摘    要:在全球性气候变化背景下,极端降雨事件频发,总结土壤动物多样性与降雨变化间的关系及其响应机制,有助于理解全球变化对土壤生态系统结构与功能的作用过程,对于探讨陆地生态系统应对全球变化具有重要科学意义。荒漠草原生态系统极度脆弱,对气候变化敏感,但是关于荒漠草原土壤动物与降雨变化间关系的研究报道比较少,严重制约了对荒漠草原生态系统的有效管理和可持续利用。本文从地上、地面和地下3个方面总结了土壤动物和降雨变化间的关系,并就荒漠草原土壤动物应对气候变化研究提出了一些建议。研究表明,降雨变化直接影响土壤动物群落结构;土壤动物对降雨变化反应强烈,不同动物类群产生了积极的响应规律;某些土壤动物类群对于降雨变化还具有重要指示作用。在荒漠草原生态系统中,今后需要从降雨变化对土壤动物产生的长期影响、土壤动物对降雨变化的适应方式和某些动物类群对土壤水分敏感性以及土壤动物与气候变化间的互为反馈关系等方面加强研究。

关 键 词:降雨变化  土壤动物  全球变化  荒漠草原

Abstract:Under the background of global climate change, the events of extreme rainfall occur frequently. To summarize the relationships between soil faunal diversity and rainfall change and the response mechanisms of soil fauna helps understand the affecting process of global change on the structure and function of soil ecosystem, and has scientific significance in clarifying the responses of terrestrial ecosystem to global change. Desert steppe ecosystem is very fragile and sensitive to climate change, but the studies on the effects of rainfall change on the soil faunal diversity are fewer, which constrain the rational management and sustainable utilization of the ecosystem. This paper summarized the relationships between soil fauna and rainfall change from the aspects of aboveground, ground, and underground, and gave some suggestions for the future studies on the responses of soil fauna to rainfall change in desert steppe. Previous studies have showed that there is a direct effect of rainfall change on the soil faunal community structure. Soil fauna has strong response to rainfall change, and some soil faunal groups can be regarded as an important indicator for the rainfall change. It is suggested that for the desert steppe ecosystem, future studies should be focused on the long-term effect of rainfall change on soil fauna, the adaptation ways of soil fauna to rainfall change, the sensitivity of some soil faunal groups to soil water content, and the feedback relationships between soil fauna and climate change.
Keywords:rainfall change  soil fauna  global change  desert steppe
