摘要

采用现场调查、观测、试验等多种试验方法，对黄延高速公路绿化植物、边坡土壤理化性质以及植物群落组成进行了研究。通过分析，总结了中央分隔带、平台和边坡绿化植物种类以及边坡有效配置模式，分析了土壤养分贫瘠的原因和提高措施。在此基础上提出土壤肥力与植物恢复是相辅相成的，土壤肥力随人工植被建立时间的延长而逐渐恢复;随着时间序列的延长，其物种数目和比例也发生较大变化，有利于护坡植物群落最终实现结构稳定。

Abstract

Based on in situ investigation，observation，and test

green plant

slope soil physical and chemical properties

and plant community composition on the Huangling --Yan'an Highway are studied. Through analyses

plant species in the central reserve

platform and slope

and the advanced allocation model are summarized and the reasons of soil nutrient pool and improving measures are analyzed. Accordingly，several relevant conclusions are made. Soil fertility and plant restoration is complement and soil fertility is gradually restored with time after artificial vegetation construction. The number and proportion of species have a great change with the passage of time

which is beneficial to plant community of slope to reach structural stability.
