【摘要】 目的：摸清广佛地区湿地植物资源状况及生态环境变化动态，分析其植物多样性资源健康状况。方法：使用典型样地调查法，应用主成分分析进行湿地生态系统健康评价。结果：共记录有湿地植物312种，隶属于90科198属，水生植物93种，湿生植物124种，半湿生植物共有82种，红树类植物13种，乡土植物241种，占比77.24%；外来植物71种，占比22.76%，入侵植物13种。湿地植物群落分为5个植被型组，8个植被型，50个群系（落），13个栽培群系。结论：湿地植物多样性表现为草本层>灌木层>乔木层，50%的样地生态系统呈现不健康状态，33%的样地属于亚健康状态，仅有17%个样地属于健康状态。更多还原

【Abstract】 Objective:To find out the status of wetland plant resources and the change dynamics of ecological environment in Guangzhou and Foshan,and to analyze the health status of plant diversity resources.Methods:The typical sample plot survey method was used to evaluate the health of wetland ecosystem by principal component analysis.Results:There were 312 species of wetland plants,belonging to 90 families and 198 genera,93 species of aquatic plants,124 species of hygrophytes,82 species of semi hygrophytes,13 species of mangroves,241 species of native plants,accounting for 77.24%,71 species of exotic plants,accounting for 22.76%,and 13 species of invasive plants. Wetland plant community was divided into 5 vegetation type groups,8 vegetation types,50 formations(colonies)and 13 cultivation formations.Conclusion:The diversity of wetland plants was herb layer > shrub layer > tree layer. 50% of the sample plots showed an unhealthy state,33% of the sample plots belonged to sub-health state,and only17% of the sample plots belonged to healthy state.更多还原
