- 摘要:
- 荒漠生态系统作为全球陆地碳库的重要组成部分，其土壤碳密度动态对调节大气CO2浓度及应对气候变化具有关键作用。该文系统综述了近年来荒漠土壤碳密度的研究进展，重点探讨了有机碳（SOC）与无机碳（SIC）的分布特征、驱动机制及人为干预的影响。旨在填补荒漠碳密度研究的系统性空白，强调SIC在碳汇功能中的核心地位及人为管理的双刃剑效应。未来需重点突破以下方向：1）开发高分辨率遥感与原位监测技术，构建多尺度碳密度数据库；2）深化SIC气候反馈机制研究，优化碳模型对干旱区的适应性；3）制定基于碳密度保护的荒漠土地可持续利用策略，推动“自然-人为”协同调控。通过跨学科协作与全球数据共享，荒漠生态系统有望成为实现碳中和目标的重要自然解决方案。
- Abstract:
- Desert ecosystem is an important part of the global terrestrial carbon pool，and its soil carbon density plays a key role in regulating atmospheric CO2 concentration and coping with climate change.In this study，we systematically reviewed the research progress of desert soil carbon density in recent years，focusing on the distribution characteristics，driving mechanism of organic carbon (SOC) and inorganic carbon (SIC)，and the influence of human intervention.This review aims to fill the systematic gap in the study of desert carbon density，emphasizing the central role of SIC in carbon sink function and the double-edged sword effect of man-made management.Future breakthroughs should be made in the following directions:1) Develop high-resolution remote sensing and in-situ monitoring technology to build multi-scale carbon density database；2) Deepen the study of SIC climate feedback mechanism and optimize the adaptability of carbon model to arid areas；3) Develop strategies for sustainable use of desert land based on carbon density protection，and promote ‘nature-human’ collaborative regulation.Through interdisciplinary collaboration and global data sharing，desert ecosystems are expected to be an important natural solution to achieving carbon neutrality.
