| In recent years,due to the rapid development of society,more and more scholars are paying attention to the research and development of wetland ecology.At present,scientific research focuses mainly on wetland protection,ecological restoration and utilization.Wetland plants are rich in species and have three major advantages: strong adaptability,high ornamental value,and high economic benefits.Wetland plants are indispensable elements in wetlands and have high research value.This study carried out field surveys on wetland plants in the Taiping Lake Wetland Park.Based on the wetland conditions,a combination of sampling and sampling methods was used.Statistics and quantitative ecology were used to collate and analyze the data.The characteristics of plant community and diversity of wetland in Taiping Lake Wetland Park provide guidance for the ecological restoration of Taiping Lake National Wetland Park wetland plant and accelerate the evolution of plant communities in Taiping Lake National Wetland Park wetland.Taiping Lake National Wetland Park wetland plant species composition,floristic characteristics,plant community characteristics,plant community diversity characteristics and wetland ecological restoration are the main research content of this article.By studying the wetland plant communities in the Taiping Lake Wetland Park,the results of the survey indicate:1)Taiping Lake National Wetland Park Wetland has a rich variety of plants,totaling 119 kinds of wetland plants,belonging to 47 family and 97 genera.Among them,angiosperms include 40 families,90 genera and 112 species;gymnosperms,1 family,1 genera and 1 species;ferns,6 families,6 genera and 6 species.2)Taiping Lake National Wetland Park has many floristic geography types,and its families and genuses are distributed in different types.The distribution of the species is regionally significant and has a tropical nature.Genus is a type of intermittent distribution.The 41 families of wetland seed plants were divided into 4 distribution types and 2 variants.91 genera of wetland seed plants were divided into 12 distribution types and 4 variations.Tropical genus and temperate genus are dominant species,and tropical components are slightly higher than temperate components,indicating that the flora of the genus Taiping Lake Wetland has obvious transition from tropical to temperate.3)Wetland plant community characteristics analysis results show that the wetland plant communities in the Taiping Lake Wetland Park are divided into four types: wet scrubs,wet herbs,aquatic and terrestrial converging and aquatic species.The wetland communities are mostly low bushes.The communities are relatively neat in appearance,relatively low in size,large in coverage,and densely planted.The species richness of the community is relatively low,and the dominant species has a high degree of dominance.Most of the above-ground communities have little obvious stratification.4)The results of community diversity studies show that the species richness index and the community diversity index are low,the differences between the various plots are relatively large,and the plant distribution is more uniform.In the shallow water area,the plant species are abundant,distributed evenly,and their dominance is low,with high diversity.Areas with significant changes in water levels have fewer plant species and less diversity.5)Taiping Lake belongs to the youth of the lake.The future evolution trend of wetlands is that the area of water areas is gradually shrinking,and the land-water transition zone is expanding.The succession of wetland plant communities to the later stage was dominated by the reed community,the pupa community,the lobelia community,the philodendron philoxeroides community,and the pond floristic community.Wetland restoration should select suitable plant species,conduct reasonable combination of multiple species,give full play to the coordination among wetland plants,and achieve the effect of wetland ecological restoration. |
