摘 要 ：黄斑苇鳽是夏候鸟,每年5—8月在上海奉贤县沿海新海塘繁殖。本文对其繁殖期种群分布型等进行研究,并用Poisson法测定。研究表明该种鸟巢的空间分布属于集群型。集群分布之巢占64.04％;每群6.081.76只,结构较为松散。其巢的空间生态位是芦苇层次中的中层。文中还讨论了生态位层次之间的关系以及生态位分离、种群密度和种群数量变动等问题。

Abstract:The bittern (I xobrychus sinensis Gmelin), a migrant bird, breeds on Xinhai reed bed Fengxian, shanghai, from May to August every year. Durinng the breeding period the population density is 11.4 pairs/ha. The highest is in the irrigated reed bed with 31.1813.74 pairs/ha. The fluctu-sation in population number is remarked during the breeding period.Analyses of clumped distribution with a Poisson method show S2/X = 3.49>1, p<0.01. The nest distribution belongs to the clumped patterns.During the reproduction ...
