浙江舟山群岛沙滩植被的地理成分及典型植物群落特征
Geographic composition of beach vegetation and characteristics of typical plant communities in Zhoushan Archipelago,Zhejiang Province
摘要
Abstract
[Objective]As a non-zonal azonal vegetation,island beach vegetation plays a significant role in beach protection,species conservation,and biodiversity maintenance.This study aimed to elucidate the geographical composition and characteristics of typical plant communities in island beach vegetation.[Method]The vegetation status of 11 typical beaches across 9 islands in the Zhoushan Archipelago was investigated using the Braun-Blanquet approach.The geographical composition of beach vegetation was analyzed,and the composition and structural fea-tures of typical plant communities were examined based on quadrat surveys of 33 plots(1 m×1 m).[Result]1)A total of 74 plant species,belonging to 34 families and 71 genera,were recorded on the beaches of the Zhoushan Ar-chipelago.Herbaceous plants accounted for 78.37%,with 74.29%of families represented by a single species.Fami-lies with higher species richness included Asteraceae,Poaceae,Chenopodiaceae,and Fabaceae.2)The geographical composition of plant families and genera exhibited prominent cosmopolitan(76.47%)and pantropical(45.72%)dis-tributions.3)The vegetation types included terrestrial herbosa,halophytic herbosa,and psammophytic herbosa,pre-dominantly in early succession stages with graminoids as the dominant life form.4)Typical plant communities com-prised Cynodon dactylon,Calystegia soldanella-Carex kobomugi,Vitex trifolia,Carex kobomugi,Oenothera drum-mondii-Calystegia soldanella,Fimbristylis sericea,Lathyrus japonicus,Glehnia littoralis,and Conyza canaden-sis-Erigeron bonariensis communities.[Conclusion]Beach vegetation in the Zhoushan Archipelago has simple geographical components but diverse plant communities,serving as an excellent natural model for beach vegetation restoration in eastern Zhejiang islands.However,given severe coastal erosion and anthropogenic impacts threatening beach ecosystems,urgent conservation and restoration efforts are required.关键词
