摘要
林火作为陆地生态系统最活跃的生态因子,是生物地球化学循环的关键驱动因素。研究森林燃烧剩余物属性及其生态学功能,有助于深入理解地球生物圈对林火干扰的响应过程,对科学制定植被经营、林火管理措施也具有重要的理论意义。文中综述森林燃烧剩余物的国内外研究进程,阐述燃烧剩余物的主要成分,介绍林火对燃烧剩余物关键地球化学特征的已知影响,并从环境因素和生物因素方面总结燃烧剩余物在火烧迹地生态恢复过程中的重要性,指出目前研究存在的主要问题及未来的研究方向。
As the most active ecological factor of terrestrial ecosystem,wildfire is the key driving factor of biogeochemical cycle.The study of the properties and the ecological function of forest-fire residues is conducive to understanding the response process of the earth biosphere to fire disturbance,and also of important theoretical significance for science-based development of vegetation management and wildfire management measures.This paper reviews the research progress of forest-fire residues at home and abroad,expounds the main components of forest-fire residues,introduces the known influence of wildfire on the key geochemical characteristics of forest-fire residues,and summarizes the importance of forest-fire residues in the ecological restoration process of burned area from the perspective of environmental and biological factors,and points out the existing problems and future research directions.
