凋落物量对帽儿山4种森林土壤表面碳通量的影响
Effect of litter amount on soil carbon efflux of four forests in Maoershan Mountain
[目的]量化凋落物量变化对森林土壤表面碳通量的贡献,揭示其影响路径。[方法]本研究以帽儿山地区 4 种典型森林为研究对象,于 2020 和 2021 年的生长季设置 6 个不同的凋落物量的梯度,测定减少和增加不同枯落物量后的土壤表面碳通量、凋落物呼吸及主要环境因子。[结果]研究结果表明:随枯落物量的增加,土壤表面碳通量呈线性增长,4 种林型下 6 个凋落物处理凋落物处理对土壤表面碳通量的影响值的范围分别为:红松人工林 0.59～7.07μmol·…查看全部>>
[Objective]The aim of this study was to quantify the contribution of litter amount change to forest soil carbon efflux and reveal its influence path.[Method]In our study,four typical forests in Maoershan area were selected as the research objects.Six gradients of litter amount were set up during the growing seasons in 2020 and 2021,and the soil carbon efflux,litter respiration and important environmental factors were measured after different litter amount wa…查看全部>>
