摘　　要：本研究的目的在于调查困难立地条件下的赣北地区10条高速公路边坡植物群落,筛选出边坡乔木层,灌木层、草本层的优势种植物,总结江西省几十年的高速公路边坡植被恢复模式实践经验,将植被恢复情况较好的边坡整理归纳出生态恢复模式,对植被恢复较差的边坡提出针对性和可操作性的优化对策,为后期高速公路边坡植被恢复及养护工作提供参考,以实现江西省高速公路生态效益、社会效益、观赏效益的最大化。The study investigated the plant communities of 10 expressway slopes in northern Jiangxi,screen out the dominant species of tree layer,shrub layer and herb layer of the slope,to summarize the practical experience of the vegetation restoration model of expressway slopes in Jiangxi Province for decades.The research summarized the ecological restoration model of the slopes with good vegetation restoration,and put forward targeted and operable optimization countermeasures for the slopes with poor vegetation restoration,so as to provide reference for the vegetation restoration and maintenance of expressway slopes in the later period,and maximize the ecological,social and ornamental benefits of expressways in Jiangxi Province.
