中文摘要:
      渤海是斑海豹在我国唯一的繁殖地。研究结果表明,半个多世纪以来,渤海的斑海豹数量减少了 80%。尽管我国20 世纪末已将斑海豹列为国家 II 级保护野生动物,采取了建立自然保护区等一系列措施,但在海洋生态环境持续恶化的情况下,其数量仍不断减少。近年来,随着海洋环境的改善,斑海豹的数量有了明显回升。本文从海冰面积、鱼类资源以及水质污染等方面分析了渤海海洋环境的状况,探讨了斑海豹数量变化的原因。本文研究可为我国有关部门在制定渤海环境保护政策时提供参考。
英文摘要:
      The Bohai Sea is known as the only breeding ground for spotted seals along the coast of China. Many studies indicate that the population of seals has experienced a decrease of 80% as a consequence of sharp environment deterioration in the Bohai Sea over the past 50 years. Although the Chinese government has classified it as national II class protected wildlife and created nature reserves to protect the spotted seals since the end of the 20th century, the number of spotted seals has been decreasing continually with the deteriorating of marine environment. With the improvement of the marine environment in recent years, the number of spotted seals in the Bohai Sea has rebounded significantly. This paper analyzed the conditions of marine environment in the Bohai Sea from the changing of the sea ice areas, fish resources amount, and water pollution, researched the adaptability characteristics of spotted seals in marine environment, and discussed the reasons for the change in the number of spotted seals. It can provide a reference for environmental policy making of the Bohai Sea.
