2008年春,我们工厂新区建成。在厂房北边一段200余米长的路段,厂房和院墙之间只有8米宽,显然没有空间栽植行道树或花木了。为了增加绿化覆盖率,我们决定对这段院墙进行垂直绿化。修筑这段水泥路时,我们特意在院墙边留出30厘米宽的种植带。种植带采用沉降槽式,低于路面20厘米,这样一是泥土落叶不易被风刮到路面上,污染路面;另一个好处就是能充分利用雨 The spring of 2008, we completed the new factory area. In the north of the plant a section of more than 200 meters long, only 8 meters wide between the plant and the courtyard wall, apparently there is no space planted trees or trees. In order to increase the greening coverage, we decided to vertically green the courtyard wall. When building this section of concrete road, we deliberately set aside a 30 cm wide planting belt beside the courtyard wall. The planting belt adopts the sedimentation trough type, which is 20cm below the road surface. In this way, the soil leaves are not easily blown onto the road surface to pollute the road surface; another advantage is that it can make full use of the rain
