摘　　要：主要对城市影响范围的划分方法进行研究.首先以点状地理实体对象为例,提出了地理对象影响域的概念;然后阐述了地理对象的影响域分析方法;接着在二维异质环境下应用该方法对河南省17个地市进行了影响域划分;并与GIS划分方法进行了对比.最后对该方法的特点和分析应用场景进行总结说明,讨论了存在的问题和需要进一步研究方向.The dividing method of urban impact scope is mainly studied.Firstly,the concept of im-pact scope of geographical object is proposed by taking point geographical object as examples, then the impact scope analysis method of geographical objects is expounded.After this,the meth-od is applied to divide the impact scope of 17 cities in Henan Province in two-dimensional hetero-geneous environment,and it is compared with GIS division method.Finally,the characteristics of this method are summarized and its application scenarios are described,and the problems of the method and the direction for further study are probed.
