摘要
我国属于多山的国家，尤其对于我国南方及中西部省份，城镇发展形态多为沿河流及峡谷地带展开，河谷型城市更加普遍，研究河谷型城市的道路交通改善策略，具有十分重大的意义，河谷型城市由于受到山脉的限制和河流的分割，与同等规模的平原城市相比，交通矛盾更为突出。本文以湖南省石门县为例，通过分析河谷型小城镇的道路交通特征及其影响因素，着重从宏观、中观、微观三个层面有针对性地提出中部河谷型小城镇道路交通在过境交通和过河交通等方面的策略建议：1）宏观通过区域交通综合规划，优化对外交通和过境交通；2）中观通过妥善处理内部交通，建立完善的内部交通体系；3）微观通过重视交通节点设计，减少交通薄弱环节等，以此为中部地区河谷型小城镇道路交通规划提供参考。
Because of the topographical condition, many cities in Southern and Central China are around the valleys. It is important to improve the road traffic in those cities. Taking Shimen County of Hunan Province as an example, this paper proposes three strategies for the road traffic improvement in valley cities： 1） On a macro scale, make regional transportation planning to improve external and transit traffic; 2） On a medium scale, set up a perfect internal traffic system; 3） On a micro scale, focus on the designs of traffic nodes and reduce the weak links. It is hoped to shed some lights on the future planning of valley city traffic.
