地上植食性昆虫对土壤生态系统影响的研究进展

摘要

Aboveground and belowground biota interact intimately and influence the terrestrial ecosystem process together. Numbers of studies have revealed that the aboveground herbivorous insects can not only influence the aboveground parts of vegetation and other animal communities, but also exert indirect strong effects on belowground biota community and ecosystem process, which may further feedback to aboveground ecosystems. To gain a better understanding of the effects of aboveground herbivorous insects on soil ecosystem and the associated mechanisms, this review summarized the effects of aboveground herbivorous insects on soil biota at different trophic levels of soil food web and the relevant soil nutrient dynamics, discussed the pathways through which the insects affect soil ecosystem and the regulatory factors, and also proposed the future research directions.%地上地下生态系统之间存在着密切的联系,二者相互作用,共同影响陆地生态系统过程.越来越多的研究表明,地上地下之间的相互联系还受到植食性动物取食作用的调节.地上植食性昆虫不仅可以改变地上植物或动物群落,还可以间接地影响土壤生态系统中的生物群落和相关的土壤过程,进而对地上生态系统形成反馈.本文综述了地上植食性昆虫对土壤食物网中不同营养级的生物群落,以及相关土壤过程的影响;在已有研究报道的基础上,分析并归纳了地上植食性昆虫影响土壤生态系统的途径和调控因素等,旨在较为全面地总结地上植食性昆虫对土壤生态系统的间接影响以及相关的影响机制,并对今后的研究方向作了初步展望.
