基于GIS的聊城市公路网络服务分析

城市公路网络服务与供给和需求密切相关,衡量区域的公路网络服务水平不能单纯从公路网密度出发,需要将供给与需求相结合进行分析。文章以GIS为基础平台,从网络服务供给与需求的相互协调关系出发,通过定量与定性相结合的方法,采用模糊聚类方法以聊城市8县市为样本分区,对公路网络服务水平进行分析评价,结果为:以相似系数在0.9以上为标准,把聊城市8个样本分为高、较高、中等、较低4个类型区,东阿、高唐为综合服务水平高类型;茌平为综合服务水平较高类型;阳谷为综合服务水平中等类型;东昌府、冠县、莘县、临清为综合服务水平较低类型。

Analysis on Service Level of Road Network of Liaocheng City Based on GIS

The service level of road network of an area is closed related to its status of demand and supply.It is necessary to consider road density and status of demand and supply together when we evaluate the service level of road network.By the combination of qualitative and quantitative analyses,applying the method of fuzzy-clustering and considering the status of demand and supply and coordination of road network,this paper assorts the 8 examples of Liaocheng city to 4 types based on GIS platform.Gaotang county and Dong'e county belong to high level type,Chiping county belongs to second high level type,Yanggu county belongs to middle level type,and Dongchang county,Guan county,Xin county and Linqing county belong to low level type.
