鄱阳湖湿地植物物种资源及迁地成活率调查OA

This study through literature review and field surveys,an investigation of wetland plant resources in the Jiujiang area of Poyang Lake was conducted to understand wetland plant species diversity.Concurrently,wetland plant collection and ex-situ conservation were carried out to explore the adaptability of wetland plant germplasm cultivated in micro-wetlands.The results showed that the composition of wetland plants in Poyang Lake was rich,mainly including aquatic plants(emergents,floating-leaved,free-floating,and submerged plants),hygrophytes,and some mesophytic herbs.A total of 602 species belonging to 382 genera and 132 families were recorded.Plants of the families Polygonaceae,Rosaceae,Fabaceae,Asteraceae,Poaceae,and Cyperaceae were the dominant wetland groups.A total of 30 wetland plant species were collected and preserved in the project area,of which 24 survived.Among them,15 species,including Vallisneria natans,Persicaria criopolitana,Hydrilla verticillata,and Schoenoplectus tabernaemontani,showed relatively high survival rates,all at or above 80%.Comprehensive analysis indicated that the Poyang Lake wetland harbors a rich diversity of plant species,making ex-situ conservation of certain wetland plants feasible.This study provides data support for future wetland plant conservation efforts.
