摘要:: 芒市至临沧区域属横断山脉南段，地广人稀，城镇零散，经济落后，地形、地质条件极为复杂。如何以区域铁路网规划为前置条件，选择工程安全可行、经济效益最佳的线路，是本项目的研究主要问题。本文借鉴临清铁路可行性研究结论，提出了区域铁路网北、中、南三大线路走向组合方案，从社会服务效率、工程安全可靠、铁路建设总规模等方面进行了综合比选，推荐采用南线组合方案。既符合区域铁路网规划的指导思想，又实现了区域铁路经济社会效益最佳的目标。研究中所秉持的"服务经济据点最多、工程风险最低、工程投资最少"区域铁路选线思想，可为类似贫困山区的铁路规划设计提供借鉴。

Abstract:: The Mangshi-Lincang Railway is in southern section of Hengduan Mountains, with vast land, sparse population, scattered towns, backward economy and extremely complex terrain and geological conditions. How to select a safe and feasible route with the best economic benefit based on current railway network planning is the main research issue of this project. Based on the conclusion of the feasibility study of Linshang-Qingshuihe Railway, this paper puts forwards the combination schemes respectively in north, middle and south directions of the regional railway network; through comprehensive comparison from the aspects of social service efficiency, engineering safety and reliability, and the total scale of railway construction, the combination scheme of the south line is recommended. It not only conforms to the guiding ideology of regional railway network planning, but also achieves the goal of the best economic and social benefits of regional railways. The regional railway route selection principle of "serving the most economic strongholds, the lowest project risk and the least project investment" upheld in the study can provide a reference for railway planning and design in similar poor mountainous areas.
