摘要: 提出了基于扩散生长的状态型CA模型、基于轴线生长的交通型CA模型和基于优势驱动的环境型CA模型等三种CA模型,设定了包围填充、扩散生长、交通延伸、交通连接、交通吸引、优势生长等6种转换规则。模拟结果表明,武汉市主城整体上呈现出“摊大饼”的发展态势,并且扩散到城市地区,近郊优势增长十分明显,导致了大规模的郊区化,呈现出城乡一体化的发展态势Abstract: This paper puts forward three CA models: expansion\|based state CA model, axis\|based traffic CA model and advantage\|based environment CA model, designs six conversion rules:surround filling,expansion growth,transportation extension,transportation conection,transportation atraction and advantage growth. The simulating results shows that the urban spatial growth is presenting the tendency of growing into an organic whole from urban to subur
