摘    要:陆地生态系统由地上和地下两部分组成,二者相互作用共同影响生态系统过程和功能.土壤动物在生物地球化学循环方面起着重要作用.随着人们对土壤动物在生态系统过程中重要性的认识,越来越多的研究表明全球变化对土壤动物多样性产生深刻影响.土地利用方式的改变、温度增加和降雨格局的改变能直接影响土壤动物多样性.CO2浓度和氮沉降的增加主要通过影响植物群落结构、组成和化学成分对土壤动物多样性产生间接影响.不同环境因子之间又能相互作用共同影响土壤动物多样性.了解全球变化背景下不同驱动因子及其交互作用对土壤动物多样性的影响,有助于更好地预测未来土壤动物多样性及相关生态学过程的变化.

关 键 词:全球变化  土壤动物  多样性  生态过程

Abstract:Terrestrial ecosystem consists of aboveground and belowground components, whose interaction affects the ecosystem processes and functions. Soil fauna plays an important role in biogeochemical cycles. With the recognizing of the significance of soil fauna in ecosystem processes, increasing evidences demonstrated that global change has profound effects on soil fauna diversity. The alternation of land use type, the increasing temperature, and the changes in precipitation pattern can directly affect soil fauna diversity, while the increase of atmospheric CO2 concentration and nitrogen deposition can indirectly affect the soil fauna diversity by altering plant community composition, diversity, and nutrient contents. The interactions of different environmental factors can co affect the soil fauna diversity. To understand the effects of different driving factors on soil fauna diversity under the background of climate change would facilitate us better predicting how the soil fauna diversity and related ecological processes changed in the future.
Keywords:global change  soil fauna  biodiversity  ecological process
