黑龙江省小北湖鸟类群落分布分析

Study on Distribution of Birds Community in Xiaobei Lake of Heilongjiang Province

利用Shannon-Weiver信息论公式与Peilou的均匀度公式,1998年3～5月、1999年3～5月间, 对宁安小北湖5个不同生境鸟类群落的多样性指数及均匀度的分析。结果表明,虽然在次生阔叶林、草甸沼泽的鸟类具有较大的多样性,但是在分布的均匀度上差异不大。在湖泊、沼泽与森林相互交错的地域,是鸟类最佳的生存地带,而湖泊、沼泽周围森林的完好程度直接关系到鸟类的生存。

We utilized the formula of Shannon-Weiver information theory and Peilou抯 uniformity, studied diversity indexes and uniformity of birds community which lived in different environments in Xiaobei lake from March to May in 1998 and 1999. The results showed that great diversities lied in the residence here the birds living, the birds communities which lived in second broadleaf forest, swamp and meadow and significant diversity and few difference in uniformity of distribution. The lake, swamp and forest interlace were the best environment where the birds lived, and integrated degree of forest which lied on lake and swamp directly affect survival of the birds.
