摘要
大多数的研究表明：增加系统内生境和植被多样性，能增加天敌的物种丰富度和种群数量，降低或抑制有害节肢动物的种群密度。也有研究认为：生境与植被多样性对天敌数量的影响，天敌本身的运动迁移能力有非常重要的作用。本文还对生境与植被多样性影响节肢动物群落的生态学机制进行了讨论。
Most studies showed that the abundance of the natural enemies increased but that of the arthropod herbivores decreased or be controlled with the enhancing of the habitats and vegetational diversity. However, Some researches on the response of natural enemies to the habitats and vegetational diversity suggested that the movement ability of the natural enemies plays an important role in determining their abundance in diversified agroecosystem. The acting mechanisms of the vegetational diversity on arthropod community were reviewed in this thesis.
