| 摘 要： | 以河北省坝上风电场建设区为研究对象,探讨风电场建设区水土流失特点、分区、防治重点及植被恢复措施。结果如下：风电场建设区水土流失特点为风电场工程的特殊性与坝上水土流失特征的相互耦合的表现;风电场建设区水土流失特点表现为点状与线状侵蚀并存,风蚀与水蚀共存,植被破坏点多面广、植被恢复难度大,土石方量较小、弃渣相对较少,水土流失重点在施工建设期等;风电场建设区的水土流失主要来自升压站、风机区、施工生产生活区、道路区、集电线路区和弃渣场等6个区域,不同区域的水土流失特点和防治重点各有侧重;坝上风电场建设区的植被恢复可采取封育恢复自然植被,清理表土集中覆盖、利用土壤种子库恢复植被及人工植被建设3类途径。

| Abstract: | Based on project region of wind power field in Bashang,the soil erosion characteristics,zoning,key protection area and vegetative restoration measures are studied.The results show that: the soil erosion of wind power field construction region is intercoupling with particularity of wind power field and characteristics of soil erosion of Bashang region.The erosion characteristics of wind power field in construction region is coexistence of wind erosion with water erosion,coexistence of point erosion with line erosion,and vegetation restoration is difficult,earthwork and waste slag are less.Soil erosion are mainly occurred in six regions which is road,fans area,working and living region,substations,overhead line area and abandoned dreg site.The erosion characteristics and controlling emphasis are different in regions.The vegetation restoration can be resumed with three kinds measures including fence closing,using of soil seed bank to restoration natural plant,and constructing artificial vegetation in wind power field construction area of Bashang region. |
