庐山鸟类多样性及季节动态分析

Bird Diversity and Seasonality in Lushan

2010年1月～2011年1月,采取样线法,共选取18条样线对庐山鸟类的多样性进行调查,共记录鸟类94种,隶属14目36科。其中留鸟60种,夏候鸟15种,冬候鸟16种,旅鸟3种。对不同季节的鸟类群落特征进行比较分析,从Shannon-Wiener指数看出,秋季多样性最高,为3.49;夏季次之,为3.44;冬季为3.40;春季为3.17。比较均匀性指数发现,秋季的均匀度最高,为0.51;冬季次之,为0.49,与前者仅有0.02的差距,可见二者丰富度差距很小;春季为0.41;夏季最低,仅有0.37,比较各季度的差距发现,最高的季度和最低的季度之间的差距为0.14。说明庐山鸟类的均匀度相差不大,庐山的鸟类群落均匀性在时间上无明显波动,相对稳定。
