摘要: 中小型土壤动物是地下生态系统重要的参与者,在地下生态系统物质循环和能量流动过程中均扮演着重要角色。本研究通过对40篇文献进行Meta分析,探讨放牧对中小型土壤动物群落结构变化的影响,结果表明:(1)放牧会提高中小型土壤动物丰度,但会降低物种数和多样性指数。(2)放牧通过影响植物群落和土壤理化性质,进而间接影响中小型土壤动物的群落结构。(3)相关性分析表明,在围封处理下,中小型土壤动物丰度与土壤含水量、速效钾呈正相关;在放牧处理下,中小型土壤动物丰度与土壤含水量、速效钾、全磷呈显著正相关(P<0.01)。(4)结构方程模型结果显示,在围封处理下,土壤全氮对中小型土壤动物丰度产生显著正效应(标准化回归系数β=0.19,P<0.05)。综上所述,中小型土壤动物作为地下生态系统的重要参与者,其对放牧的响应方式,有利于为各地区制定更合理且科学的放牧方式。

Abstract: As the key component of the belowground ecosystem,meso-micro soil fauna play an important role in the material cycle and energy flow of underground ecosystem. We aimed to assess the influence of grazing on the community structure of Meso-micro soil fauna using Meta-analysis. The results showed that:(1) Grazing increased the abundance of Meso-micro soil fauna,but decreased the number of species and the diversity index. (2) Grazing indirectly affected the community structure of Meso-micro soil fauna,through its influence on plant communities and soil physicochemical properties. (3) Correlation analysis showed that the abundance of Meso-micro soil fauna was positively correlated with soil moisture and available potassium (P<0.05) in enclosure treatment group,whereas the abundance of Meso-micro soil fauna was significantly positively correlated with soil moisture,available potassium,and total phosphorus (P<0.01) in grazing treatment group. (4) Structural equation models showed that soil total nitrogen had positive effect on the abundance of Meso-micro soil fauna in enclosure treatment. In summary,as an important participant of the underground ecosystem,Meso-micro soil fauna response to grazing was conducive to formulating more reasonable and scientific grazing methods for various regions.
