| 摘 要： | 为了进一步促进边坡生态恢复,引导设计和解决人工植被恢复技术难题,分析边坡植被恢复的特点与难点,论述了边坡植被恢复限制因子选择的原则,在此基础上,构建了边坡植被恢复立地质量综合评价指标体系.采用层次分析法(AHP)进行综合评价,对限制性因子进行了赋权和排序.结果表明:土壤是边坡植被恢复的主要限制因子.立地质量评价指标体系能够为确定边坡植被恢复的难易程度以及优先顺序提供决策支持.

| Abstract: | In order to further improve road slope ecological restoration,guide engineering design and overcome the difficulties in vegetation restoration,the characteristics and difficulties in road slope vegetation restoration are analyzed and the fundamental principles in selecting the limiting factors for vegetation restoration at road slope are discussed in this paper.Based on above analysis and principles,a comprehensive site quality assessment index system for road slope vegetation restoration has been developed.With the application of analytical hierarchy process(AHP) method,the weights of limiting factors are given and scheduled.The results show that soil is a key limiting factor in road lope vegetation restoration.The assessment result demonstrates that the site quality assessment index system developed is useful for analyzing the difficulty level of road slope vegetation restoration and can provide scientific basis for project decision-making. |
