高速公路植被生态护坡水土保持效益关键因素调查研究——以山西省阳蟒高速为例

Investigation and Research on Key Factors of Efficiency of Soil and Water Conservation of Expressway Slope Protection by Vegetation Ecology:Case Study of Yangmang Expressway in Shanxi Province

以山西省阳蟒高速公路植被生态护坡为研究对象,对分别应用双聚交联型土壤固化生态修复技术、客土喷播生态修复技术、植被穴栽生态修复技术3种植被生态修复技术的植被生态护坡开展实地调查,分析不同植被生态修复技术对绿化植被生长情况及边坡坡面侵蚀情况的影响,探讨不同植被生态修复技术的水土保持效益,研究得出影响高速公路边坡水土保持效益的关键因素,为同类型高速公路边坡植被生态修复及水土保持防治提供参考依据。

Based on the slope protection by the vegetation ecology on Yangmang Expressway in Shanxi Province,this paper conducted the field investigation of ecological slope protection using three kinds of technologies of biopoly-cross-linked soil curing ecological restoration,soil-spraying ecological restoration,and vegetation planting ecological restoration to analyze the influences of different ecological vegetation restoration technologies on the growth of green vegetation and the erosion of the slope surface and discuss the efficiency of these technologies on the soil and water conservation.This paper obtained the key factors that influence the efficiency of soil and water conservation of expressway slopes,providing a reference for the vegetation ecological restoration and soil and water conservation prevention for similar expressway slopes.
