摘　　要： 研究了葛藤节肢动物中10个主要类群的相互关系.结果表明,10个类群呈总体正关联,由10个类群组成的45个种对中,有26个种对为正关联,其中14个种对存在有显著关联,其中蚂蚁类和豆突眼长蝽种对关联最强,其χ2值为23 96,相应的关联指数OI、DI、JI和YI分别为0 2925、0 9855、0 9714和0 1716;有19个种对呈负关联趋势,但均未达到显著水平. Relationships among ten main species groups of arthropods on Kudzu Pueraria lobata Ohwi, were analyzed. The results revealed that 45 couplets combined from 10 specie groups of arthropod were analyzed by correlation analysis. Fourteen couplets of them showed a positive correlation significantly, of which ants-Chauliops fallax species groups couplet showed the strongest positive correlation, and the χ~2-value was 23.96. Indexes of Ochiai, Dice, Jaccard and Yule were (0.292 5)、(0.985 5)、(0.971 4) and (0.171 6) respectively. Nineteen couplets of them showed a negative correlation.
