北京市高速公路绿地植物景观设计探讨——以京石二通道(北京段)高速公路为例

Discussion on the Plant Landscape Design in Beijing Expressway Green Space——A Case Study on Beijing- Shijiazhuang( Beijing Section) Expressway

结合京石二通道(北京段)高速公路绿地的植物景观设计实践,提出:北京市高速公路绿地植物景观设计应满足"安全、舒适、实用、美观"的要求,以提供良好的车行环境、生态恢复和经济节约为目标。从宏观到微观进行设计:首先确定植物景观风格,其次根据适地适树的原则确定植物选择标准,再次采用以安全为前提,统筹考虑安全、生态、景观和管理等因素的综合设计手法,最后结合绿地特点选择和配置植物。

Combined with the plant landscape design in Beijing -Shijiazhuang （Beijing section） express- way green space, the target of expressway plant landscape design in Beijing is proposed by meeting the requirements of creating safe, comfortable, practical and beautiful environment, providing a favorable driving condition, restoring ecological environment and reducing costs. It should be designed from macro to micro： first deciding the landscape style, followed by determining plant selection criteria based on the principle of planting native and suitable trees, once again taking the safety as the prerequisite, and con- sidering safety, ecology, landscape and management factor, finally, choosing and arranging plants ac- cording to the characteristics of green space.
