考虑负效应的河谷型城市客运站选址研究

Study on Site Selection of Passenger Station in the Valley-City Based on ANP

河谷型城市由于受地形等因素的强烈限制,使城市发展随地形而布局。因此,其客运站的选址有别于平原城市。阐述了客运站布局和选址的原则,将ANP方法引入河谷型城市客运站的选址,结合河谷型城市的特点,给出了河谷型城市客运站选址的决策指标体系,并在此基础上建立了相应的客运站选址ANP模型,将选址过程涉及到的大量不确定的、模糊性、随机性因素及因素间的相互正负效应影响与依赖关系,利用ANP方法进行合理分析与处理。通过对兰州市客运站选址方案的实例分析,证明了所建ANP模型的正确性及ANP方法的实用性,对河谷型城市客运站的选址决策工作具有重要的指导意义。

The valley-city as a result of terrain limit causes the urban development layout along with the terrain. Therefore, the site selection of passenger station in the valley-city is different from the plain-city. The article elaborates the principles of the station layout and site selection, introduces the ANP method to the site selection of passenger station in the valley-cit- y. And based on the characteristics of the valley-city, proposes the decision-making index system for the site selection of passenger station in the valley-city, hence establishes the ANP model for the site selection of passenger station in the valleycity. The ANP method is used to analyze and process the massive indefinite, fuzziness, random factors as well as the factors for mutual influence and dependence in the process of site selection. Through the case analysis of site selection of passenger station in Lanzhou, it has proven the accuracy of the ANP model and the usability of ANP method, which is of sigifican to the decision-making work of the site selection of passenger station in the valley-city.
