Abstract: 城市交通与土地利用系统(Urban Transportation and Land Use System,简称UT-LU系统)是一个开放的、复杂的、非平衡的系统.针对现状中缺乏对UTLU系统内在演化机理的研究,本文以北京市为例,分别利用混沌理论和分形理论从时间序和空间序的角度揭示UTLU系统自组织演化的图景和结构复杂性.首先,利用小数据量计算法对北京市UTLU系统协同度的时间序列进行分析,确定最大Lyapunov指数,判断UTLU系统是否存在混沌现象,并结合混沌系统的特性进一步揭示系统演化图景;其次,分别从城市交通系统和土地利用系统中,选取适当的规模对象,利用位序-规模分形模型对北京市的UTLU系统自组织演化结构进行评定.
