定量分析城市各种交通方式的生态水平,可以为城市交通规划和设施建设提供参考依据.引入生态指数概念衡量各种交通方式的生态水平,借鉴各种交通方式在土地占用、能源消耗和环境污染指标方面较成熟的计算模型,选择恰当的标准化方法,将原始数据转化成生态指数定义中通用的数据格式进行计算分析.以大连市为例进行分析,得到私人小汽车、出租汽车、常规公交、快速公交、轨道交通、步行和自行车交通方式的生态指数分别为0.26,0.24,0.18,0.15,0.12,0.02和0.03,直观地反映了不同交通方式的生态化水平.%Quantitatively analyzing ecological level of the various travel modes in cities can provide a reference for urban transportation planning and infrastructure construction. To measure the ecological level of the various travel modes, this paper introduces the concept of ecological index. Then, the paper learns from the mature indicators formula and selects appropriate standard method of land use, energy consumption and environmental pollution, in order to draw raw data into common data form in ecological index definition. Therefore, the calculation for the eco-index defined style could be carried on. In case study of Dalian City, the ecological index of rail, private car, taxi, regular bus, bus rapid transit, walking and cycling is 0.12, 0.26, 0.24, 0.18, 0.15, 0.02 and 0.03, respectively. The quantified indicators for ecological index can directly reflect the ecological level of the different travel modes.
