摘　　要：川道型城市分布于丘陵沟壑之内,其城市轨道交通网络不可能像平原型城市那样以"面"形向四周扩展布局。通过对川道型城市的区域特征分析,总结出居民出行总体呈现"横向聚集、轴向交流"的特征,通过"线"形沿川道主轴布线,以川道断面客流测试轨道交通线路数量,根据组团连接关系拆分组合线路,形成川道型城市的概念线网,最后以西宁市轨道交通概念线网的构建作为示例,为今后川道型城市轨道交通线网布局提供借鉴。Valley cities are mostly located in hilly or gully areas where urban railway construction is not likely to be extended as in the plain cities. Through the analysis of the regional characteristics of the valley cities, the ＂lateral aggregation and axial flow＂ characteristics of the residents＇ travel are summarized in this paper. With the line - shaped layout along the valley lands, the number of the rail transit routes was calculated using the sectional passenger flows. The line combination was split according to the group connection, and the concept network of valley cities was developed. In the end, the construction of Xining rail transit network was demonstrated, which played a directive role in the distribution of urban rail transit network in valley cities.
