摘要
为评价高速公路路基边坡生态防护效果,从护坡效果、生态效益、景观效果3个方面,通过专家咨询,建立层次分析法与模糊综合评价相结合的路基边坡生态防护效果评价体系,并将其应用于贵州省某高速公路路堑边坡的评价。评价结果表明:护坡功能是影响边坡生态防护效果评价的最重要因素,其次是生态效益,景观效果所占比重最小;该高速公路路堑边坡生态防护效果良好。
In order to evaluate the effects of ecological protection of roadbed slopes of expressways,this paper establishes an evaluation system for the effects of ecological protection of roadbed slopes combining the analytic hierarchy process with fuzzy comprehensive evaluation from 3 aspects including slope protecting effects,ecological benefits and landscape effects via expert consultation,and applies the system in evaluation for roadbed slopes of some expressway in Guizhou Province.The results of evaluation show that the slope protecting function is a most important factor that affects evaluation for the effects of ecological protection of slopes,followed by ecological benefits,and the landscape effects occupy the smallest proportion;the ecological protection of roadbed slopes of the expressway exhibits perfect effects.
