摘　　要：山区公路建设弃渣场常由石渣堆砌而成,其结构松散、孔隙率大、渗透性强,自然生态恢复极为困难。而客土培育技术常用于生态条件恶劣的区域生态治理。以湖北省宜昌某高速公路弃渣场为依托,应用客土灌木化施工工艺,以植被覆盖度和高度作为观测指标,开展了弃渣场生态恢复试验,主要研究灌木生长特点及其对土壤侵蚀的影响,提出适宜宜昌地区弃渣场生态治理的植被类型,对区域内弃渣场生态恢复工程有一定指导意义。The discarded soil fields located at the highway are consisted of discarded soil in the mountainous area,which are loose structure,big porosity and strong permeability. These features and conditions lead to difficulties of its natural ecological restoration. Foreign soil cultivation technology was suggested as a suitable method to discarded soil field ecological restoration test,because of its good effect in the mountainous area. Based on project of the expressway discarded soil field in Yichang area,Hubei Province,the foreign soil planting technology was applied to practice in the test. Experiments were conducted to investigate the shrubs growth characteristics and effect on soil erosion by observing the coverage and height of the shrubs in the result. According to the test result,the research puts forward conformable vegetation types,also has guiding significance to discarded soil field ecological engineering in Yichang area.
