摘　　要：基于改进的耦合理论模型对高速公路与区域城市化进行协调度评价,并采用实例分析。研究结果表明:城市化发展远超出现有高速公路的承载能力和城市化所要求的高速公路应具有服务功能。这与现实状况相符,表明模型可信;并由此提出城市化背景下高速公路改建策略。Based on the improved coupling theory model for evaluating the coordination degree of highway and regional urbanization,a case study was performed.Results show that the development of urbanization is far beyond the bearing capacity and service function of freeway,and that freeway does not have service functions required by the urbanization.This is in agreement with the reality,which indicates that the model is reliable.Finally,the highway reconstruction strategy under the background of urbanization is put forward based on such a situation.
