlements locate in the flat terrain below 50 m.
