摘要基于GIS的网络分析功能，采用比值法、时间距离法和可达系数法三个可达性指标，本文详细分析了丰县地区各乡镇交通网络的通达情况。通过综合分析，可达性最好的是凤城镇、孙楼镇、常店镇、宋楼镇，其次是师寨镇、华山镇、大沙河镇、王沟镇，较差的是首羡镇、梁寨镇、范楼镇。丰县县域内各镇交通基础设施建设状况差异性较大，呈现出两极化倾向。本文研究成果将为更加有针对性地改善地区交通状况,促进乡镇地区经济发展提供参考。68940

Accessibility of the road transportation network based on GIS : A case study of township in Fengxian County 

Abstract

Based on GIS network analysis modle, choosing three main accessibility indices including the ratio index, the time distance index and the accessible coefficient index, this paper has analyzed the accessible situation of the road transportation network in each towns of Fengxian county in detail. Through a comprehensive analysis, Town Fengcheng, Town Sunlou, Town Changdian and Town Songlou have the best of accessibility, followed by Town Shizhai, Town Huashan , Town Da Shahe and Town Wanggou , poor is the town Shouxian, Town Liangzhai and Town Fanlou. The condition of transportation infrastructure within the Fengxian county has larger differences which shows a polarization trend. This paper will provide reference for more targeted to improve the traffic situation in the region, and for the promotion of the economic development of the township area.
