摘　　要：通过对葡萄园不同时期害虫和天敌群落物种及其数量的调查,探讨了稀土元素对葡萄园节肢动物群落结构的影响,研究2种稀土离子钕元素和镧元素对葡萄树体节肢动物群落及地表节肢动物群落结构的影响。从整个葡萄生育期的各处理中节肢动物总群落及亚群落结构和发生规律研究来看,将稀土元素处理的葡萄园和2个对照进行比较,节肢动物群落及其各亚群落在物种数、物种性对丰富度、个体数、多样性来看,有着加速物种数聚集,延缓植食类亚群落衰退的作用。该研究为稀土元素用于葡萄园害虫综合治理中提供了科学依据。The aim was to discuss the effects of rare earth elements on the community structure of arthropod in the graperies. Arthropod community in the graperies had been investigated from April to October. Through analysis on arthropod community composition, structure and diversity, the effects of rare earth elements on arthropod community were discussed. The results showed that there were significant differences between the treatments and the control in arthropod species number and abundance, quantity of main species, and diversity index. The temporal and spatial structure of the four subcommunities and their numeral dynamics in early and late grape fields were analyzed in this paper. The study could provide scientific basis for protecting and using rare earth elements.
