- Abstract
The Nanhu Wetland Nature Reserve is located in the southeast of Gongqing City, Jiangxi Province. It is an important part of Poyang Lake. In this study, the wetland vascular plants in this reserve area were investigated.The results show that : CD there are 418 species belonging to 247 genera and 87 families in the reserve.Among them, they include 10 pteridophytes species in 10 genera and 9 families and 408 species of angiospe rms from 237 genera and 78 families ( including 287 species of dicotyledons belonging to 173 genera and 61 families and 121 species of monocotyledons belonging to 64 genera and 17 families).The pre ponderant families include Compositae ( 44 species), Gramineae ( 43 species), Cyperaceae (28 species) and Polygonaceae (25 species). They play an important role in the wetland communities. And the main constructive or dominant species of the communities are from these families.@ At family level, the dominant distri bution types are the world wide(43 families) and the pan tropical distribution (18 families) ; while at genus level, the dominant distribution types are t he pan tropical(59 genera) and the world wide distribution (55 genera).The ratio value of the tropical distribution and the temperate distribution (R/T) is 1.26, which in dicates that the tropical distribution is slightly dominant, showing a transit ional characteristics form tropic to temperat e of this region.® There are 26 species alienor invasive plants in the reserve,among which Daucus carota L.,Geranium carolinianum L., Alternanthera philoxeroides (Mart.) Griseb.and Soliva anthemifolia CJ uss.) R.Br.are the most serious. In recent years, the invasive plants, especially Sorghum halepenses ( L.) Pers.And Solidago canadensis L., have expanded significantly in the reserve area. Hance, it is necessary to strengthen the Surveillance and control of the invasive species in this area.
