d维格子中的城乡人口迁移
Rural-urban migration in d-dimensional lattices
摘要:
采用基于主体的计算模型分析了农村人口向城市迁移的现象。代理商被放置在格子上,其尺寸从d=2到d=7不等。代理商在格中的本地化定义了他们的社会邻里(农村或城市),与他们的空间分布无关。通过分析表征迁移过程的主要参数的变化,研究了晶格维数的影响。动态显示强大的影响,甚至约一百万的网站,在更高的维度(d=6,7)。
英文摘要:
The rural-urban migration phenomenon is analyzed by using an agent-based computational model. Agents are placed on lattices which dimensions varying from d=2 up to d=7. The localization of the agents in the lattice define their social neighborhood (rural or urban) not being related to their spatial distribution. The effect of the dimension of lattice is studied by analyzing the variation of the main parameters that characterizes the migratory process. The dynamics displays strong effects even for around one million of sites, in higher dimensions (d=6, 7).
