中文摘要：

了解土壤呼吸机理并准确预估土壤呼吸大小是评价全球碳收支的重要基础.以往构建的土壤呼吸预测模型常常忽略光合作用为根源呼吸提供底物这一生理生态过程,因此在预估土壤呼吸机理方面存在缺陷.鉴于此,本文概述了光合作用调控土壤呼吸的机理及其研究进展,介绍了主要的研究方法,并提出当前光合作用对土壤呼吸影响研究中存在的问题及未来该领域的研究重点.

英文摘要：

To understand the mechanisms of soil respiration and accurately estimate its magnitude are the crucial basis of evaluating global carbon balance. However, the previously built soil respiration forecast models usually neglect the physiological processes that photosynthesis supplies substrates for rhizospheric respiration, leading to the defect in evaluating the mechanisms of soil respiration. This paper summarized the research progress on the mechanisms of photosynthetic regulation and control of soil respiration, introduced the related main research methods, and discussed the existing problems and research hotspots.
