摘要(Abstract):
昆虫多样性可以反映出不同的地理和自然环境的破坏程度,为研究重金属污染地区不同恢复程度下自然环境健康状况,对葫芦岛地区3个重金属污染区域的30个样方进行了昆虫多样性调查,共获得166头昆虫,隶属于9目21科,在3个样地中均有直翅目、鳞翅目、鞘翅目、膜翅目、半翅目昆虫分布。应用Simpson优势集中性指数、Shannon-Wiener物种多样性指数H′及均匀性指数J对保护区内昆虫多样性进行分析,结果显示,植被恢复越好的地区,其昆虫类群多样性和生物多样性指数越高。
Insect diversity can reflect the destruction degrees of different geography and natural environment. In order to study the health status of natural environment under different restoration degrees in heavy metal polluted areas, 30 plots from 3 heavy metal polluted areas in Huludao area were investigated for insect diversity. A total of 166 insects were obtained, belonging to 9 orders and 21 families. Orthoptera、 Lepidoptera、 Coleoptera、 Hymenoptera and Hemiptera were found in the three sampled areas. The Simpson dominance concentration index, Shannon-Wiener species diversity index H′, and Homogeneity index J were applied to analyze the insect diversity in the protected area.The results showed that the better the vegetation restoration was, the higher the insect group diversity and biodiversity index were.
