生境破碎化对植物-昆虫及昆虫之间相互关系的影响

生境破碎化对生物多样性和生态系统功能影响是当前国内外生态学家研究的热点问题之一。文章针对生境破碎化的内涵、量度指标进行介绍,着重分析生境破碎化对植物-昆虫关系的影响,包括植物与植食性昆虫的关系、植物与传粉昆虫的关系、种子与种子捕食者的关系,植物及其分解者的关系,还分析生境破碎化对昆虫-昆虫关系的影响,包括昆虫及其拟寄生物的关系、捕食者与猎物的关系。通过对上述方面的阐述,旨在更好地理解生境破碎化对动植物群落相互关系产生的深刻影响,并提出今后研究中应注意的问题和研究热点。

Effects of habitat fragmentation on plant and insect-insect interactions

As one of major factors affected the loss of biodiversity and the function of ecosystems, habitat fragmentation has become one of central issues in conservation biology and ecology. In order to better understand the profound effects of habitat fragmentation on the interaction of plant and insect community, we introduce the meaning and quantitative measures of habitat fragmentation and the effects of habitat fragmentation on plant-insect interactions, including the plant-herbivore, plant-pollinator, seed-predator and plant-decomposer interactions. The effects of habitat fragmentation on insect-parasitoid and prey-predator interaction were also discussed. The issues should be paid attention to and hot spots of future study in this field were also given.
