A Survey of Vegetation of Benniu Airport and Adjacent Area,With an Assessment of Bird Fit Index

对常州奔牛机场内部及周边地区的植被进行了详细调查,在此基础上从植物对鸟类活动的贡献的大小出发,就植物在群落中的地位、高度、生活型及提供鸟类食物能力4个方面对机场内分布植物的鸟类适宜指数进行评估.结果显示机场内鸟类适宜指数最高的植物共有7种,它们对鸟类有着强烈的吸引作用,应清除机场内的这些植物;另有19种植物适宜指数较高,应在机场内严格控制其高度和种群大小.

On the basis of substantial vegetation investigation of Changzhou Benniu airport and its＇ adjacent area, the Bird Fit Index （BFI） were evaluated on all the plant species. The BFI mainly explorer the degrees that the plant attracted birds, with Emphasis on four factors ： （ 1 ） The species＇ status in the community, （2） Height, （3） Living form, （4） The contribution to bird＇ s feeding. Totally, we found seven species with the highest BFI, which indicated that they should be removed as soon as possible. As the same time, other ninteen species, which showed relatively high BFI, should be controlled strictly on the plant height and their population size.
