植被覆盖是公路边坡防护的措施之一,而土壤中的有机质含量对促进植物生长至关重要. 为此,采用对比试验的方法,研究了在土壤中铺设锯末后,有机质的流失情况以及植物的生长状况. 结果表明:在同样气候条件下以及植物生长周期内,未铺设锯末土壤中的有机质下降较多;气温较低月份,铺设锯末土壤中的有机质要高于未铺设锯末土壤25%. 试验结果对于坡面工程的水土保持具有推广应用价值.

Vegetation coverage is one of the protection measures for highway slope, and the soil organic content plays an impor-tant role in promoting vegetation growth. For the slope projects, we study the organic content variation law in soil after the saw-dust is mixed into the slope soil, and the vegetation growth is observed and compared. The results show that for the same vegeta-tion growing period and climate condition, the soil without sawdust losses more organic content;in cold days, the organic matter in the soil containing sawdust is 25% more than that in the soil without sawdust. The results have significant meanings for soil and water conservation of highway slope projects.
