2019年白鹤湖湿地植物群落物种多样性

Species Biodiversity of Plant Communities in Baihe Lake Wetlands in 2019

在吉林省莫莫格国家级自然保护区内的白鹤湖湿地,布设了调查样方,于2019年5~10月,对该湿地样方内的植物群落进行了野外调查,测量了地表积水深度,研究了植物群落物种多样性,探讨了其与积水深度的关系。研究结果表明,在调查样方内,共记录植物18种,隶属于12科15属,以莎草科(Cyperaceae)、藜科(Chenopodiaceae)和禾本科(Gramineae)植物为主;由湖滩向湖泊水域方向,从地表无积水到地表积水深度达到42 cm处,依次分布着碱蓬(Suaeda glauca)群落、扁秆藨草(Scirpus planiculmis)群落和芦苇(Phragmites australis)群落;扁秆藨草群落的α多样性水平最高,扁秆藨草群落与芦苇群落的物种组成较相似,碱蓬群落与扁秆藨草群落的物种组成存在明显差异。

Survey quadrats were set up in Baihe Lake wetlands, which located in Momoge National Nature Reserve, Jilin province. A field survey of plant communities in the quadrats was conducted from May to October 2019. The survey did the following: the depth of water on the surface was measured, species diversity in plant communities was studied, and the relationship between plant communities in the wetlands and depth of water on the surface was discussed. The results showed that a total of 18 species in the quadrats were recorded, belonging to 12 families and 15 genera. The main plants were the plants belonging to Cyperaceae,Chenopodiaceae and Gramineae. From the lake beach with no water on the surface to the water of the lake that the depth of the water was 42 cm, the plant communities were Suaeda glauca community, Scirpus planiculmis community, and Phragmites australis community, respectively. The α diversity level of Scirpus planiculmis community was the highest, which was similar in species composition to the Phragmites australis community, the species compositions of Suaeda glauca community and Scirpus planiculmis community were significantly different.
