| 摘 要： | 运用因子分析方法,以斑小蜻属Nannophiopsis、灰蜻属Orthetrum和黄蜻属Pantala(蜻蜓目蜻科)成虫腹部、后翅、后翅痣、上肛附器、内肛附器和第10腹节的长度作为数值变量进行分析。分析结果表明:6项数量性状可通过分别代表体型、后翅长和内肛附器长的三个公因子反映,利用因子得分散点图可较好地对3属的成虫进行区分。 |

| Abstract: | A factor analysis of six quantitative variables, which were the length of abdomen, hindwing, pterostigma of hindwing, superior appendage, inferior appendage and the 10th abdomen of three genera, Nannophiopsis, orthetrum and pantala (odonate, libellulidae), was carried out in this paper. The results shoed that the three extracted fators containing information from the body size, the length of hindwing and the inferior appendage could well represent the six quantitative variables. And a good result of classification from the three genera was also achieved by the scatterplot based on the factor score. |
