摘要
为促进九寨沟国家级自然保护区震后高陡裸岩边坡快速覆绿,加速景观的生态恢复过程,在参考文献和实地调查的基础上,选取该区域较为常见的30种乡土苔藓植物,运用层次分析法,基于抗逆能力、易获得性、生态功能、繁殖能力、生物量积累和美观感6个方面构建出18项筛选评价指标体系。结果表明:根据综合评价分值将覆绿苔藓植物分为4个等级,最终筛选出适用于九寨沟震后覆绿5种苔藓植物:东亚砂藓(Racomitrium japonicum)、大灰藓(Hypnum plumaeforme)、美灰藓(Eurohypnum leptothollum)、阔边匐灯藓(Plagiomnium ellipticum)和长叶青藓(Brachythecium rutabulum)。研究结果可为九寨沟及其周边高寒脆弱生态系统无土壤基质的生态环境修复提供备选物种的参考。
In order to promote the rapid greening of the steep bare rock slopes in the Jiuzhaigou National Nature Reserve after the earthquake,and accelerate the ecological restoration process of the landscape,based on references and field investigations,30 common native mosses in the region were selected,and an evaluation index system of 18 items was constructed based on six aspects including resistance ability,availability,ecological function,reproductive ability,biomass accumulation,and aesthetic appeal,using the Analytic Hierarchy Process(AHP).The results indicated that:according to the comprehensive evaluation score,the mosses were divided into four grades.Finally,five species,Racomitrium japonicum,Hypnum plumaeforme,Eurohypnum leptothollum,Plagiomnium ellipticum and Brachythecium rutabulum were selected.The results should provide an objective guidance for future ecological restoration without soil in Jiuzhaigou and its surrounding cold fragile ecosystem area.
