摘　　要：深圳华侨城湿地位于珠江口深圳湾北岸,通过箱涵与深圳湾海水相通,总面积69万m2,水域面积约50万m2,是深圳湾湿地生态系统的重要组成部分。对华侨城湿地植被、鸟类、底栖生物、浮游生物的多样性进行了调查,结果表明:华侨城湿地共有植物60科162种,其中真红树植物5科6属7种,半红树植物3科4属5种,外来入侵植物27种;鸟类共有12目36科101种,约占深圳湾鸟类总种数的50%,其中国家Ⅱ级重点保护野生鸟类6种;共鉴定出藻类5门11属14种;浮游动物25种。华侨城湿地面临严重的生态危机,主要包括入侵植物大面积分布、物种单一,鸟类、底栖生物类等生物多样性与福田红树林保护区及凤塘河口相比较低,并据此提出了相应的保护建议。The wetland of Overseas Chinese Town (OCT) is located in the Pearl River estuary, Shenzhen. Its total area is about 690,000 m2, including 500,000 m2 of water areas. It is an important component of the wetland ecosystem in Shenzhen Bay. In this paper, we study and analyze biodiversity of OCT wetland of the native plants, alien plants and vegetation types, birds, benthic, plankton, etc. The results showed as following:The total number of plant species is 162 belonging to 60 families, including 7 species of true mangrove belonging to 6 genera and 5 families, and 5 species of semi-mangrove belonging to 4 genera and 3 families; The number of bird species is 101 belonging to 36 families, accounting for 50% of the total number of birds in Shenzhen Bay, including 6 wild animal species of Class II priority for protection;A Total of 14 algae was identified, belonging to 11 genera; 5 species of zooplankton were identified. The results indicated that the wetland is facing a serious ecological crisis, including the large area spread of invasive plants, simplification of species composition. The biodiversity of both birds and benthic organisms was lower than that of Futian Mangrove Nature Reserve and Feng Tong estuary Wetland. It needs to take certain protective measures to strengthen the integrated management.
