摘要
在2004—2007年每年的7—9月4次实地调查及参考相关资料基础上,分析了山东荣成大天鹅自然保护区湿地植物区系的特征。区系中有单细胞浮游藻类59属192种,底栖多细胞大型海藻58属74种,维管束植物55科134属194种。区系中的单细胞浮游藻类包括近岸广布种116种、近岸暖水种31种、近岸温带种26种;维管束植物被划分为6大生态类群,包括盐生植物24种、水生植物22种、湿生植物35种、中生植物103种、旱生植物6种、沙生植物4种,保护区内湿地植被的建群种、优势种均为水生植物、湿生植物或盐生植物,反映了湿地植被的隐域性;维管束植物按照生活型划分,有20种高位芽植物、4种地上芽植物、54种地面芽植物、48种地下芽植物和68种1年生植物,其中地面芽植物、地下芽植物占区系植物总种数的比例较高,占52.58%,反映冷湿气候和局部低洼积水环境对区系的形成起较重要作用。维管束植物属有14个地理分布区类型,包括世界分布属42属、温带分布属55属、热带分布属30属、古地中海属2属、东亚分布属4属、中国特有分布属1属,其中世界分布属和温带分布属分别占区系维管束植物总属数的比例较高,分别为31.34%和41.04%,反映了湿地植被的隐域性和冷湿气候对湿地植被发育、分布的影响。
Based on four field investigations in July - September from 2004 to 2007 and reterence data, the characteristics of wetland flora in whooper swan nature reserve in Rongcheng of Shandong were analyzed. There were 192 species and 59 genera of single-celled phytoplankton, 74 species and 58 genera of large benthic multicellular marine algae, and 194 species, 134 genera and 55 families of vascular plant. The single-celled phytoplankton included 116 inshore wide distribution species, 31 inshore warm-water species and 26 inshore temperate species, and the vascular plants were of 6 ecological groups, i. e. , halophtes （24 species）, hydrophtes （22 species）, amphiphytes （35 species）, mesophytes （103 species）, zerophytes （6 species）, and psammons （4 species）. Halophtes, hydrophtes, and amphiphytes were the edificators and dominants, reflecting the azonal feature of the wetland vegetations. The vascular plants were divided into 5 life-forms, including 20 phaenerophytes, 4 chamaephytes, 54 hemicryptophytes, 48 geophytes and 68 therophytes, among which, hemicryptophytes and geophytes accounted for 52.58%, reflecting the relatively important function of cold and wet climate and local water-accumulated bottomland environment on the vascular flora formation. The 134 genera of vascular plants had 14 areal-types, including 42 cosmopolitans, 55 temperate types, 30 tropic types, 2 Mediterranean-types, 2 East Asia types, and 1 endemic species. The cosmopolitan and temperate type accounted for 31.34% and 41.04% of all the genera, respectively, revealing the azonal feature of the wetland vegetations and the influences of cold and wet climate on the formation and distribution of the vegetations.
