山区绿道建设的理论与实践

Theory and Practice of Greenway Construction at Mountainous Areas

从研究绿道及山区绿道的概念入手,探讨了山区绿道改善自然环境,营造安全稳定的道路环境;重构生态系统,恢复生态群落;丰富景观层次,形成具有标志性景观风貌的功能。选取安徽省响水涧抽水蓄能电站1#公路植被恢复概念设计方案作为实际案例,分析了项目概况以及山区绿道思想在该项目设计中的体现,阐述了其融合道路功能的需要、绿道功能的发挥以及人文内涵的设计理念,进而详细从风化严重的垂直边坡模式段、风化严重的陡坡模式段、阶梯型陡坡模式段探讨了各模式段的设计方法,并分别分析了作为道路景观节点的回头弯、观景平台的景观设计,重点讨论了山区绿道建设在满足安全原则及生态恢复原则的基础上注入景观内涵的核心设计思想,以期为当前道路绿化建设提供一些有意义的借鉴。

Starting from the concept of greenway and greenway at mountainous areas,the paper had discussed functions of greenway at mountainous areas.It was considered that greenway could ameliorate natural environment and create safe and stable road environment;reconstruct ecological system and recover ecological community;enrich landscape level and form symbolic landscape appearance.By taking Road 1# of pumped storage power station in Xiangshuijian of Anhui Province for example,it had analyzed the general situation of the project and embodiment of mountainous greenway in this project design;illustrated that it had integrated the need of road function,display of greenway function and design concept of humanity connotation;further discussed design methods for each mode section including vertical side slope with serious weathering,abrupt slope with serious weathering and laddered abrupt slope in detail.It had analyzed landscape design of turning section as note and observation deck respectively,preferentially discussed the core designing concept that landscape connotation should be instilled into greenway construction at mountainous areas based on the security and ecological recovery principle,so as to provide some significant reference for current road greening construction.
