| 摘 要： | 于2014年11-12月和2016年7-8月2个阶段对浙江景宁望东垟亚高山湿地省级自然保护区的核心区域进行了系统全面调查和样方调查，对望东垟亚高山湿地植物的生活型进行了统计分析，以群系组为基本单位对该区域的植被类型进行描述，建立矢量模型对其分布格局进行分析。结果表明:该区域植物共计61科122属182种，其中以多年生草本植物为主（51.10%），木本植物也占有较大比例（25.82%）；该区域植被可划分为2个植被型组（山地天然植被型组和沼泽湿地植被型组），4个植被型（常绿针叶林植被型、亚热带山地矮林植被型、森林沼泽植被型和草丛沼泽植被型），6个群系组（黄山松Pinus taiwanensis，浙江红山茶Camellia lucidissima，江南桤木Alnus trabeculosa，沼原草Moliniopsis hui，芒Miscanthus sinensis和华东藨草Scirpus karuizawensis）。分析表明:区域植被的分布表现出优势种较少、盖度大，外貌不整齐，层片结构分化明显的群落学特征。最后，分析了湿地植被分布在人为破坏前后的自我恢复变化过程及规律，针对该区域湿地植被的恢复和保护提出了具体建议。

| Abstract: | Field investigations in the core areas of Zhejiang Provincial Wangdongyang Subalpine Wetland Nature Reserve in Jingning County, China were carried out during November and December 2014 and July and August 2016. The life form functional groups of plants in research area were analyzed, and formation groups as the basic units of vegetation types were described. The distribution patterns were analyzed by establishing a vector model. The results showed that there were 182 species belonging to 122 genera and 61 families in the wetland, most of them being perennial herbs (51.10%) and woody plants also accounting for a large proportion (25.82%). The vegetation in the wetland could be divided into 2 vegetation types (mountain natural vegetation and swamp wetland vegetation), 4 vegetation types (evergreen needle-leaved forest, subtropical mountain scrub, forest swamp, and marsh grass)and 6 formation groups (Pinus taiwanensis, Camellia lucidissima, Alnus trabeculosa, Moliniopsis hui, Miscanthus sinensis, and Scirpus karuizawensis). The results indicated that the distribution of vegetation community in the wetland was characterized by small number of dominant species, high coverage, irregular appearance and stratified structures. Finally, the self-restoration process and pattern of vegetation distribution before and after manmade damages in the wetlands were analyzed, and the solutions to restoration and protection of wetland vegetation were suggested in this study. |
