摘　　要：现有道路网选取方法大多是在路化的基础上对道路网数据进行单一选取,很少顾及其与周围环境的空间关联。本文提出一种在居民地约束下进行道路网分区选取的方法,首先,根据居民地分出繁华区域、一般区域以及远郊区域;然后,根据道路网的拓扑结构进行分类,并提出一种分类选取的原则;最后,基于该原则分区分类进行道路网选取,得到综合后的道路网结果。试验表明,本文方法能够有效、合理地保持数据的空间分布特征和相对密度。Most of the existing selection methods of road networks feature a single selection of road network data on the basis of road channelization,rarely taking into account the spatial relationship between the road and the surrounding environment.This paper proposed a zoning method for selecting a road network under the constraints of residential areas.Firstly,the paper divided the bustling area,general area,and suburban area according to the residential area.Secondly,the paper conducted classification according to the topology structure of the road network and put forward a principle of selection by classification.Finally,based on this principle,the road network was selected by zoning,and the integrated road network results were obtained.The experiment shows that the method proposed in this paper can effectively and reasonably maintain the spatial distribution characteristics and relative density of the data.
