深圳湾湿地的黑脸琵鹭及其保护

深圳湾湿地是世界淑危鸟类－黑脸琵鹭最重要的越冬栖息地之一。1999－2000年在此越冬的脸琵鹭数量178只，约占世界总数量的25％。近十年来深圳湾湿地黑脸琵鹭的数量逐年增加，主要原因可能是由于其它湿地环境恶化而使黑脸琵鹭集中到深圳湾，这种情况对黑脸琵鹭的生存和发展是不利的。深圳湾湿地生态环境存在诸多问题，使该湿地生态系统环境质量不断下降，因此，提出了保护深圳湾湿地生态环境的若干建议。

The conservation of Black-faced Spoonbill in Shenzhen Bay (Deep Bay)

Shenzhen Bay is one of the most important wintering ground of the endangered Black-faced Spoonbill. In the winter of 1999 -2000, 178 Black-faced Spoonbill (25% of the world population of the species) wintered in Shenzhen Bay. Over the years, the number of wintering Black-faced Spoonbill of Shenzhen Bay has gradually increased. One possible factor for such an increase is the deterioration of surrounding wetland habitats, which forces the Black-faced Spoonbill to aggregate at Shenzhen Bay. The rapid shrinking of its essential living environment will jeopardize the long-term survival of the species. In view of the threats and problems facing the Shenzhen Bay ecosystem, the authors provide suggestions for the protection of the wetland environment.
