中国大鲵资源现状及保护对策

摘要

The amount of Chinese giant salamander A.davidianus had been sharply declined from 1980s to 1990s,and its habitat is getting smaller,appearing a characteristic of scattered and dotted distribution.In order to provide basis for its protection and utilization,the geographic distribution, population,reasons of decline,and status of artificial breeding were analyzed.The targeted ecological protection countermeasures were proposed in the article according to its development characters in recent years.%20世纪80—90年代，大鲵资源锐减，栖息地越来越小，呈现零星破碎化和点状分布的特点。为中国大鲵资源的保护和开发利用提供参考依据，分析了野生大鲵的地理分布、种群数量、资源衰退的原因和大鲵人工驯养现状，并根据大鲵资源近年来的发展特点，提出了针对性的生态保护对策。
