山地城市拥有大量的坡地、堡坎、崖壁，在拓展公共立体绿化空间应用方面具有潜力，形成具有山地景观特点的立体绿化形式。以山城重庆为例，依据主城区坡地、堡坎、崖壁绿化美化的建设实施，归纳出山体生态屏障防护型陡坡绿化、江河生态护岸型陡坡绿化、道路沿线生态廊道型陡坡绿化、桥头立交节点型陡坡绿化、堡坎隧道口型陡坡绿化五类公共立体绿化。通过实地走访和典型案例评析，提炼出五类公共立体绿化的应用场景、设计模式、植物配置建议及其主要附加效益，总结重庆公共立体绿化的建设模式。

Mountainous cities have a large number of slopes, retaining walls and cliffs, which have the potential to expand the application of public three-dimensional greening space and form three-dimensional greening forms with the characteristics of mountain landscape. Taking the mountain city of Chongqing as an example, based on the construction and implementation of afforestation and beautification of slopes, retaining walls and cliffs in main urban area, five types of public three-dimensional greening are summarized, including steep slope greening for mountain ecological barrier protection, steep slope greening for river ecological bank protection, steep slope greening for ecological corridor along the road, steep slope greening for bridge interchange junction and steep slope greening for retaining wall and tunnel entrance. Through field visits and analysis of typical cases, the application scenarios, design modes, plant configuration suggestions and main additional benefits of five types of public three-dimensional greening were extracted, and the construction modes of Chongqing public three-dimensional greening were summarized.
