空间扩散影响因素的研究是宗教地理研究的重要内容之一,而神职人员宣教地的窄间分布则可以间接地反映宗教在空间上的扩散情况。通过对广东不同历史阶段基督教宣教地的空间分布形态的分析,发现宣教地的分布与广东交通的发展关系密切。在清末以前水运交通占主导地位时期,宣教地主要分布在沿河海各港口,且因水运交通流向的改变而变化:19、20世纪之交,由于交通技术的进步,尤其是铁路的出现和轮船航运的兴起,一些重要的铁路枢纽和水铁转运节点相继成为宣教地。总体来看,宣教地的空间扩散明显带有点轴状的迁移扩散和以交通重要性来划分的等级扩散特征。这种扩散是交通综合影响机制作用的结果,影响因素包括与聚落的连通性、交通的便捷性、目的地的可进入性、距离衰减性以及交通现代性的影响等多方面。
The spatial distribution of Missionary Residential Centers (MRCs) in Guangdong can show indirectly its close relationship with transportation in different time. Before 1880s', as water transportation was predominant, MRCs were laid out mainly at the river ports and sea ports, and moved with the change of water traffic flow. At the turn of century, with the appearance of railways and steamboats, some important railway stations and transfer spots between water carriage and railway had become MRCs, and the Pearl River Delta and Chaozhou-Shantou zone were the two largest central areas of MRCs. In general, the spatial diffusion of MRCs had obvious characteristics of spot-axis migration and their rank depended on the importance of transportation stations. The diffusion of MRCs was influenced by transportation. The influence factors included the connectivity of residental areas, transportation convenience degree, accessibility to destination, distance declination, as well as the influence of modern transportation.
