基于GIS技术的贵州省城市影响腹地划分

A GIS-based Approach for Urban Hinterland Research in Guizhou

利用GIS的网络通达性分析功能,根据胡佛模型,采用实际交通距离替代直线距离的方法,计算贵州省九个地级市的腹地范围。通过划分结果可知,贵阳腹地规模在全省具有绝对优势,是省内发展的龙头;遵义、六盘水、毕节、凯里、都匀、兴义、铜仁、安顺腹地规模依次递减。根据研究结果,提出巩固贵阳市省内发展的核心地位,建立三级城市经济影响区,走集约发展的道路。

The hinterland of the nine cities in Guizhou province is studied by using GIS and Huff Model. The results and conclusions are as follows： Guiyang hinterland dominates the region and accelerates the development of the province; the area of the hinterland of Zunyi, Liu Panshui, Bijie, Kaili, Duyun; Xingyi,Tongren and Anshun decline one by one. According to the results and conclusions, it is recommended to concrete the core role of Guiyang and build three levels urban economic zones.
