陕西黄土高原地区高速公路高陡边坡绿化技术

从陕西省黄土区高速公路高陡边坡土壤干旱、瘠薄、陡峭的生态环境条件出发,提出采用雨水叠加利用和易地利用模式来提高平台土壤水分含量;铺设一维网垫草皮和土工格室;增施有机肥料,培肥地力;选择适生乡土树草种等技术措施,以提高高陡边坡绿化植物的成活率和保存率。

Afforestation Technology on High and Steep Slope in Loess Plateau of Shaanxi Province

Based on the arid, barren, precipitous ecological environmental conditions of expressway high and steep slope soil in the loess plateau of Shaanxi Province, the paper proposes some measures as follows: (1) to adopt the rainwater to superpose utilization and transposition locality utilization to raise the content of soil moisture of the terrace soil; (2) to lay the two-dimensional network cushion and geotechnological dose of rooms; (3) to reconstruct the organic fertilizer, and to raise the soil fertility; (4) to choose the suitable tree or grass species to native soil, and apply some technological measures in order to improve the afforest survival and preservable rate on high and steep slopes of the highways.
