摘要
通过层次分析法构建延庆县山区公路生态绿化乡土植物选择体系,从植物的生态适应性、生物学特性和综合效益方面,对延庆山区公路沿线调查乡土植物种进行综合评价,选出综合特性优良的10种乔木、10种灌木和20种草本。从海拔、坡向、坡位和边坡类型4方面,对调查样方进行聚类分析,确定各植物种的适宜立地类型,为延庆县山区公路生态绿化乡土植物的选择提供重要依据。
This paper via the Analytic Hierarchy Process（AHP） builds a selection system of ecological greening indigenous plants on highways in mountainous areas of Yanqing County,carries out comprehensive evaluation for species of indigenous plants under investigation along highways in mountainous areas of Yanqing County based on ecological adaptability,biological characteristics and synthetic benefits of plants and chooses 10 species of arbor,10 species of shrub and 20 species of herbage with excellent comprehensive characteristics.The paper conducts a cluster analysis for investigated species from 4 aspects,i.e.altitude,slope direction,slope position and slope type to determine site types appropriate for various plant species and to provide an important basis for selection of ecological greening indigenous plants on highways in mountainous areas of Yanqing County.
