栗园节肢动物群落结构与组织学研究

根据皖东栗园节肢动物群落物种的组成和数量,按照营养和取食关系,将群落划分为植食类、捕食类、寄生类和中性类亚群落,按照系统分类的方法,将每个亚群落分成不同的功能类群,采用群落分析的多个参数比较分析了群落的结构.结果表明,皖东栗园节肢动物调查到了178种101科,其中植食类、捕食类相对丰盛度分别为0.93295和0.04062,各亚群落的优势集中性表现为寄生类(0.68686)>植食类(0.29356)>捕食类(0.24680);H′多样性指数和Hill多样性指数(N1、N2)均为捕食类节肢动物亚群落>节肢动物总群落>植食类节肢动物亚群落.

Structure and Histology of Arthropod Community in Chestnut Orchard

The arthropod community was divided into four sub-communities,i.e. phytophages, predators, parasitoids and neutralities according to nutrition and hunting category.The structures of arthropod community and different sub-communities were analyzed by using a number of community parameters. The results indicated that there were 178 species of arthropod belonging to 101 families, including 117 species of phytophages representing 65 families;40 species of predators representing 21 families; 15 species of parasitorids representing 9 families; 6 species of neutralities representing 6 families in chestnut orchard.The relative abundance of phytophages and predators were 0.93295 and 0.04062 respectively. The dominant concentration of parasitorids was 0.68686, larger than that of phytophages (0.29356) and predators (0.24680). The other parameters such as diversity index (H,Hill N_1,Hill N_2),manifested the same trends,that is predators sub-community>arthropod community>phytophages sub-community.
