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.
