摘 要：
2014-2015年,采用线路调查法和样方调查法,对广东省乳源南水湖湿地维管植物进行调查。结果显示,该湿地有维管植物187种,隶属于67科122属;以草本植物为主;湿生植物比例最大。优势科是莎草科Cyperaceae、禾本科Poaceae、水龙骨科Polypodiaceae等,优势属是莎草属Cyperus、凤尾蕨属Pteris、蓼属Polygonum等。南水湖湿地维管植物表征科的地理成分有6个分布型1个变型,热带成分占83.33%;维管植物属的地理成分包括13个分布型7个变型,以热带成分为主体。与其他高纬度地区及同纬度的内陆地区相比,南水湖湿地表现出更强的热带性质;不同地区植物区系聚类分析表明,植物属区系地理成分变化趋势跟地理位置和纬度有关。

摘 要：
Investigations on vascular plants were carried out from 2014 to 2015 in wetland of Nanshui Lake of Gurangdong province by route and quadrat survey. The result demonstrated that there were 187 species of vascular plants, belonging to 122 genera and 67 families. Herbs and hygrophyte occupied the largest proportion of vascular plants. Gramineae, Cyperaceae and Polypodiaceae, etc. were dominant families, and Cyperus, Pteris and Polygonum, etc. were dominant genera. There were 6 geographical distribution patterns and 1 variant in typical families, tropical elements accounted for 83.33%. The geographical elements of surveyed vascular plants consisted of 13 distribution patterns and 7 variants, among them, tropical elements were dominant. Flora of Nanshui Lake showed significant tropical characteristic than that of wetland at higher and similar latitude inland. The result of clustering analysis showed that the flora composition in wetland had relationship with geographic position and latitude.
