提高高速公路绿化植物成活率的重要控制环节 Create green traffic, beautify the driving environment, improve the construction of road is destroyed when the natural ecological balance, promoting the road slope stability, enhance the greening projects, such as the traffic line of sight guidance function to improve occupies very important position and role. And the key to how to guarantee the greening projects, namely improve the planting survival rate problem, is the current need serious study to explore an important issue. 1绿化模式 1 greening patterns 高速绿化带可以分为中央分隔带、边坡绿化、两侧护坡道绿化和两侧边沟外平台绿化四部分。 High-speed green belts can be divided into the central separation zone, slope greening, slope protection on both sides of the road greening, and two side channel platform greening four parts. 1、中央分隔带 1, the median 中央分隔带集隔离、防眩、景观等多种功能于一身,作为高速绿化的重要部分,直接着影响高速公路的形象。为了起到景观优化效果及防眩作用,同时缓解行车人员疲劳,满足驾驶员在自然柔和的光线下行驶的要求,中央隔离带须设计成一条稍高于防护板的绿色带。 Median set isolation, anti-glare, landscape and other functions in one, as an important part of highway greening, directly affect the image of highway. In order to have landscape optimization effect and anti-dazzle effect, alleviate fatigue driving personnel, at the same time meet the driver at the request of the natural soft light driving, the central isolation belt protective plate shall be designed to a slightly higher than the green belt. 高速中央隔离带株距可以设计为4m,高度1.8m~2.0m,防眩角度α=7.1°,则纵向防眩最小距离为40~96m,起到了防眩效果。同时考虑到观赏性,在整体统一的基础上,采取多种搭配组合,依据不同季节交替栽种不同植物,形成不同景致的植物群落。 The central isolation belt planting distance can design is 4 m, height 1.8 m ~ 1.8 m, anti-dazzle Angle alpha = 7.1 °, the longitudinal anti-dazzle minimum distance of 40 ~ 96 m, played the anti-dazzle effect. Considering the spectator at the same time, on the basis of the unified whole, take a variety of combinations, according to different seasons alternating plant different plants, forming different landscape plant community. 2、边坡及边沟外平台绿化 2, outside platform edge slope greening 为了达到防止雨水冲
