南宁市郊三种人工林型夏季鸟类多样性初步分析

Summer bird diversity in three different artificial forest in suburbs of Nanning

研究不同人工林型中的鸟类群落可以了解其生态效益。于2007年6~8月采用样带法对南宁市郊的三种人工林中的鸟类种类和数量进行了统计,共记录到鸟类3目15科26种。经分析所得鸟类多样性指数,湿地松林的最高,为1.0350;其次为马尾松林,为1.0153;巨尾桉林的最低,仅为0.5048。同时计算了G-F指数,其中马尾松林和湿地松林的值分别为0.1539和0.1604,巨尾桉林为0。从马尾松林和湿地松林的相似性对比中可以看出这两类林型中鸟类群落相似性比较高,巨尾桉林与其他两种林型相似性差异较大。鸟类多样性与人工林异质性和林龄有关。

It could get the ecological benefits while doing researches in bird communities in different artificial forests.Survey on bird species and numbers was counted by line sampling method in three different artificial forests in the suburbs of Nanning from June to August 2007.Twenty six species were recorded,belonging to 15 families and 3 orders.The results showed that the bird diversity index in Pinus elliottii forest was 1.0350,in Eucalyptus grandis forest was 0.5048,in Pinus massoniana forest was 1.0153.The p...
