交通运输体现了城市之间的经济联系,是研究区域经济联系的重要依据。通过对省域公路客运、全国铁路和全国航空客运班期与距离关系的实证研究,深人探讨我国客运交通联系的距离衰减规律特征,得到三种客运方式的适宜营运距离、最佳营运里程和平均营运里程以及距离衰减规律的曲线估计模型,并对距离衰减规律的多样性特征进行了评述。
Traffic embodies the economic contacts among cities, and becomes importance when we research the economic contacts. Through study on passenger transport schedule about provincial highway, domestic railway and air, this article discusses their characters with passenger traffic contacts spatial attenuating tendency, obtains their feasible, optimal and average working distance, gives out the curve estimate model by the way of statistic analyze, In the end, this thesis remarks on the variety characters about spatial attenuating tendency.
