关于西南路网骨架的思考

THINKING ABOUT STRUCTURAL FRAME OF RAILWAY NETWORKS IN SOUTHWEST CHINA

本文在分析我国当前西南既有铁路网概况的基础上，提出西南铁路网建设应遵循的基本原则。对建成西南铁路网骨架提出初步设想，主要着重阐述三个方面：（１）建成兰州－昆明大通道，加强西北与西南的联系；（２）修建泛亚铁路，打通国际通道；（３）修建进藏铁路，并提出几点建议。

Based on the analysis of recent situation of the existing railway networks in Southwest China,the basic principles which should be followed in construction of railway networks in Southwest China are proposed. The preliminary tentative plan concerned with establishing the structural frame for the railway networks in Southwest China has been proposed, and expounded emphatically in following three aspects: (1)constructing Lanzhou-Kunming extra-long railway passage to enhance the connection between Northwest China and South- west China, (2)constructing Pan-Asia Railway to open up the international railway passage,and (3)constructing the railways towards Xizang. Several suggestions are proposed also in this paper.
