粤港澳大湾区三大港口集装箱货流的空间分布

Spatial Distribution of Container Cargo Flow in Guangdong-Hong Kong-Macao Greater Bay Area

以集装箱班轮航线为基础,构建以港口为节点、港口间的运力为边权重的有向加权海运网络,并从中抽取出与广州港、深圳港以及香港港有联系的港口节点和边.在此基础上,分别从出口货流和进口货流两个角度对广州港、深圳港以及香港港的集装箱货流在全球17个海运区域的空间分布情况进行对比,并就出口货流和进口货流在上述三个港口之间的集聚程度进行了分析.结果表明:(1)无论是在进口货流还是出口货流方面,与香港港建立联系的海运区域数量都是最多的,香港港的港口通达性最好;(2)深圳港的货流总量高于香港港和广州港;(3)进口货流主要集中在香港港,出口货流主要集中在深圳港;(4)东非、南部非洲、南美东岸和西非区域的进口货流呈现高度集聚分布的特点.

Taking ports as knots and connection between them as sides,this paper constructs a directed and weighted shipping network and extracts the portion relevant to port of Guangzhou,Shenzhen and Hong Kong from the whole network.Then,this paper compares the spatial distribution and analyze the concentration of container cargo flow of the above mentioned ports in global17shipping areas from outward and inward cargo flow respectively.The results show that port of Hong Kong has the best accessibility in both outward and inward cargo flow since Hong Kong contacts with maximum shipping area.However,the total flow capacity of Shenzhen is higher than Hong Kong and Guangzhou.In addition,the inward cargo flow mainly concentrates in port of Hong Kong while the outward cargo flow mainly concentrates in port of Shenzhen.Besides,the inward cargo flow of East Africa,Southern Africa,South America East Coast as well as West Africa is highly concentrated.
