林火干扰对森林植被碳库影响的研究进展

Effect of Forest Fire on Forest Vegetation Carbon Storage

林火干扰是全球森林生态系统发展的主要动力之一。从研究方法现状、森林植被碳储量、景观尺度等3个方面综合论述了林火干扰对森林植被碳库的影响,以及景观尺度上林火干扰因子对森林碳储量的耦合作用。指出当前林火干扰对森林植被碳储量影响在景观尺度上研究较少、研究因子单一和在不同火烧烈度上对森林碳储量的影响研究不充分等问题,提出为准确量化林火干扰对森林碳储量的影响,需要揭示林火干扰特征对森林碳库的影响机制及碳分布格局的变化特征。

Forest fire is the main driver of forest ecosystems development in the worldwide. The paper summarized the effects of forest fire on forest vegetation carbon storage from three aspects of research status,forest vegetation carbon storage,and landscape scale,and the coupling of forest fire disturbance on forest vegetation carbon storage in landscape scale also been studied. The results showed that the research on current forest fire disturbance on forest vegetation stocks at the landscape scale was few. In order to accurately quantify forest fire disturbance on the forest carbon stocks,it is necessary to discover the impact mechanism of forest fire disturbance characteristics on forest carbon stock change,and carbon distribution pattern.
