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。
Through systematic investigation, the study divided the communities of arthropods in paddy fields into three nutrient layers (base species, middle species, top species) and different functional groups according to the relationship between nutrition and feeding. In species, functional groups and nutrition The structure and diversity of arthropod community in paddy field were discussed at the three organizational levels, and the structural dynamics, functional relationships and quantitative changes of species and functional groups in the whole community were comprehensively investigated. The results showed that the functional group diversity and species diversity trends are more consistent. It seems that community research can replace the study of species with functional group, thus simplifying the complex network relationships among species, which is considered as the research community species One of the ways of functional relations. Trophic layer diversity is less volatile in the time series, so it can be used for community similarity and stability analysis. The significance of neutral insects on pest control was analyzed and analyzed. The evaluation of the effect on natural enemies should be based on the whole community, taking full account of the information of natural enemies, pests and the number of neutral insects, abundance and space time niche.
