摘　　要：[目的]了解深圳坝光银叶树湿地园植物资源本底现状,为该园区植物资源的保护、修复与合理利用提供依据。[方法]采用野外全域调查和室内标本鉴定相结合的方法,对深圳坝光银叶树湿地园内植物群落进行鉴定与统计。[结果]共记录植物113科353属433种,优势科属为禾本科、菊科和大戟科,野生植物和园林植物分别占园区植物总种数的58.20%和32.10%。从生活型组成来看,园区植物主要由草本植物、乔木植物和灌木植物组成,分别占总种数的41.11%、29.79%和21.25%。园区特色植物包括树龄200 a以上的古银叶树33棵、红树植物16种和国家二级重点保护植物4种。园区有外来入侵植物21种。[结论]坝光银叶树湿地园植物物种组成丰富,优势科属植物集中,特色植物突出,具有重要保护价值。园区外来植物入侵风险较高但危害程度一般,需加强监管。[Purpose]The current situation of plant resources in Baguang Heritiera littoralis Wetland Park,Shenzhen was investigated to provide basis for the protection,restoration and rational utilization of plant resources in the park.[Method]Global field survey combined with laboratory specimen identification were conducted to identify and statistically analyze the plant community in the Baguang Heritiera littoralis Wetland Park.[Result]A total of 433 species of plants belonging to 353 genera and 113 families were recorded,with the dominant family being Gramineae,Asteraceae and Euphorbiaceae.Wild plants and garden plants accounted for 58.20% and 32.10% of the total plant species,respectively.From the perspective of life form,herbs,arborous plants and shrubs were dominant plants,representing 41.11%,29.79% and 21.25% of the total species,respectively.Thirty-three ancient H.littoralis trees which were over 200 years old,16 species of mangrove plants,and 4 species of secondary key protected plants made up the most characteristic plants in the park.In addition,21 species of invasive plants were recorded.[Conclusion]Baguang Heritiera littoralis Wetland Park has relatively abundant species composition with prominent dominant families and characteristic plants,implying its important conservation value.The invasive plants in the park are at high-risk levels but with lower hazard,which require strengthened supervision and control.
