结合工程实践和思考,提出分层次、分区域、分路段、分时间效果,按公路的核心功能和网络地位,以及区域自然生态环境现状和发展趋势,定性确定公路生态景观建设项目等级;按观赏、享受视点的移动速度和视点的位置,定性确定公路生态景观建设功能区单元等级;按公路生态景观的时间效果,定性确定公路生态景观建设时间效果等级;按内外视点,定性确定公路生态景观建设视觉单元等级,以指导公路生态景观建设,作为公路生态景观建设执行的“尺度”。
According to the engineering practice and thinking, this paper puts forward the hierarchical, sub-regional, sub-section and sub-time effects. According to the core functions and network status of the highway and the status quo and development trend of regional natural ecological environment, the grade of highway ecological landscape construction project is qualitatively determined. , Enjoy the moving speed of viewpoint and the position of viewpoint, and qualitatively determine the unit level of functional area of highway ecological landscape construction; determine the time effect grade of highway ecological landscape construction qualitatively according to the time effect of highway ecological landscape; determine the ecological landscape construction of highway Visual unit level to guide the highway ecological landscape construction, as the highway ecological landscape construction and implementation of the “yardstick.”
