摘要
以会仙喀斯特湿地为研究区,采用样地和样方相结合的方法,开展了野外植物调查,研究了植物群落的物种组成、多样性和区系成分。研究结果表明,2022年8月,在会仙喀斯特湿地中分布着39科79属133种植物,被子植物(128种)占绝对优势,而且以挺水植物(77种)为主;优势科为禾本科(Gramineae)和莎草科(Cyperaceae),分别包含了15属31种和7属24种物种;优势属为蓼属(Polygonum)、荸荠属(Heleocharis)和莎草属(Cyperus),都有6种物种;会仙喀斯特湿地中主要有12种植物群落,其中,马来眼子菜(Potamogeton malaianus)群落和五刺金鱼藻(Ceratophyllum demersum var. oryzelorum)群落的多样性水平较高,长苞香蒲(Typha angustata)群落和菰(Zizania caduciflora)群落的多样性水平较低;会仙喀斯特湿地中的植物属区系具有热带特性。
Plant communities in the wetlands have great significance in maintaining the function of wetland ecosystem and protecting the biodiversity.The diversity and floristic composition of plant communities in Huixian Karst wetlands,Guangxi were analyzed in this study.The results indicated that there were 133 species of plants belonging to 79 genera and 39 families in Huixian Karst Wetlands,of which angiosperms belonged to 34 families,74 genera and 128 species,ferns belonged to 4 families,4 genera and 4 species.Gramineae and Cyperaceae were the dominant families,belonging to 15 genera and 7 genera,respectively.Polygonum,Heleocharis,and Cyperus were the dominant genera.Emergent plants are the most abundant,there were 77 emergent plants,accounting for 57.9%of the total species.The flora of the plants in Huixian Karst wetlands was divided into 10 types and showed obvious tropical subtropical characteristics.
