土壤微生物与其物理环境的相互作用影响其呼吸、生长和分裂的能力。这些环境因素之一是土壤的湿度。我们在25年前发表的研究表明，微生物呼吸与土壤含水量呈线性关系，与水势呈对数线性关系。这篇论文是由来自土壤科学、物理学和微生物学不同领域的两名年轻研究人员合作完成的。这个项目不仅是由我们的好奇心驱动的，也是在没有当前科学管理体系常见的限制的情况下自由运作的。引文历史显示了三个高峰，1989年，1999年和2002年至今。有趣的是，年度引用率一如既往地高。最初的峰值是由于工作的应用研究石油微生物过程。第二个高峰与模拟建模的兴起有关，第三个高峰与气候变化研究结果的相关性有关。在这篇文章中，我们的论文是重新评估，在随后的研究，允许分离变量的原则进行测试。这一重新评价进一步证实了土壤呼吸与含水量之间的线性关系，并提出了土壤呼吸与含水量的比例关系。最后，进一步的研究建议和最近的工作油的气体输送的物理简要讨论。皇冠版权所有（C）2007由爱思唯尔有限公司出版。保留所有权利。
The interaction of soil microbes with their physical environment affects their abilities to respire, grow and divide. One of these en vi roil men tal factors is the amount of moisture ill the soil. The work we published almost 25 years ago showed that microbial respiration was linearly related to soil-water content and log-linearly related to water potential. The paper arose out of collaboration between two young researchers from different areas of soil science, physics and microbiology. The project was driven by not only our curiosity but also the freedom to operate without the constraints common to the current system of science management. The citation history shows three peaks, 1989, 1999 and from 2002 to the present day. Interestingly, the annual citation rate is as high as it has ever been. The initial peak is due to the application of the work to studies oil microbial processes. The second peak is associated with the rise Of Simulation modelling and the third with the relevance of the findings to climate change research. In this article, our paper is re-evaluated in the light of subsequent Studies that allow the principle of separation of variables to be tested. This re-evaluation lends further credence to the linear relationship proposed between soil respiration and water content, A scaled relationship for respiration and water content is presented. Lastly, further research is suggested and more recent work oil the physics of gas transport discussed briefly. Crown Copyright (C) 2007 Published by Elsevier Ltd. All rights reserved.
