森林凋落物分解是生态系统养分循环中的重要过程,通过分解向土壤释放植物所需养分,且产生大量CO2,对森林土壤肥力的维持及提高森林生产力有着重要的作用,并影响着陆地碳循环。文中评述了栽培密度、农林复合、混交林等营林措施及环境污染、温室气体、化感作用等环境问题与凋落物分解的相互关系,为深入研究凋落物分解规律及其在森林生态系统养分循环中的作用提供参考。
Forest litter decomposition is an important process in the ecosystem nutrient cycle. By decomposing the nutrients required by plants and releasing large amounts of CO2, forest litter decomposition plays an important role in maintaining soil fertility and improving forest productivity, and affects the terrestrial carbon cycle . The paper reviews the relationship between planting density, agroforestry, mixed forest and other forest management measures as well as the environmental problems such as environmental pollution, greenhouse gases and allelopathy, and the litter decomposition. In order to study the law of litter decomposition and its nutrient content in forest ecosystem, The role of circulation for reference.
