宁夏镇域交通优势度评价研究

Evaluation Research on Township Transportation Convenience Degree in Ningxia

根据《省级主体功能区域划分技术规程》中关于交通优势度的计算流程和技术方法,以交通网络密度、交通干线影响度和区位优势度为指标,通过ArcGIS和SPSS等,以宁夏198个城镇为研究对象,对交通优势度进行测算,得到宁夏镇域交通优势度的分布特征,并对其进行聚类分析.结果表明,宁夏镇域交通优势度的地域空间分布不均,空间差异明显,具有北高南低的区域分异特点.交通优势度比较高的地区主要集中在北部的石嘴山市和银川市及其附近县区,中部的吴忠市和中卫市交通优势度次之,南部的固原市交通优势度比较差.加强交通优势度低值区的交通基础设施建设,完善高值区的立体化交通网络,加强各县域与周边省辖市的经济联系,从而提高交通优势度,将为宁夏区域发展提供一定的支撑和保障.

With the calculation flow and technique regarding traffic advantage in Technology Regulation of Major Function Zoning on the Provincial Level,taking traffic network density,traffic artery influence degree,and regional advantage as indicators,with ArcGIS and SPSS,the article calculates the traffic advantage degree by taking 198 cities and towns as the researching objects to obtain the distribution characteristics of Ningxia’s township traffic advantage and makes clustering analysis.The result shows that,the distribution of regional space for township transportation advantage in Ningxia is uneven with obvious spatial difference and the regional differentiation characteristic of high in north and low in south.The region with higher transportation convenience is mostly located in Shizuishan and Yinchuan and the adjacent counties in north of Ningxia,Wuzhong and Zhongwei in middle part of Ningxia follow,and Guyuan in south of Ningxia is lower.It can provide a certain support and protection for the regional development of Ningxia to strengthen transportation infrastructure construction in low degree of transportation convenience,perfect three dimensional transportation network in higher traffic advantage,strengthen the economic connection between counties and surrounding provincially administered municipalities,and enhance the traffic advantage.
