中国珍稀濒危物种——朱鹮

朱曾广泛分布于中国、日本、朝鲜半岛和俄罗斯的远东地区。其它国家的朱先后灭绝,目前只栖息于我国,为我国所特有,是我国四大国宝之一,当今世界极濒危级鸟类。1981年朱在陕西洋县重新被发现时其种群数量只有7只,经20余年的保护,目前我国朱的总数已达到700余只,人工繁殖也取得巨大成功。笔者想通过本文唤起人们对生活在西部边远地区的我国珍稀鸟类———朱的关注与保护。

Rare and Endangered Nipponia nippon in China

Crested ibis,Nipponia nippon,as an endangered bird in the world,has been said to be one of the four natural treasures in China.Historically,crested ibis was once distributed to some countries such as China,Japan,Korean Peninsular and the Far East in Russia.Crested ibis population in Japan,Korea and Russia was extinct during 20 century.Now crested ibis exists only in China.The rediscovery of the crested ibis was in 1981 in Yangxian County,Shaanxi Province,and there were 7 crested ibises in total.With great efforts,the population was protected and nourished.Now there are more than 700 birds in the wild and in captivity after more than 20 years,and significant achievements have been made in artificial reproduction of crested ibis.In this paper,the authors call for intense concentration on protection of Nipponia nippon inhabited in China.
