摘　　要：近年来不合理开发利用湿地的问题日益严重,人们对湿地的片面认识更加速了破坏湿地。乡土植物能更好地适应当地的环境,选择适用的乡土湿生植物可能是恢复退化湿地的关键途径。文章利用植物志在线网站结合文献,分析华南地区湿生乡土植物资源及其区系特征,为华南地区利用乡土湿生植物和恢复湿地生态系统提供依据。结果如下:(1)华南地区湿生乡土植物资源丰富,共有128科430属1080种;被子植物占华南地区湿生植物总种数的95%以上,是整个区域的主要组成部分。(2)华南地区湿生植物以草本为主,共有959种,占总种数的88.7%。(3)区系类型复杂,热带成分占优势地位;在科级水平,华南地区乡土湿生植物以热带分布科为主;在属的水平,泛热带分布占比高且有多种温带成分的组成。In recent years,the problem of unreasonable exploitation and utilization of wetlands has become increasingly serious,and the general facial understanding of wetlands has accelerated the destruction of wetlands.Native hygrophytes can better adapt to local environments,so selecting adequate native hygrophytes is possibly the key way to restore degraded wetlands.In this paper,the florae and their floristic characteristics in South China were analyzed by reviewing e-Floras and literature,to provide the basis for the utilization of native florae in South China and the restoration of wetland ecosystems.The results are as follows:(1)South China was rich in native hygrophyte resources,with 128 families,430 genera,and 1080 species;Angiosperms accounted for more than 95%of the total species of wetland plants in South China,which were the main component in the whole area.(2)Herbaceous plants were the dominant species in South China,accounting for 88.7%(959 spp.)of the total.(3)The floristic types were complex,and tropical components were dominant;At the family level,the native hygrophytes in South China were mainly tropic-distributed families.At the genus level,the pantropical flora was high in proportion and has a variety of temperate components.
