为了解澳门大潭山垃圾填埋场的景观恢复情况,采用样方法调查分析了群落的种类组成、垂直结构、区系成分、群落外貌等特征,并对景观恢复进行了评价。结果表明,在1200 m2 样地中共有维管植物83 种,区系成分以泛热带分布属占优势(38.98%),群落外貌主要由草质、单叶和小型叶的小、中高位芽植物所决定。植物群落现状的各指标与自然群落相似,说明自然恢复良好。同时,提出了垃圾填埋场景观恢复的优选物种和改造建议。建议对垃圾填埋场的景观恢复应分期进行,在不同的演替阶段进行适当的人工干预,以加速景观恢复并获得更好的景观效果。
In order to understand the landscape restoration of landfill in Big Taipa Hill, Macau, the species composition, vertical structure, floristic components, and community appearance were investigated by using sampling method. The results showed that there were 83 vascular plants in 12 plots of 1200 m2. The floristic composition of the community was dominated by Pantropical genera, account for 38.98%. The community appearance was determined by the micro- and meso-phanerophyte with herbaceous, simple and micromonophylls. The indexes of the landfill community were similar to that of nature plant community, indicated that the restoration of landfill was good. Based on the current situation of landfill, some preferred species for landscape restoration were selected, and suggestions were given for improving landscape. It was recommended that the landscape restoration should be carried out in stages. To get faster and better landscape restoration, proper manual intervention should be taken at different stages of community succession.
