摘　　要：通过对湖南几条已建高速公路绿化现状实地调查与分析,结合宁道高速路域环境,以宁道高速生态快速恢复为目的,提出了中央分隔带绿化首先应满足分隔及防眩作用,避免重美观轻功能的构思;边坡绿化植物选择应以适应性强的乡土植物为主,适当引进外来优良树种,并根据不同的边坡类型采取不同的绿化措施。Ecological protection in expressway construction has been given increasing attention, selection of plants and deployment design play a vital role in the ecological restoration. Onsite investigations were carried out on afforestation of the constructed expressways in Hunan Province to identify successful experiences and existing problems. Considering the environmental conditions of Ning-Dao Expressway, the function of central reserve of the expressway should be focused on separation and antidazzle, therefore to avoid over emphasizing on its visual beauty and ignoring its functions. Native plants which are well adapted to local conditions should be used for roadside plantings, and exotic trees can be used as appropriate. Moreover, different planting measures should be taken according to different types of roadside slopes.
