【摘要】：客货流地理是交通地理学研究的传统重要领域。本文利用位序—规模分布理论,对1980-2010年珠江三角洲客货运量等级规模结构分布特征及其变化进行研究。结果表明:客货运量规模的q值均大于1,符合位序—规模分布特征,但客运规模分布更显著。客运量q值先减小后增大,呈现出非均衡—相对均衡—非均衡演变特征;货运量q值逐渐降低,呈现出非均衡—相对均衡演变特征。在空间格局方面,客运空间格局呈现出由初期以广州为单中心向心型客运联系向穗莞深多中心客运联系转变;珠三角产业结构趋同性及以广州为中心的放射状交通网络结构,使得货运空间格局呈现出长期以广州为核心单核主导特征,主要表现为递接性联系特征。
[Abstract]:The geography of passenger and freight flow is a traditional important field in the study of traffic geography. In this paper, the characteristics and changes of the scale and scale of passenger and freight transport in the Pearl River Delta in the past 1980-2010 years are studied by using the theory of position order - scale distribution. The results show that the Q value of the passenger and freight volume is more than 1, which is in line with the sequence - scale distribution characteristics, but the passenger transport scale is more significant. The Q value of passenger traffic first decreases and then increases, showing a characteristic of disequilibrium, relative equilibrium and disequilibrium. The Q value of freight volume decreases gradually, showing a characteristic of disequilibrium relative equilibrium. In spatial pattern, the spatial distribution patterns of the passenger from the initial stage to Guangzhou as the single center to contact the Guangzhou Dongguan Shenzhen passenger type transformation center passenger contact; the convergence of industrial structure and the Pearl River Delta with Guangzhou as the center of the radial structure of the traffic network, the freight space pattern showing long-term in Guangzhou as the core of single core dominance the characteristics, mainly for the transfer of contact characteristics.
