摘要：为科学引导即将广泛开展的省域绿道网规划建设实践，探索了省域绿道网规划建设实施中可能遇到的关键问题。首先，针对省域绿道网建设周期长、规模大、资金需求多的特征，提出应优先选择条件良好的地区先行建设，而后再逐步推进。其次，针对绿道网规划中的难点问题，提出以追“绿”择“道”成“网”的整体选线方式，确保省域绿道的网络化与生态化；以借道、并道等绿道连接线形式和与机动车道平交或立交等技术手段保证绿道网贯通和使用安全；以无缝衔接实现绿道网与机动交通系统的平稳过渡，提高绿道网的可达性和使用效率；以省际、城际和跨界互连互通技术推进绿道网向更广泛区域扩张。最后提出，应建立省域绿道网可持续发展机制，并提出管理维护规范化、功能开发多元化、效益评估制度化的建议。

Abstract：To better guide the development of provincial greenway network, the author discusses several key issues in the construction and implementation process. Firstly, considering the long construction cycle, large project scale and huge development budget, the paper states that it is important to conduct a pilot project at a location with the best implementation conditions. And then expand the greenway network project to other areas. Secondly, aiming to solve the critical problems in greenway network planning, the paper proposes that the route selection should be based on "green", "route" first, and then to develop the "network" to make provisional roadway as ecological greenway; to ensure the connectivity and security by greenway connecting line formation including reversible lanes and merged lanes; to ensure the smooth transition of greenway network and motorized traffic lanes by seamless connection which can improve the accessibility and service efficiency; to expand the greenway network by provincial, intercity and transboundary communicational technique. Finally, the paper states that it is important to develop the sustainable provincial greenway network and suggests to have the standardized management system and multicultural functional benefit assessment system.
