摘　　要：以合肥市杏花林果科技示范园为例 ,研究了桃园节肢动物群落物种的组成和数量 ,对植食类、捕食类、寄生类和其它类 4种功能类群的相对丰盛度作了详尽的阐述。捕食类同植食类的相对丰盛度变化趋势一致 ,说明捕食类节肢动物是桃树生长期植食类害虫的重要天敌。The arthropod community was divided into four kinds of function communities phytophages,predators,parasitorids and neutralities, by the standard of nutrition and hunting.The relative abundance of these function communities was calculated.The shifting trend of relative abundance of predators was similar to the phytophages. Therefore the predators were important natural enemy that influenced phytophages at each growth period.
