摘　　要：环境问题和节能减排是二十一世纪全社会关注的重点,陆地生态系统作为全球主要的碳库之一,是实现“双碳”目标的重要支撑与保障。本文主要总结了沙漠生态系统土壤有机碳(SOC)及无机碳(SIC)的研究进展,探讨土壤理化性质、植被、微生物、气候及人为活动对沙漠土壤碳储量的影响,可为了解全球气候变化背景下沙漠脆弱生态系统的碳固定路径提供参考,为未来开展沙漠生态系统碳循环理论研究提供新的视角。Environmental issues and energy conservation and emission reduction are the key concerns of the whole society in the 21st century.As one of the major global carbon pools,terrestrial ecosystems are an important support and guarantee for the realization of the goal of“double carbon”.This paper summarized the research progress of soil organic carbon(SOC)and inorganic carbon(SIC)in desert ecosystems.And then explored the effects of soil physical and chemical properties,vegetation,microorganisms,climate and human activities on soil carbon storage in deserts,which can provide theoretical basis for understanding the carbon fixation pathway of desert fragile ecosystems under the background of global climate change and provide new perspectives for the future research of carbon cycle theories in desert ecosystems.
