摘要
2004年4月-5月,利用样带法对达赉湖自然保护区5种主要生境类型中冬春季鸟类生物多样性进行了调查, 利用Shannon-Wiener指数和Smith相关性系数分析了这5种生境类型中冬春季鸟类的生物多样性、区系、鸟类的群落组成、群落间的相似性和均匀度。结果表明,古北界鸟类是组成达赉湖鸟类群落的主体(约占冬春季鸟类的86%);芦苇湿地的鸟类多样性接近于芦苇甸的2倍:芦苇湿地鸟类群落的物种多样性最高(Shannon-Wiener指数为1.3001),而芦苇甸中鸟类群落的物种多样性最低(Shannon-Wiener指数为0.6629);芦苇湿地和芦苇甸两鸟类群落组成的相关性指数仅为0.038;从具有共同物种的多少考虑,典型草原和芨芨草原鸟类群落之间的关联较大。
From April to May in 2004, the bird diversity of the winter and the spring was investiaged in the five main habitats of Dalai lake natural reserve with sample belt. The composition, fauna, similarity of communities, evenness indices and communities biodiversity were analyzed using the Shannon-Wiener index and Smith correlation index. The results shows that most species are from the Palaearctic Realm （about 86%）, the bird diversity of reed wetland is proved to be maximum （Shannon-Wiener index = 1.300 1 ）, and reed meadow to be minimum （Shannon-Wiener index = 0.662 9）. The correlation index of community composition is only 0.038 between the reed wetland and the reed meadow. The survey also reveals the simliar bird diversity between shining speargrass grassland and that of typical prairie.
