扎龙自然保护区常见水禽分布类型及群落多样性

Distribution Type and Community Diversity of Common Waterfowls in Zhalong Natural Reserve

对扎龙自然保护区常见的水禽进行了调查,其结果表明繁殖鸟类多为集群分布,在两个主要巢区内,草鹭、苍鹭为优势种,白琵鹭、白（睘鸟）、鸬鹚、骨顶鸡等为常见种,丹顶鹤、白枕鹤为稀有种,两个巢区的多样性指数分别为0.935和0.813.

This paper was carried out in 1989,we had a investigation to common waterfowls in Zhalong Reserve. The result showed that the breeding birds clumped distribution in their reproductive aeras. In two main reproductive aeras,purple heron(Ardea purpurea)and grey heron (A. cinerea) were dominant species, spoonbill (Platalea leucorodia). Oriental ibis(Threskioruis melanocephalus),great cormorant (Phalacrocorax cabro) and coot (Fulica atra) were common species,japanese crane (Grus japonensis) and white-naped crane(G vipio) were rare species. The diversity index of two main home ranges were 0.935 and 0.813.
