摘要
广西大新黑水河国家湿地公园为典型的桂西南石灰岩地貌河流湿地,生态系统完整,生境特殊。为给其资源保护提供参考,以2017—2018年黑水河湿地公园本底和监测调查数据为基础,分析黑水河湿地公园维管植物多样性、湿地植物群落种类和野生种子植物区系。结果表明,公园内维管植物物种丰富,有122科375属492种;其中,野生维管植物有119科365属477种,野生湿地维管植物有43科83属101种。野生种子植物以少种科和单种科为主,占野生种子植物总科数的72.17%;以单种属为主,占野生种子植物总属数的78.98%。湿生植物群落和水生植物群落面积占湿地植被总面积的比例分别为67.37%和32.63%,以湿生植物群落为主。野生种子植物区系科、属的R/T值分别为4.45和4.24,植物区系热带成分及特征明显。
Guangxi Daxing Heishuihe national wetland park is typical karst landform river wetland in southwest Guangxi,with complete ecosystem and special habitat.In order to provide references for resource protection of Heishuihe wetland park,based on background and monitoring survey data of Heishuihe wetland park from 2017 to 2018,diversities of vascular plants,types of wetland plant communities and wild seed plant flora were ana-lyzed.Results showed that there were abundant vascular plants with 492 species belonging to 122 families and 375 genera,including wild vascular plants 477 species belonging to 119 families and 365 genera,and wild wet-land vascular plants 101 species belonging to 43 families and 83 genera.Among wild seed plants,majorities of families were few families and momo families,accounting for 72.17%of total family of wild seed plants.Majori-ties of genera were mono genera,accounting for 78.98%of total genus of wild seed plants.Proportions of areas of hygrophyte plant communities and aquatic plant communities accounting for total area of wetland vegetation were 67.37%and 32.63%respectively,with hygrophyte plant communities as dominant.R/T values of families and genera of wild seed plant flora were 4.45 and 4.24 respectively,indicating that plant flora had obvious tropi-cal ingredients and characteristics.
