高黎贡山地区雉类多样性及其保护

根据高黎贡山地形和气候变化,将其分为南、中、北三段。通过查阅文献、访谈和野外调查,在该地区共记录到21种雉类。分布在海拔2500m以上的仅有9种,占45%;在海拔2500m以下的地域分布有雉类17种,占85%。北段有雉类13种,中段有11种,南段有12种。其中北、中、南段均有分布的仅有3种,北段和中段共有种为9种,中段和南段共有种为5种,北段和南段共有种也是5种。结果表明雉类多样性随海拔升高而降低,北段高于南段。生境破坏与狩猎是该区雉类生存的主要威胁因子。加强管理,恢复和建立生境走廊,加强宣传教育和执法力度以及开展观鸟旅游,可使该区雉类得到更好的保护。

Pheasant Diversity and Conservation in the Mt. Gaoligongshan Region

Mt. Gaoligongshan is located in northwest Yunnan province and is approximately 600 kilometres from the north to the south. It is higher in altitude in the north and lower in the south with about 4900 vertical metres difference in this region. According to its topography and climate,Mt. Gaoligongshan could be divided into southern,central and northern parts. Twenty-one pheasant species in this region were recorded using field investigation,interviews and literature checking. The pheasant diversity decreased with the rise in elevation,and also from the south to the north. There were only nine species above 2 500 m altitude and 12 species under 2 500 m. There were 13,11 and 12 species respectively in the north,central and south areas. Habitat destruction and hunting are the main threats to the survival of pheasants in this region. For better protection for the pheasants in this region,we suggest strengthening habitat management and restoration,establishing habitat corridors,strengthening public environmental education and developing bird-watching tourism.
