摘　　要：在城市内建设CNG汽车加气站成本高 ,合理布局CNG汽车加气站至关重要。结合技术经济学和交通系统分析的观点 ,探讨了公交车和出租车不同的加气行为 ,提出了CNG汽车加气选站时应遵循的 5项原则或假设 ,并根据最短路径理论建立了加气站和车站车源分配模型。通过对加气站车辆来源及售气情况的计算 ,得到加气站负荷率、投资回收期、加气行驶里程等 3类评价指标 ,对加气站布点选址与整体经济性进行了评价分析。编制了城市CNG汽车加气站布点计算机辅助选址评价软件 ,对城市新增加气站布点的合理性进行了预测检验 ,能满足用户对加气站的时空分布要求 ,为拟建城市加气站布点规划提供了参考。As the high cost of building a CNG filling station, the reasonable layout of CNG filling stations should be paid great attention. The article discusses the different CNG filling action of busses and taxies with the points of view of technical economy and communication system analysis, proposes 5 principles(or assumes) which should be followed when choosing the location to build a CNG filling station. According to the shortest distance theory, the distribution model of vehicles to CNG stations is set up. With calculating the number of vehicles to the stations and the profit of CNG selling, the 3 evaluation indexes i.e. the station load factor, the investment reclaiming period, and the distance of each filling can be obtained. The comprehensive economy evaluation is conducted for CNG filling station distribution. The computer-aided location choosing software is developed for urban CNG filling station layout. Based on the existing CNG stations, the reasonability of the locations of additional CNG stations is investigated to meet the users′ requirements. The article provides the reference to make the program of CNG station distribution.
