摘　　要：以《珠海淇澳-担杆岛省级自然保护区科学考察报告》的有关材料为依据,对珠海淇澳-担杆岛省级自然保护区的维管植物类群及分布区系进行研究。结果表明:①该保护区共记录维管植物171科608属984种(含野生维管植物152科505属819种),约占广东省维管植物总数7320种的13.6%;遗传多样性比较脆弱,表现在单种科和寡种科、单属科及单种属所占比例较大;②因该保护区地处沿海潮间带湿地滩涂和小海岛立地,植物多样性天赋不足,故与广东阳春百涌省级自然保护区相比,物种丰富度各有千秋,但后者的野生物种更为丰富;与广东全省相比,各类植物数量所占比例均较少,但与同等级自然保护区相比,仍处于较高水平;③保护区的维管植物区系以热带分布类型为主,与其地处南亚热带气候区大致吻合;④保护区的植物群落恢复与重建范例可供国内外自然保护区植物多样性建设借鉴。Based on the Scientific Investigation Report of the Qi'ao-Dangan Island Provincial Nature Reserve in Zhuhai,this study found that:①the reserve recorded a total of 984 species of vascular plants in 608 genera of 171 families(including 819 species of wild vascular plants in 505 genera of 152 families),accounting for approximately 13.6%of the total 7320 species of vascular plants in Guangdong Province;Genetic diversity is relatively fragile,The proportion of single-species family,few-species family,single-genus family and single-species genus is large;②The As the nature reserve is located in the coastal intertidal wetland mudflat and site condition of small island,the lack of natural plant diversity,so compared with Guangdong Yangchun Baichong Provincial Nature Reserve,the species richness is different.But wild species is more abundant in the latter than in the former;Compared with Guangdong Province,the proportion of various types of plants is relatively small,but it is still at a relatively high level compared to nature reserves of the same level;③The vascular plant flora of the protected area is mainly tropical,which is roughly consistent with its location in the South Asian tropical climate zone;④The restoration and reconstruction of plant communities in protected areas can serve as a reference for the construction of plant diversity in nature reserves both domestically and internationally.
