Study of slope types and the effectiveness and target communities of green plants in slope restoration
[Objective]The aim of this study was to investigate the effectiveness of green plants and damaged slopes for ecological restoration and to explore the main basis for rebuilding the target plant community.[Method]The effectiveness of green plants and damaged slopes in slope restoration was analyzed by Analytic Hierarchy Pro-cess (AHP) method,and the target plant communities were constructed by selecting pioneer and constructive plant species in order of effectiveness.[Result]This study found that the volumes of damaged highway slope bodies were large and mainly located in economically developed and densely populated areas,which had a high impact on the envi-ronment and social economy.And therefore the restoration of damaged highway slopes had a quick effect and the con-tribution rate to the overall target was as high as 50.24％. The effectiveness of different species and life types of plants varied greatly and could be combined in a variety of ways,but the most effective plant for the type of restora-tion should be preferred as the green plant for the target community.[Conclusion]The plant communities of "shrub-herb" type,"arbor-shrub-herb" type,and "liana-herb"type were proposed as the target plant communities for the restoration and reconstruction of mountainous highway slopes,accumulated slopes of abandoned mine,and rocky slopes of quarries respectively.
