【摘要】 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。更多还原

【Abstract】 morphological characters of 12 speciesmen (male and female respectively) from 5 sites from the north and the south of Qinling mountains were measured and formed the data matrix. The matrix was standardized. The PCT distance index and square sum of deviation method were used to cluster. The rice grasshoppers in the south of Qinling mountains are similar, and should be a geographical race or popullation. The rice grasshoppers in the north of Qinling mountains are similar, and should be a geographical race or population. The rice grasshopper in the other side of loess plateau are a geographical race or population.更多还原
