| 摘 要： | 中国北方农牧交错带,生态背景脆弱,在自然因素和人为活动的严重干扰下,生态系统遭到了严重破坏,草地面临严重沙化的威胁。而土壤动物是沙质草地生态系统物质循环和能量流动的不可或缺的一环,对保护和改善土地资源,控制由于各种原因而导致的土地退化、土地沙漠化有着重要意义。从沙质草地土壤动物的物种组成、研究方法、时空动态变化及其对生态系统的作用等方面进行了总结,分析了当前沙地土壤动物研究中存在的问题,并为未来沙地土壤动物研究提出了一些建议,从而为沙质草地生态系统恢复和重建及沙漠化逆转等提供了基础资料。

| Abstract: | The agro-pastoral transition zone of northern China has fragile ecological background, where the ecosystem has been severely destroyed strongly disturbed by natural factors and human activities, and the grasslands face the danger of desertification. Acting as an integral part in material circulation and energy flow of sandy grassland ecosystem, soil animals play an important role in protecting and improving land resources, controlling land degradation and other kinds of sandy desertification. The authors of this paper reviewed research of soil animals on aspects of soil animal composition, study method, space-time change, and function on sandy grassland ecosystem, etc. Furthermore, the current problems in soil animal research are analyzed, and some suggestions are also given. The study has provided scientific basis for restoration and reconstruction of sandy grassland ecosystem. |
