摘要
土壤呼吸作为陆地生态系统碳循环的重要组成部分,其微小变化会直接影响碳循环过程。目前,土壤呼吸对全球大气CO_(2)浓度升高响应已引起广泛关注。本文初步总结了模拟土壤呼吸对CO_(2)浓度升高响应的研究进展,尤其关注CO_(2)浓度升高对土壤呼吸组分的影响差异和微生物调控机制等。深入认识CO_(2)浓度升高-微生物-土壤呼吸之间的关系,有利于在未来全球变化的背景下,提高土壤碳汇功能。在此基础上,指出了当前土壤呼吸对CO_(2)浓度升高的响应过程中存在的问题和不足,并对未来研究提出展望。
As an important part of carbon cycle in terrestrial ecosystem,small changes in soil respiration will directly affect the carbon cycle process.The effect of elevated CO_(2)on soil respiration has attracted extensive attention.The study preliminarily summarized the progress in simulating the impact of elevated CO_(2)concentration on soil respiration,especially focused on the microbial regulation mechanism of elevated CO_(2)concentration on soil respiration.Understanding the relationship between climate-microorganism-soil respiration,which is conducive to improving soil carbon sink function under the background of future global change.On this basis,some problems in the process of the effect of elevated CO_(2)concentration on soil respiration were pointed out,and the future researchprospects were put forward.
