浙西南山区干线公路绿化乡土树种应用及其配植模式

Planting Patterns and Utilization of Native Tree Species in Greening of Arterial Highways in Mountainous Areas in Southwestern Zhejiang Province

为促进乡土植物在公路绿化中的推广应用,对浙西南山区主要干线公路绿化现状进行了调查分析,结果发现:该地区公路绿化乔木和灌木乡土树种的乡土化率分别为53.4%和33.4%。通过查阅当地植物志及相关文献资料,基于此地区公路干线生境条件,并结合不同交通节点功能区特点,总结了适合该地区公路绿化的主要乡土树种及其种植模式,以期为公路绿化建设及其科学管护提供借鉴。

To promote the utilization of native tree species in driveway greening,the greening conditions of arterial highways in southwestern area in mountainous areas of Zhejiang province were investigated.The results showed that the ratios of native arbor tree and shrub species were 53.4%and 33.4%respectively.According to the local flora and related literature,based on consideration of the site conditions and functions of switching nodes,the main indigenous tree species and their planting patterns were proposed in this paper.This paper could provide effective help to the greening construction and rational management ofarterial highways in the future.
