基于全生命周期的铁路客运站绿色等级评价

铁路客运站作为城市交通系统的重要节点,在城市绿色交通系统建设中处于重要地位。对客运站绿色等级进行科学评价是指导绿色客运站规划、建设的基础。根据绿色建筑定义,结合铁路客运站特点,提出绿色客运站及客运站绿色等级的概念;基于全生命周期原则,构建规划设计、建设以及运营各阶段客运站绿色等级评价指标体系;以可拓学理论为基础建立客运站绿色等级物元评价模型,运用G1法确定各指标权重。最后对H客运站进行绿色等级评价,利用MATLAB实现评价过程中的矩阵运算。结果表明:物元模型适用于客运站绿色等级评价。

Evaluating the Green-grade of Railway Passenger Stations Based on Whole Lifecycle

As important nodes of the urban traffic system,railway passenger stations play a significant role in constructing the green traffic system in urban areas.Combining the characteristics of railway passenger stations and the definition of green architectures,we put forward the concepts of the green railway passenger station and its green grade,and set up the evaluation index system of passenger stations on the basis of the whole lifecycle including planning,construction and operation stages.Using the extenics theory,the matter-elements model to evaluate the green-grade of passenger stations was established and the weights of indices were calculated by use of the G1 method.The green grade of Station H was evaluated with the proposed method,and MATLAB was employed to carry out matrix operations.The results show that the matter-element model has vast prospect in evaluating the green-grade of railway passenger stations.
