植物多样性对土壤动物影响的研究进展

生物多样性与生态系统功能一直是生态学研究的一个热点。近些年来的研究表明,植物多样性除了影响陆地生态系统地上部分的初级生产力等生态系统功能,还会间接影响地下生物多样性及土壤生态系统过程。本文概述了植物多样性对土壤动物的影响及其主要机制,归纳了植物多样性通过改变输入土壤中的资源数量与资源多样性、微生境结构、土壤环境因子等影响土壤动物的途径。目前关于土壤动物群落对植物多样性的响应仍存在很多问题和争议,本文总结了需要进一步深入研究的方向,特别指出了要加强研究影响植物多样性与土壤动物关系的生物与非生物因子、后续的生态效应和反馈、不同机制和途径的贡献定量化等。

Study Advances in Plant Diversity Effects on Soil Fauna

The relationship between biodiversity and ecosystem functioning has been a hot topic in the research field of ecology. Research in recent years has shown that plant diversity not only influences above-ground ecosystem function, such as primary productivity, it also influence below-ground biodiversity and soil ecosystem processes indirectly. This review summarizes the effects of plant diversity on soil fauna and the main mechanisms. Plant diversity may affect soil fauna through several pathways, such as changing the quantity and diversity of resource input to soil, the microhabitat structure and soil environment factors. There are still a lot of controversies about how the soil fauna respond to plant diversity. This review emphasizes several further researches, including the impact factors influencing plant diversity and soil fauna relationships, the subsequent ecological effects and feedbacks, quantification of the contribution of different mechanisms and pathways.
