黄河三角洲大鸨越冬状况及保护对策

The wintering status and protective measures of the Great Bustard in the Yellow River Delta

黄河三角洲是大鸨的一个重要越冬栖息地,调查结果显示,从1997年到2006年在黄河三角洲越冬的大鸨数量总体上在减少,甚至在某一年度(2001)仅观察到8只大鸨。草地开垦、农田耕作类型改变、农药使用及人为活动干扰可能是造成黄河三角洲大鸨越冬数量减少的主要原因。在未来保护行动中我们应加强大鸨数量动态监测和越冬栖息地选择研究的开展,实施越冬地保护措施,吸引社区参与管理,保护大鸨及其生存环境。

The Yellow River Delta is one of the important wintering sites of the Great Bustard. The findings from 1997 to 2006 in the Yellow River Delta showed that the wintering numbers of the Great Bustard were in general declining, especially; only eight Great Bustard were observed in 2001. Grassland reclamation, change of agricultural farming types, use of pesticides and human activities in the Yellow River Delta may be responsible for the decrease of Great Bustard in the Yellow River Delta. In the future, we should strengthen the dynamic monitoring of the number of Great Bustard and to the study of their wintering habitats selection, the protection of Great Bustards and their habitats.
