摘要
城市轨道线网规划对优化城市社会、经济、生态环境,实现城市生态环境可持续发展有着至关重要的作用。文章通过熵值法与属性识别模型相结合,建立了基于熵权的属性识别模型,用该方法对城市轨道线网方案进行综合评价,并结合西安市城市轨道交通线网规划中的4个预选方案进行了评价,推选出最优方案。结果表明,该评价方法结果合理,决策科学,具有较好的应用前景。
The planning of urban rail transit network play an important role in the optimization of urban society,economy and ecological environment, and make the urban ecological environment sustainable development. By combine the entropy value theory and attribute recognition model together, attribute recognition model based on coefficient of entropy is set up and applied to evaluating urban rail transit network by the new method. This method was applied to Xi＇an urban rail transit network planning, the best one in four network plans was chosen. The result shows that this method has a better application prospect for it＇s simple calculation and science decision.
