摘　　要：针对目前行政边界的尺度选择存在不确定性,道路的选取过于依赖其原始的等级划分,融合人文要素的网格细分自动化程度较低等问题,提出一种基于地址模型的城市网格划分方法.首先在网格划分过程中引入地址模型,以地址模型中行政区划要素的层次划分确定行政区划要素选取;然后解析地址模型,处理面向划分主题的人文要素地址数据,抽取更契合划分主题的道路要素,实现一种以行政区划边界和道路为基础框架,贴合应用主题的城市网格划分方法;最后,以福州市鼓楼区兴趣点网格为例验证该方法.实验结果表明:在有效约束条件下,该方法能更有效地融合两类划分要素,并将人文要素信息融入道路选取中,可以实现结合人文要素的自动化网格细分,便于网格的更新.In view of the uncertainties in the current scale selection of administrative boundaries,the selection of roads relying too much on its original grade division,and the low degree of automation of grid subdivision integrating human elements,an urban grid division method based on the address model is proposed.This method firstly introduces the address model in the process of grid division,and determines the selection of administrative division elements based on the hierarchical division of administrative division elements in the address model.Then the address model is analyzed,address data of humanistic elements oriented to the theme division is processed,and road elements that are more suitable for the theme division are extracted,so as to realize a city grid division method based on the framework of administrative boundaries and roads,which fits the application theme of a city grid division method.Finally,taking the grid of points of interest in Gulou District,Fuzhou City as an example,the experimental results show that the proposed method can more effectively integrate the two types of classification elements under valid constraints,and integrate the information of human factors into the road selection,which can realize the automatic grid subdivision combining with human factors and facilitate the grid update.
