摘要
引入移民适宜性因子来分析客家民系迁移过程中主体对环境的适应性,将客家聚落形成过程视为迁移与定居过程的统一。建立客家迁移地形和古交通通道数据库,构建基于栅格数据结构的空间可达性分析模型,分析客家民系迁移最优路径选择过程;并定量分析了客家聚落的定居适宜性。基于上述分析数据,通过基于离散事件的仿真模拟客家民系文化迁移扩散的时空分布特征。基于移民适宜性因子的客家民系迁移过程的仿真结果显示:客家民系迁移时空演进中的阶段性分布较为明显,赣南、闽西汀江流域、粤东北地区呈现出以赣州、长汀、梅州为中心的3个文化片区,客家民系文化层级、文化中心(客家首府)的分布与移民适宜性呈现相关性。
The paper introduces quantitative methods and a GIS platform into the Hakka migration research,which is usually analyzed qualitatively by social scientists.To interpret the hierarchical cultural diffusion of Hakka cultures,the article introduces adaptability for emigrant factors to analyze how Hakka people adapted to the environments and its temporal-spatial characteristics quantitatively through spatial analysis and discrete-event simulation.A GIS database of Hakka migration has been established with landforms and ancient road information.Subsequently,the optimal migration route was analyzed and modeled based on raster data.The simulation result indicates that the Hakka settlement is constituted by three culture area located in the overlapping region of Jiangxi(Gan),Fujian(Min),and Guangdong(Yue or Canton)province.Ganzhou,Changting and Meizhou are considered as the ' Capital' of the forementioned area.The analysis result also explains adaptability for emigrant factors correspond with the hierarchical cultural diffusion of Hakka cultures and the distribution of the so called Hakka Capital.
