基于GIS的广东地名景观分析

为对广东地名景观进行定量分析,文章首先依据最新广东省地图集利用数理统计方法进行地名数量统计,在此基础上,利用GIS技术,建立广东地名元数据库(GEODATABASE),通过ARCGIS中的GEOPROCESSING、SPATCIAL STATISTICS TOOLBOX和ANALYSIS TOOLBOX等对数据属性要素进行分析、分区、分异和颜色色差处理,输出所需的直方专题地图和其他所需专题地图。其后得出,广东地名景观表现出岭南特有的地理环境特征和历史发展特征,在空间分布上具有不均衡性,通名和专名具有多样性,齐头地名分布的集中性和具有多族群性及方言性。文章还在统计的基础上,利用GIS技术进行分类和地理区划,将全省地名景观按类型分为四大区,即客家、福佬、壮语和粤语地名区,且各自在空间上表现出核心—边缘分布景观。
