摘要
为了解天津滨海国际机场地被昆虫的多样性特征从而有效防控该地区的鸟类撞机事件,分别于2014年和2015年的4—9月份,对该地区3个样地的地被昆虫进行了连续调查,并利用昆虫群落优势度、丰富度、均匀度和多样性等指标对不同区域的地被昆虫进行测度和分析.结果表明:(1)在天津滨海国际机场这一特定生境共采集到9目22科的昆虫种群,其中鳞翅目、鞘翅目和蜻蜓目等为优势类群;(2)在紧邻机场边界且靠近农田与村庄的六号泵站附近和有丰富水源的西跑道南航向地被区,昆虫多样性指数高于周围有建筑群和垃圾堆放的七号泵站附近地被区,七号泵站附近地被区的物种丰富度最高,西跑道南航向地被区次之,六号泵站附近地被区最低;(3)各生境区域昆虫群落的均匀度指数与多样性指数季节变化趋势相同,优势度指数特征排列顺序为:六号泵站附近地被区>七号泵站附近地被区>西跑道南航向地被区;(4)3种生境中的昆虫相似性系数都较高,反映出各生境类型中昆虫栖息地空间的异质性较小.
To learn the insect diversity to prevent the birdstrike in the grassland of Tianjin Binhai International Airport, the continual and systematic investigations on insect community in the grassland of this area were conducted from April to September in 2014 and 2015. Meanwhile, a series of index, including species dominance, richness, evenness and diversity were adopted to investigate and analyze the insects in three sample plots in this area. The results showed that ： （ 1 ） The insects captured in Tianjin Binhai International Airport belonged to 22 families in 9 orders, among which Lepidoptera, Coleoptera and Odonata were the dominant taxa; （2） The insect diversity index of No. 6 pump station grassland, which was near to farmland and countryside, and south course of west runway grassland close to water area was higher than that of No.7 pump station grassland surrounded by buildings and garbage. The richness index of No.7 pump station grassland was the highest, followed by that of south course of west runway grassland, and that of No.6 pump station grassland was the lowest ; （3） The temporal dynamics of community evenness and community diversity in different habitats were similar. The dominance had the order of No. 6 pump station grassland〉No.7 pump station grassland〉south course of west runway grass- land ; （4） The similarity coefficient in different habitats was at similar or extremely similar levels, which indicated that the habitats of insect had smaller spatial heterogeneity amony different habitat types.
