摘要/Abstract

摘要： 对桃园节肢动物群落进行了系统调查,并对数据进行了数学分析.结果表明,群落与植食动物亚群落的多样性指数相关系数为0.9480,两者极显著相关;群落与捕食动物亚群落的多样性指数相关系数为0.7855,两者极显著相关;两个亚群落的多样性均与群落多样性有关,两个亚群落多样性指数间相关系数为0.6741,两者显著相关;群落多样性指数与群落均匀度指数间相关系数为0.7870,两者极显著相关;群落多样性指数与两个亚群落均匀度指数之间均不相关.群落多样性指数(H'),与捕食性动物个体数(S_d)和植食性动物个体数(S_z)之比值(S_d/S_z)相关系数为0.8112,两者极显著相关;与群落物种数(S_s)和个体数(S_i)之比值(S_s/S_i)相关系数为0.9188,两者极显著相关;与捕食动物类群(科)数(S_pl)和植食动物类群(科)数(S_zl)之比值(S_pl/S_zl)不相关.

Abstract: This study showed that the diversity index of total arthropod community in peach orchards was significantly correlated to the diversity index of both phytophages (r=0.9480) and predators sub-communities (r=0.7855),and the two sub-communities were correlative (r=0.6741).It was also significantly correlated to the evenness index of total community (r=0.7870),but not correlated to the evenness index of both sub-communities.The diversity index (H') of total community was significantly correlated to the ratio of predators individuals (S_d) and phytophages individuals (S_z) (r=0.8112) and of species (S_s) and individuals (S_i) (r=0.9188),but not correlated to the ratio of predators (S_pl) and phytophages (S_zl).
