摘    要:该项研究通过系统调查,把稻田节肢动物群落按营养和取食关系划分为三个营养层(基位物种,中位物种,顶位物种)和不同的功能集团,在物种、功能集团和营养层三个组织层次水平上探讨了稻田节肢动物群落的结构和多样性,较全面地考察了整个群落中物种和功能集团在时间上的结构动态、功能关系和数量消长规律。结果表明:功能集团多样性与种多样性的变化趋势较一致,在群落研究中似乎可以用对功能集团的研究代替对种的研究,从而简化物种间复杂的网络关系,认为这是研究群落物种间功能关系的途径之一。营养层多样性在时间序列过程中波动性较小,所以可用于群落相似性和稳定性的分析。研究分析了中性昆虫对害虫调控的意义,认为对于天敌作用的评价应以整个群落为基础,全面考虑天敌、害虫、以及中性昆虫的数量、丰盛度、空间时间生态位等信息。

关 键 词:褐飞虱  节肢动物群落  功能集团  丰盛度  多样性

Abstract:In this study, the arthropod community in paddy field was divided into three nutrient classes (top-species, intermediate-species and basal-species) and various guilds. The component structures and biodiversity of the arthropod community were investigated according to the species, guilds and nutrient classes. The results indicated that the guilds's biodiversity was similar to the species biodiversity. If the species was replaced by guilds in studying the structure and function of community, the complicated network relationship among species in the community would be simplified. The neutral insects in a paddy arthropod community play an important role in pest population dynamics. The function of natural enemy in the community should be evaluated on the numbers, the temporal and spatial niches of natural enemies, pests and neutral insects.
Keywords:Nilaparvata lugens (Stal)  community  guild  abundance  biodiversity
