绿叶和正常凋落叶分解速率比较

森林每年产生大量的凋落物,这些凋落物的分解对于维持陆地生态系统碳循环具有重要意义。然而,以往的研究大多只关注了自然衰老、脱落的凋落物。目前,在全球变化的大背景下,极端气候事件愈发频繁,这必将导致越来越多的绿叶凋落。本研究对比研究了绿叶和正常凋落叶的分解速率,为全球变化预测模型的建立提供基础数据。

Forests produce a large number of litters every year,and the decomposition of these litters is of great significance for maintaining the carbon cycle of terrestrial ecosystems.However,previous research has mostly focused on natural aging and shedding of litter.At present,in the context of global change,the increasing frequency of extreme weather events is bound to cause more and more green leaves to fall.In this study,the decomposition rates of green leaves and normal litters were compared to provide basic data for the establishment of global change prediction models.
