摘　　要：几何形态计量学着重研究生物形态的拓扑结构信息,不受昆虫标本大小和形状等因素的影响.本文提出利用几何形态计量学中的相对扭曲分析来实现昆虫分类鉴定的研究,做为方法论的探索,本文以鳞翅目夜蛾科6种蛾类昆虫的翅脉图像样本为试验材料.首先利用软件TpsDig2获取6种蛾180个右前翅翅脉样本的标记点,再运用软件TpsSuper对其进行普氏叠加分析,消除非形状因素等多余的信息,最后利用软件TpsRelw进行相对扭曲分析,通过分析得到的相对扭曲图像可以使昆虫的分类实现二维可视化,因此可以更直观地做出其种类的鉴定.研究结果表明本文为蛾类昆虫的可视化鉴定提供了一种可行的方法,对于昆虫分类鉴定的形态学测量数据可视化具有重要意义.Geometric morphometric focuses on topology information of biological morphol- ogy, which is nothing to do with the size and shape factors of insect specimen. As exploration of methodology, relative warp analysis was used to realize the visualization of insect classification and discrimination in this paper. Vein images from six kinds of moths which belonged to Noctuidae, Lepidopter were used as material. On the first step, landmarks were extracted from right front wings of six kinds of moths by using the software TpsDig2. On the second step, to eliminate the superfluous information resulted from non-shape factors, the software TpsSuper was applied to accomplish the procrustes superimposition analysis to coordinates of landmarks. On the last step, the software TpsRelw was used to carry out relative warps analysis, which provided images to achieve the two-dimension visualization of insect classification and discrimination more intuitively. The results indicated that a sort of feasible method was put forward to achieve visualization of insect classification and discrimination in this paper, which was highly important for visualization application of morphological measurement data used for insect classification and discrimination.
