中文摘要：
以“绿色交通”为规划理念和区域发展为实践目标，探讨基于GIS的交通网络空间结构优化系统。在对交通问题进行结构分类后。构建载流对比分析模型，对各交通类型进行评估，测算区域综合承载能力。以河南省为研究区域，进行交通载流对比分析，评价单类交通类型的载流能力；根据区域的主导因素，将区域交通网络问题划分为3类问题域：经济过快型、建设不足型和分流不畅型，并针对性地提出3类网络结构优化方案：中心辐射、均匀分散和中转分流。借鉴双曲线交通结构，对核心问题域（郑洛焦济区）进行优化设计，为交通决策提供信息支持。
英文摘要：
Whether the transportation network structure is reasonable or no plays a vital role to regional sustainable development and its order- revolution. Based on the spirit of＇ green transportation＇, a system research of the optimization of regional traffic networks struc- ture is presented.After giving an analytic hierarchy process to the transportion,a flow- carrying contrast analytical mode and its indicator system are constructed. Taking the use of GIS tool, in order to evaluate regional traffic network structure, the type of solving plan is also presented. Taking the region of Henan Province as a study unit,three kinds of question regions,Classified by the leadership factor, are displayed. Three kinds of network structure optimization methodts are proposed pointedly. And based on the idea of a quotable mode called hyperbolic traffic structure, the oore question in this area is optimized in order to provide some useful information for the decision-making of transportation.
