道路选线之后,实际开工时应从植被学的观点预先研究以下问题:(1)、已有植物和植被的破坏限定在最小限度;(2)、建设后的沿道及边坡的绿化方法;(3)、栽树地段的养护;(4)、绿化植物的选择方法。一般道路通过林内时,应设法使采伐面积最小,沿道路尽可能分布阳性树种,不要开通直线,形成风道,要充分保护林缘植被。
After the route selection, the following questions should be studied in advance from the viewpoint of vegetation science when actually starting: (1) the destruction of existing plants and vegetation should be limited to a minimum; (2) the greening methods along the road and slope after construction; 3), conservation of the lot of planting trees; (4), green plant selection method. General roads through the forest, should try to minimize the logging area, distribution of positive trees along the road as much as possible, do not open a straight line, the formation of airways, to fully protect the forest edge vegetation.
