摘  要:
面积广阔的干旱荒漠区是一个非常重要的碳库,其碳循环也是影响大气CO_2浓度和全球变化的关键生态学过程。了解目前干旱荒漠区土壤碳循环研究现状对于准确评估全球碳收支具有重要意义。为给荒漠化防治和荒漠区水土资源的合理开发利用提供参考,本研究在对国内外干旱荒漠区土壤碳的分布、土壤碳通量过程、影响因素等方面的研究现状进行系统总结的基础上,指出当前仍存在诸如荒漠土壤固碳机理、碳转移和归宿、多尺度荒漠生态系统碳循环以及荒漠生态系统对气候变化的响应过程与机理等方面的不足,需要对这些科学问题做进一步的深入研究。同时,非常有必要建立全国性的荒漠生态系统碳通量观测网络,并加强荒漠土壤碳的可持续管理。

摘  要:
Large area of arid deserts is an important carbon pool,and the carbon cycle in these areas is also a key ecological process impacting atmospheric CO_2 concentration and global change.Understanding current research status of soil carbon cycle has important significance for accurately estimating global carbon budget.To provide references for desertification control and rational utility of regional soil and water resources,research status of soil carbon distribution,soil carbon flux process and influencing factors in arid desert regions were systematically reviewed.It was demonstrated that current studies are not sufficient on soil carbon sequestration mechanisms,carbon transfer and destination,multi-scale carbon cycle in desert ecosystem,response processes and mechanisms of desert ecosystem to climate change,and etc.Thus,these issues need further study.Meanwhile,it is very necessary to establish a national monitoring network of carbon fluxes for desert ecosystems,and to strengthen the sustainable management of soil carbon in deserts.
