摘" 要:該文詳細闡述生態防護在高速公路工程建設中的重要性,主要通過植被的蓄水、保肥和固土功能來加固和保護邊坡。這種防護作用主要體現在根系的力學效應和植被的水文效應2個方面。同時,深入探討公路路基邊坡生態防護技術及其機理,并試圖將這些知識應用于提升生態防護技術手段。為實現此目標,結合多年野外工作實踐經驗,以公路邊坡植物防護技術為研究對象,從多角度對邊坡植樹種草防護技術的發展和生態防護機理進行深入分析。

Abstract: This paper expounds in detail the importance of ecological protection in highway engineering construction, mainly through the functions of water storage, fertilizer conservation and soil consolidation of vegetation to strengthen and protect the slope. This protective effect is mainly reflected in two aspects: the mechanical effect of root system and the hydrological effect of vegetation. At the same time, this paper deeply discusses the highway roadbed slope ecological protection technology and its mechanism, and tries to apply these knowledge to improve the ecological protection technology. In order to achieve this goal, combined with many years' practical experience in field work, taking the plant protection technology of highway slope as the research object, the development of recommended protection technology and ecological slope protection mechanism of slope tree planting are analyzed from multiple angles.
Keywords: slope ecological protection; tree planting recommendation technology; ecological slope protection technology; highway; highway roadbed
截至2022年底,我國公路總里程達到535萬km,十年增長112萬km,其中高速公路通車里程17.7萬km,穩居世界第一。生態文明是全面建設社會主義現代化國家的重要議題之一[1]。隨著社會公眾對生態環境保護意識的日益增強,高速公路邊坡防護的規劃與設計,以及生態護坡工程的興建等正逐步受到廣泛關注[2]。高速公路邊坡的生態保護,作為一種創新的護坡方式,利用植被的自然機能提升邊坡的穩定性和防護效能[3]。邊坡植物防護的核心目標在于土壤固結與邊坡穩定,有效防止水土流失,同時也為環境美化提供了輔助功能。近年來,高速公路網絡的擴張對周邊原始地形和自然生態帶來了顯著影響[4]。因此,在開展高速公路邊坡防護工作時,必須同步關注環境質量的保護與提升,秉持“保護環境光榮,污染環境可恥”的原則,采取恰當的預防和保護措施,如避開生態敏感區域,以實現高速公路的持久性、安全性、舒適性和便捷性?!?br>
