| 摘 要： | 社会数据的空间化是现代地图制图学研究的主要内容之一。本文提出了区域统计指标的概念并将其分为区域平均指标与区域总量指标两种类型,成功地将网格单元面积权重内插(GCAW I)法引入到区域统计指标的空间化工作中,应用GCAW I法实现了新沂市耕地标准亩指标的空间化表达,结果表明:运用GCAW I法进行区域统计指标的空间化不仅可以很好地避免传统方法的同一区域均匀分布、不同区域突变分布的缺点,而且经kriging插值后的地图很好地符合区域统计指标空间分布的特点,生成的3维可视化地图更加切合实际。

| Abstract: | Spatial data spatialization is one of the main research fields of modern cartography.This paper put forward the concept of regional statistical indices and divided it into regional mean indices and regional total indices.It applied the Grid Cells' Areal Weighting Interpolation(GCAWI) to spatialize the regional statistical indices and realized the spatialization of cultivated land indices in standard mu for Xinyi City.The results showed that using GCAWI method to spatialize the regional statistical indices not only can avoid the shortage of well-proportioned distribution in the same area and discrete distribution in different area,but also the map by Kriging interpolation can conform to the spatial distribution feature,and the 3D visualization map is more reasonable. |
