摘　　要：在对可达性内涵进行评析的基础上,将其分析拓展到低碳生态城市三维空间模型研究中。借助既有研究成果,基于灰色系统GM(1,1)模型构建了低碳生态城市可达性分析的一般模型,用以对生态指数、低碳指数和幸福指数的可达性分析,并据此计算出发展度、持续度、协调度和有效发展度的预测值,形成对低碳生态城市的总体可达性分析。将该模型应用于天津城市发展可达性分析,证明该方法科学可行。Based on the analysis of the connotation of accessibility, the conception of accessibility was expanded and used into the research of the three-dimensional space model for a low-carbon eco-city. In virtue of the existing research, an accessibility analysis model of low-carbon eco-city was constructed using the model of gray system GM（1,1）. This model was used to analyze the accessibility of ecological index, low-carbon index and happiness index and calculate the predicable values for development degree,sustainability degree,coordination degree and virtual development degree. The general accessibility analysis of the low-carbon eco-city was established. This model was applied into the accessibility analysis of Tianjin development and proved to be scientific and feasibile.
