空心砖绿化技术在公路边坡景观修复中的应用
pplication of Air Bricks for Planting Roadside Vegetation on Landscaping Restoration in Shenyi Highway in China\
在陡峭的公路两侧进行植被重建是公路环境保护最棘手的问题之一。为了探索适宜公路两侧陡壁绿化的植物栽培技术,2006年至2008年间,我们在湖北省神农架旅游区开展了空心砖护面墙绿化栽培技术试验研究。该技术在空心砖填土后种植草本植物,然后以阶梯式或光滑斜坡式嵌入公路两侧陡壁表面。研究结果显示,与传统的栽培技术相比,该技术有效促进了植物根系的生长发育、改善了边坡植被覆盖度、增加了坡面植物生物量和种子产量,非常适宜土壤瘠薄的湿润山区公路两侧陡壁绿化和植物重建,同样也适宜世界上类似地区公路两侧绿化和植物重建。由此可见,空心砖护面墙绿化栽培技术是湿润山区公路建设边坡植被修复和景观保护的重要技术途径。
Establishing vegetation cover on steep roadside slopes is a challenging task in mountainous regions of China. To resolve the issue, two new planting techniques were developed to increase vegetation cover on these slopes, in which planters fill the holes in air bricks with soil, then plant grass or herbaceous species in the soil. Two variants of this technique (one in which the air bricks form a stair-step pattern, and the other in which they form a smooth slope) were tested in a warm area near Shennongjia (Hubei Province) between 2006 and 2008. The new planting techniques promoted root growth, vegetation cover, and biomass and seed production compared with the conventional planting technique. This suggests that the air brick technique is more suitable for the study area, where the natural soils are thin, and may prove suitable for similar areas elsewhere in the world. The new techniques thus represent a potentially valuable alternative for vegetation restoration and landscape conservation in mountainous zones during and after highway construction.
