寒、旱、沙化黄土区高速公路边坡植被绿化技术研究

Study on Afforestation for the Highway Slope with Cold,Drought and Desertification Conditions in the Loess Areas

采用调查乡土种和当地已建高速公路边坡绿化情况相结合的方法,在对京大高速、得大高速、大同环城高速等边坡的绿化植物进行调查的基础上,筛选了适合寒、旱、沙化黄土区高速公路边坡植被绿化植物,认为柠条、沙棘、沙地柏等作为优势绿化植物较为科学。探讨了其育苗、栽植和管理技术,进而分析了其植被绿化效果。

By using the methods of combined investigation native tree species and local highway slope plant species,the field vegetation survey were conducted at the slope of Jingda,Deda and Dotong beltway highway.The dominant species of Caragana korshinskii,Hippophae rhamnoides and Sabina vulgaris were screened out to fit for the revegetation on the highway slope with cold,drought and desertification conditions in the loess areas,the nursery,planting and management techniques were discussed and theirs revegetation effects were analyzed.
