选择秦岭南北５地中华稻蝗（Ｏｘｙａ ｃｈｉｎｅｎｓｉｓＴｈｕｎｂｅｒｇ） 的每地雌雄各１２ 个个体的１３个形态特征进行测量， 取每一地同一性别不同个体的平均值分别形成雌雄的原始数据矩阵。用自然对数的绝对值对雌雄原始数据矩阵分别进行标准化后， 用ＰＣＴ距离系数和离差平方和法进行聚类。用欧氏距离系数和单链法、全链法等聚类方法进行验证。结果表明： 汉中和安康一线沿秦岭山脉南麓汉江两岸的中华稻蝗距离较近， 应为一个地理宗或居群； 秦岭山脉北麓的眉县至长安一线的中华稻蝗距离较近， 应为一个地理宗或居群； 黄土高原另一侧的延安地区的中华稻蝗应为一个地理宗或居群。
Thirteen morphological traits of 12 individuals from each locust in Oxya chinensis Dunhberg were screened, and the mean of different individuals of each sex was used to form the matrices of the male and female, respectively. After normalizing the males and females’ original data matrices respectively with the absolute value of natural logarithms, the clustering was carried out by PCT distance coefficient and variance square method. Euclidean distance coefficient and single-chain method, full-chain method and other clustering methods for verification. The results showed that the Hanzhong and Ankang line should be a geographic or herpetitive along the Hanjiang River at the south foot of the Qinling Mountains and near the Qinling Mountains. As a geographic zong or population; on the other side of the Loess Plateau Yan’an area of Chinese locust should be a geographic or population.
