人工边坡生态恢复抗侵蚀效果研究

大规模的基础设施建设形成的岩石边坡,严重破坏了原有植被覆盖的地表,从而引发严重的水土流失。对高、陡、破坏严重岩石边坡的人工修复是生态恢复的重点和难点,但人工边坡又具有不稳定性和较强异质性的特点,通常造成边坡生态恢复效果不佳。边坡的抗侵蚀效果是衡量边坡生态恢复成功与否的外在表现,阐述了边坡坡面地质特征、边坡表面形态、坡面平整程度、坡长、坡度等内在因素和降雨、坡面植被、人工土壤、生态防护工程形式等外在因素对人工边坡生态恢复工程抗侵蚀效果的影响。

Anti-Erodibility Effect of Artificial Slope after Ecological Restoration

Rocky slopes formed by a large scale infrastructural construction had severely destroyed the surface with original vegetation,causing serious soil and water loss.The manual restoration for high,steep and severely destroyed rocky slopes were the key and difficult points for ecological restoration.But,artificial slope had the characteristics of instability and stronger heterogeneity,usually having poor effect of ecological restoration.The effect of anti-erosion of slopes was external performance to examine whether the ecological restoration is successful or not.The paper elaborated the influence of internal factors of geological features,surface morphology,leveling degree,length and gradient and external factors of rainfall,slope vegetation,artificial soil and types of ecological protection engineering to anti-erosion effect of ecological restoration works of artificial slopes.
