摘要
中华秋沙鸭是一种分布区域狭窄、数量稀少的濒危鸟类,在我国属于一级重点保护动物,国际上视其为易危物种。江西省境内一直是中华秋沙鸭的主要越冬栖息地。为了解中华秋沙鸭在我国的越冬地和生境情况以及中华秋沙鸭的种群数量变化,合理保护现有物种,对其在江西省境内的越冬地进行调查与比较。调查发现,中华秋沙鸭越冬地主要在江西的弋阳、浮梁、修水、婺源等地,其越冬栖息地特征明显,且具有明显共性。
Mergus squamatus was a kind of narrowly distributed, rare and endangered wild bird, which was a protected animal of class A and was a kind of international easily endangered species. Jiangxi province was a major wintering habitat of M. squarnatus. In order to better understand its wintering habitat, living condition and population quantity in China, we investigated and compared its overwintering habitats in Jiangxi province so as to rationally protect existing population nowadays. The investigation results indicated that M. squamatus mainly distributed in habitats such as Yiyang, Fuliang, Xiushui, Wuyuan, and the characteristic of their habitats was distinctive and had obvious similarity.
