| 摘 要： | 汤屯高速公路边坡土壤具有偏酸性、有机质低、磷缺乏、铜过量等土质特征。边坡生态防护具有边坡高陡、原生植被彻底破坏、土质贫瘠、缺水、缺肥、生物气候干热胁迫、水土流失严重等难点,遵循交通安全性、景观协调性、生态适应性、生物多样性、经济实用性的原则,提出了以草本植物为主,草、灌、藤有机结合的边坡生态防护植物配置方案,针对全岩质边坡、碎裂结构边坡、土质边坡及边坡的顶部、下沿、平台等部位提出了不同的植物群落配置原则及物种配比方案,对类似工程具有借鉴意义。

| Abstract: | In order to work well the ecological protection of the side-slopes of Tangtun expressway,some investigations on the side-slopes soil were carried out.They include soil sampling,pH mensurating,main nutrient index and main trace elements index analyzing.These results shows that the soil was acidic,low organic,lack of phosphor and excessive of copper.Ecological protection of the slopes have the characteristics of steep slope,destruction of original vegetation,leanness of soil,lack of water and fertilizer,drought and heat stress of ecoclimate,severity of soil and water loss.Considered essential principles such as traffic security,environmental harmonization and economical and practical,a new plant configuration of the side slopes was proposed.The herbages were main measure in the slope ecological protection.The herb,the shrub,and the vine were combined as necessary organic supplement.Aiming at rock slopes,fractured rock slopes,and the soil slopes,the coping,edge and bench of slope,different plant designs were suggested in the paper. |
