摘要
通过对位于河北省北部的塞罕坝国家森林公园的森林节肢动物群落进行调查,发现随林分类型不同节肢动物群落存在差异。混交林中节肢动物的物种数要多于纯林,且物种的个体数也较纯林分布的均匀;纯林则经常会存在一个优势种,其数量有时可达到总个体数的70%之多。分别运用物种多样性、物种均匀度、物种优势度等指数的计算公式分析各样地所的数据,发现混交林的物种多样性指数和物种均匀度指数要高于纯林,而对物种优势度进行方差分析则发现混交林和纯林优势度指数并没有显著差异。
By the study on diversity of arthropod community in the forests of the National Forest Park of Saihanba, which is located in the north of Hebei province,it is discovered that there are differences of arthropod community in different style of forests. In the mixed forest, where the species is more than the pure forest, the distributing of the number of species is proportion than pure fores＇t too;And the pure forest always has a dominant species. Use the formulas of species diversity index and species evenness index to analysis the data what is come from all the experiment we have done, and find that in the mixed forest the species diversity index and species evenness index is high than in pure forest.
