摘要
地理国情监测是我国测绘和地理信息发展的重大战略之一。其中地理国情监测单元网格划分是进行统计分析得到地理国情监测成果的基础。针对城市若以区为统计单位,统计单元网格过大,而以社区为单位,社区界线在图上位置不是很明确。提出在行政区划界线(区界)的基础上,采用道路网、河流、湖泊等构建网格,探讨采用渐进式的综合方法对网格进行聚合,得到城市统计单元网格。试验证明,该方法是进行城市统计单元网格的有效方法。
Geographic national conditions monitoring is one of the major strategic of mapping and geographic informatiou development in China.The generation of unit grid of geographic national conditions monitoring is the base work,which carried out a statistical analysis to get the geographic national conditions monitoring results.At the present,if zane boundary is adopted as the statistical unit,the grid is too large,or community boundary is adopted as the statistical unit,which location on the map is not very clear.It is proposed that on the basis of the administrative boundaries (zone boundary),the road network,rivers,lakes and other building grid were adopted to construct the grid,using incremental comprehensive methods to aggregate grid was discussed,the statistical unit grid of city was obtained.The experiment proved that this method can be used as urban statistical unit grid partition method.
