恢复生态学理论在水电工程扰动区边坡生态修复中的应用

Application of Restoration Ecology to Slope Ecological Protection in Disturbance Area of Hydropower Project

随着我国水电工程的兴建,出现了大量由于施工开挖而产生的裸露边坡,极大地改变了区域生态环境。针对水电工程扰动区边坡的特点和恢复目标,从6个方面总结了水电工程对生态环境的影响,并从恢复生态学理论出发,以向家坝水电工程扰动区2个具有代表性的边坡生态修复工程为例,阐述了恢复生态学理论在水电工程扰动区边坡生态修复中的应用。结果表明:采用2种边坡生态修复技术对边坡样地实施了生态修复并采取了调控措施后,生态景观效应明显,较好地实现了边坡治理的目的,为水电工程扰动区边坡生态修复提供了有价值的参考。

The construction of hydropower projects gave rise to a large number of bare slopes due to excavation. They have greatly changed the regional ecological environment.In this paper we summarized the influence of hydro-power project on ecological environment in six aspects.Moreover,we took two representative projects of slope eco-logical restoration in the disturbance area of Xiangjiaba Hydropower Project as examples,and expounded the appli-cation of restoration ecology to slope ecological protection.By using two different technologies （to grow plants a-mong concretes and to spray thick base materials）of slope ecological restoration and taking artificial control meas-ures,the ecological landscape effect is obvious and the slope is well restored.This research could be a good refer-ence for ecological restoration in disturbance area of hydropower project.
