摘　　要：炭屑是恢复古火灾的一个重要手段,同时也为认识古气候、古植被和古地理提供了重要途径.从炭屑研究方法和应用两个方面总结了国内近年来炭屑研究的进展,提出了炭屑研究中尚需解决的问题,展望未来研究的前景.炭屑的分析方法和现代过程研究可能是今后研究中急需解决的问题,这两个问题的解决可以使炭屑在古环境和人类活动研究中充分发挥其作用.而未来古环境中的炭屑研究需要填补一些地域上的空白.同时,高分辨率的炭屑记录应该是未来研究的趋势所在.In this paper, the latest advances of charcoal study in China are reviewed, including the study methods and applications. Charcoal research is still at the exploratory stage in China, so the problems and future research directions of charcoal are proposed. The reliable methods and understand of modern process are very important to reconstruct the past fire regimes （including natural and anthropogenic fire-regime types）, which are urgent need for the further study. It is necessary to extend the charcoal study to Northwestern China, where charcoal study is scarce but the significance of environmental change is pronounced. Finally, it is put forward that getting high resolution charcoal records should be the future study trend.
