After the in - depth study and compare of the main urban developmental modes , the paper puts forward the concep of the urban eco - transportation that the ideal urban development al mode fits into the demands of eco - city . this ideal urban transportational mode is based on the traffic enviromental carrying capacity ( tecc ) . then the theoretics frame of the urban eco - transportation planning is formed . during the process of urban eco - transportation planning , the tecc can be unproved by confirming the rational traffic structure and exploiting the urban land use model oriented by the rational traffic structure . besides , on the basis of the analysis of the eco - transportation planning phase brings forward the calculation content resent phase and the measure models of the tecc and applies these models to the practical calculations of the tecc of xi ' an city 本文在深入研究城市发展的主要模式后，提出适应城市发展的理想模式? ?生态城市要求的城市生态交通系统的概念，在交通环境承载力的基础上，构架了城市生态交通规划的理论框架。在城市交通规划中，可以通过确定合理的交通结构和开发以此为导向的土地利用模式，来提高tecc的限值。此外，本文还研究分析城市交通规划的阶段性，提出近阶段城市交通环境承载力的计算内容以及计量模型，并将这些模型应用在西安市城市交通环境承载力的计算过程中，得到较理想的结果。
