Abstract: Based on the classification of rural urbanization，the index systems for evaluating the development of highway and rural urbanization have been put forward. The methods for adaptability evaluation were established and the adaptablility index were used to evaluate their adaptabilities of Highway transportation and rural urbanization respectively. These methods were experimentally tested on two cities of Xi’an and Hanzhong in 2006. Conclusions suggests these methods are practically and reliably good，and the evaluation index is reasonably selected. Some proposals for improvement and measures were presented based on the evaluation results in order to provide the theoretical basis for enforcing the highway transportation and coordinating region society development thus to realize the sustainable development.

Key words: highway transportation, rural urbanization, adaptability index, cluster analysis

摘要： 在对农村城镇化进行分类的基础上，提出了公路交通和农村城镇化发展水平评价指标体系，建立了适应性评 价方法，并用适应性指数对两者进行适应性评价。然后以2006年西安、汉中为例对评价方法进行了验证，结论表 明:评价方法实用性和可靠性较好，评价指标选取也较为合理。在评价结果的基础上，提出改进建议和措施，为进 一步加强公路交通与区域社会协调发展提供理论依据，以实现可持续发展。
