摘要
土壤动物在农业生态系统腐屑食物网中占有重要地位 ,它们参与土壤有机质分解、植物营养矿化及养分循环作用。国外许多试验表明 ,土壤运动及其多样性对全球变化 ,尤其是大气CO2浓度升高产生正向、中性和负向的响应。本文首先介绍了土壤动物的分类及在养分循环中的作用 ,其次论述了土壤动物对大气CO2 浓度升高响应的研究进展 。
Soil fauna play significant roles in the detritus food webs of agroecosystems, they are the essential contributors to the decomposition of soil organic matter, mineralization of plant nutrients and nutrient cycling. Some evidence indicates that soil fauna and biodiversity of the detritus food webs appear to show positive, neutral or negative responses to global change, especially atmospheric CO 2 enrichment across different studies. In this paper, firstly, the classification of soil fauna and their roles in nitrient cycling were introduced; secondly, the advance of study on the response of soil fauna to elevated atnospheric CO 2 was discussed; finally, a few of priorities of the field in China in the near future were presented.
