滩涂湿地植被是鱼类产卵的重要介质和场所,与长江江豚饵料密切相关。调查滩涂湿地植物资源分布现状,是长江江豚(Neophocaena asiaeorientalis)栖息地状况治理与评价的重要基础与前提。于2023年4月、7月、10月和12月,采用定点样线和样方相结合的调查方法,对长江安庆段滩涂湿地开展了维管植物资源调查,并基于调查结果分析了该区域维管植物的组成特征和区系类型。研究结果表明,长江安庆段滩涂湿地共记录维管植物242种,隶属于58科164属;蕨类植物有6科7属7种,裸子植物有1科1属1种,被子植物有51科156属234种;菊科(Asteraceae)、禾本科(Poaceae)和莎草科(Cyperaceae)为优势科,分别包含35种、32种和27种物种,优势属不明显;区系组成上维管植物科和属都具有隐域性及具有热带成分和温带成分的双重性质;长江安庆段滩涂湿地中的维管植物物种丰富,植被覆盖率较高,不仅可以改善长江水质,又可以为许多鱼类提供适宜的繁殖和索饵场所,对于维系长江江豚的食物资源和栖息环境具有积极意义。
Investigation and Flora Analysis of Vascular Plant of Mudflat Wetlands in Anqing Section of the Yangtze River
Mudflats vegetation is important spawning medium and place for fish,which is closely related to the bait for Yangtze finless porpoise.Investigating the distribution of plant resources in the mudflat wetlands were important foundation and prerequisite for evaluating and managing the habitat status of the Yangtze finless porpoise.In the Anqing section of the Yangtze River mudflat wetland,the wild vascular plants were investigated using the combination of sample lines and sample plots surveys method to explore the composition characteristics and flora types,from April to October,2023.The results showed that 58 families,164 genera and 242 species of vascular plants were recorded in the mudflat wetland.Among theme,there exist ferns plants of 6 families,7 genera and 7 species,gymnosperms plants of 1 families,1 genera and 1 species,Angiospermae plants of 51 families and 156 genera and 234 species.Asteraceae,Poaceae and Cyperaceae are the dominant families,containing 35 species,32 species and 27 species respectively,and the dominant genera are not obvious.The area-types of families of mudflats wild vascular plants were divided into 4 areal types and 1 subtypes,that of genera were divided into 12 areal types and 5 subtypes.And it also shows obvious concealment and the dual nature of tropical and temperate zone.In general,the mudflats wetlands in the Anqing section of the Yangtze River have a high level of vascular plant species diversity,and the natural area with large plant cover.Higher vegetation coverage not only to improve water quality of the Yangtze River,but also provides a suitable breeding and spawning ground for many fish,which own positive significance to maintain the food resources and habitat for the Yangtze finless porpoise.
