区域对外综合运输通道布局规划

立足于全方位对外开放格局下区域对外综合运输通道的布局研究，在节点重要度和交通区位联合布局法的基础上，对区域外部环境进行了补充分析，调整并优化了布局方案，克服了重要度联合交通区位布局法局限于区域内部分析的不足。以四川省出川综合运输通道布局为例，对四川省地级市及以上节点进行了重要度评价分析。利用区位重要度计算结果，结合外部环境分析，确定了较为合理的布局方案。

The layout planning of the external integrated transport corridor of one region

The layout of external integrated transport corridor of one region is studied based upon the all-around opening patterns. Based on the method of the importance of nodes and the combined traffic location layout, the analysis of the external environment of one region is complemented, the optimization of the layout scheme is adjusted, which can overcome the weakness of the method of the importance combining traffic location layout with the regional internal analysis. The method on the integrated transport corri- dor layout of Sichuan Province is used.An analysis of the importance evaluation of pre- fecture-level cities and the above node in Sichuan Province is carried out. The results of the location importance is obtained. The most reasonable layout scheme combining with the analysis of the external environment is determined.
