摘　　要：为分析区域人口对交通建设的影响,提出了一种基于对数函数的交通与人口相关性分析方法。利用交通网络密度、交通干线影响度、区位优势度构建衡量区域交通建设水平的交通优势度,利用人口密度表达区域的人口压力;采用对数函数对交通优势度与人口密度之间的函数关系进行拟合,在此基础上进行相关性分析。在四川省的实验结果表明区域交通与人口之间存在较强的相关性。In order to analyze the influence of regional population on traffic construction,a method of correlation analysis between transportation and population based on logarithmic function was proposed in the paper. Transport superiority which measures the regional traffic construction level was built by transport network density, influence degree of transport trunk line and transport superiority degree of location. Population density was employed to express the regional population pressure. The logarithmic function was used to fit the function relationship between the transport superiority and the population density, then correlation analysis was adopted. The experimental results in Sichuan province show that strong correlation exists between regional transportation and population.
