在提倡低碳经济、建设生态高速、共建和谐社会的时代背景下,高速公路景观设计倡导与周边环境融合的共生一体化设计。通过共生一体化的景观设计,使得高速公路所形成的带状景观与沿途空间景观环境相协调、相融合、相渗透,将线状景观变成为二维面状景观、三维体状景观,使得景观与环境之间如“宿主”与“共生体”一般,实现“共生一体化”的目标。文中重点阐述了实现共生一体化设计的三个途径——乡土化设计、生态化设计和恢复性设计。 Under the background of promoting the low-carbon economy, building a high-speed ecological environment and building a harmonious society, the symbiotic integrated design of highway landscape design advocating integration with the surrounding environment. Through the symbiosis and integration of landscape design, the ribbon landscape formed by the expressway is coordinated with the landscape environment along the route, and the linear landscape is transformed into a two-dimensional planar landscape and a three-dimensional landscape so that Between the landscape and the environment, such as “host ” and “Symbiosis ” in general, to achieve “symbiotic integration ” goal. The article focuses on three ways to achieve symbiotic integration design - local design, ecological design and restoration design.
