中文摘要：

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.

英文摘要：

Urban Transportation and Land Use System （UTLU system） is open,complex and nonequilibrium.Since the study on evolution mechanism of UTLU system is limited,this paper takes Beijing as example,both chaos theory and fractal theory are employed to reveal the evolution prospect and structural complexity respectively.Firstly,small-data method is used to analyze the time series of synergy degree of UTLU system,and the largest Lyapunov exponent is calculated which is used for judging the chaos phenomenon of UTLU system.Then the feature of chaos system is utilized to reveal the evolution prospect in depth.Secondly,select proper scale objects from transportation system and land use system respectively,and then the RankSize rule is adopt to evaluate the evolution of UTLU system.
