摘要
以石葵河生态河道治理为例,将工程扰动区划分为河道工程区(Q1)、临时施工道路区(Q2)、弃渣场区(Q3)、取土区(Q4)、临时表土堆场区(Q5)等5个分区。采用层次分析法和CVOR模型,构建山区河道整治工程扰动区植被恢复综合评价模型。结果表明:Q1区植被恢复潜力最强,生态健康等级为健康,属容易恢复区,Q4区、Q5区、Q2区生态健康等级为不健康,植被恢复潜力较弱,生态修复中须加大投资;植被恢复潜力与生态系统健康评价结果基本保持一致,基况条件对植被恢复潜力影响较大,可通过人工干扰提高扰动区植被恢复潜力,提升植被恢复效果。
Taking Shikui River ecological river improvement as an example,the engineering disturbance area was divided into five areas:river engineering area(Q1),temporary construction road area(Q2),waste disposal area(Q3),borrow area(Q4)and temporary topsoil storage area(Q5).A comprehensive evaluation model of vegetation restoration in disturbed area of river regulation works in mountainous areas was established by using analytic hierarchy process and CVOR model.The results showed that Q1 had the strongest vegetation restoration potential,and the ecological health level was healthy,which was easy to recover.The ecological health level of Q4,Q5 and Q2 was unhealthy,and the vegetation restoration potential was weak,so more investment was needed in ecological restoration.The vegetation restoration potential was basically consistent with the ecosystem health assessment results.Base conditions had a great impact on the vegetation restoration potential.Artificial disturbance could improve the potential and effect of vegetation restoration in disturbed area.
