深圳华侨城湿地物种多样性及其保护研究 总被引:2,自引:2,他引:0
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。 相似文献

Annotation on Mangrove Plants 总被引:1,自引:0,他引:1
This paper reviews and discusses the technical terms and definition of mangrove and lnangal, as well as mangrove plant. The word mangrove has been used to refer either to the constituent plant of tropical and subtropical intertidal community or to the community itself but this usage makes mote confusion. Being leaved mangrove in the more limited sense for the constituent plant species, mangal was proposed by MacNae (1968) as a term for mangrove community, which has been universally applied to most previous studies and should be adopted now. Mangrove should be therefore defined as a tropical and subtropical tree restricted to intertidal zones, which possesses some morphological specializion and physiological mechanism adapted to its habitat, and mangal as a tropical and subtropical forest community restricted to marine intertidal zones and periodically inundeated by the tides, A new term “consortive plant” is proposed here for herb. liana, epiphyte or parasite, which is restricted in the strict mangrove habitat. 相似文献

Wetland ecosystem in the Shenzhen Bay is one of the internationally important ecosystems in South China Region. Its core, with the Mai Po Mangrove Nature Reserve in Hong Kong on the one side and the Futian Mangrove Nature Reserve in Shenzhen on the other side, provides habitats for many rare and endangered wild birds, especially for migratory birds[1, 2]. With the economic development in Hong Kong and Shenzhen, a large mount of silt and untreated waste water are poured into the Shenzhe… 相似文献
