植物对昆虫多样性的影响

Effects of plant on insect diversity:A review

昆虫多样性是生物多样性的重要组成部分,植物及植物群落对昆虫多样性有极为重要的影响。本文从植物不同方面对昆虫多样性影响进行阐述:1)植物高度与盖度的增大为昆虫提供更多的生存空间,增加了昆虫多样性;2)基因多样性高的植物种群能提供更大生态位,使昆虫多样性增加,个体数量增大;3)植物物种和功能群多样性增加,使得有更多的物种数量可以支持更多昆虫;4)植物生产力增加使昆虫需要的食物资源增加,昆虫多样性随之增大。已有相应假说和理论,解释植物对昆虫多样性影响机制。同时,指出了植物对昆虫多样影响存在问题以及今后发展方向。

Insect diversity is an important component of biodiversity, while plant and plant community have crucial effects on it. This paper reviewed the effects of plant and plant community on insect diversity from the aspects of 1 ） the increase of plant height and cover provides insects more living space, and consequently, increases insect diversity, 2） the plant populations With high genetic diversity offer a greater variety of niches, leading to a greater diversity and altered abundance of insect, 3 ） the increase of plant species and functional group diversity supports the consumers to have more quantities of primary producers, and 4） the increase of plant productivity increases the insect diversity by supplying more food resources. Relevant hypotheses and theories that explained the mechanisms of the effects of plant and plant community on insect diversity were introduced, and the existing research problems and future developments about the effects of plant and plant community on insect diversity were pointed out.
