摘要
本文通过检索CNKI数据总库上有关元胞自动机的文章,提取这些文章的高频关键词,生成共词矩阵,然后在共词因子分析与聚类分析基础上对元胞自动机理论在土地学科领域研究结构、研究热点、存在问题进行可视化分析。目的在于综合阐述元胞自动机理论在土地学科领域的研究现状,同时提出CA理论与应用研究的一些建议,为从事CA理论与应用研究的学者提供一些信息参考。研究结果表明:元胞自动机是一个复杂的理论体系,这个理论体系中土地领域的研究尚且不是很成熟和完善,首先应当加强动态转换规则和寻找适合研究区参数值的研究,其次在CA的应用过程中应当充分结合多智能体的研究成果,以提高应用成果的客观性;在CA模拟方法上,应当加强CA与GIS的有效结合,以解决更多基于GIS数据的实际问题,同时更好地让CA模拟实用化。
This paper,based on papers regarding cellular automata from CNKI database,extracts the frequently used keywords to generate co-word matrix,makes a visual analysis on the structure,points and issues in land research according to co-word factor analysis and cluster analysis,and presents some suggestions for CA theory and application,providing references for scholars doing CA study.The results show that(1) cellular automata is a complicated theory system of which land research is not mature,which can be improved by dynamic convert rules and suitable parameters,and by integrating multi-intellect results during CA application;and(2) CA shall be fully combined with GIS in order to resolve problems of GIS and to enable CA simulation.
