| 摘 要： | 为深入了解影响甘草田节肢动物群落多样性的因子,对宁夏人工种植甘草田节肢动物群落物种数、个体数、多样性指数、丰富度指数、均匀性指数及优势集中性指数等主要特征值之间的关系做了主成分分析和通径分析.结果显示:甘草田节肢动物群落多样性与节肢动物群落均匀性关系最为密切,因此,要提高甘草田节肢动物群落多样性就要通过控制优势种群的增长,使物种分布相对均匀.

| Abstract: | In orde to study the arthropod community, the species richness, individuals, diversity index, species richness index, evenness index and community concentration index of licorice farmland were calculated and their relationships were studied using the methods of main component analysis and path analysis. The results showed that the diversity had a close relation with evenness of arthropod community. Thus, the diversity of arthropod community could be increased by controlling the growth of dominant species. |
