Impacts of forest degradation and damage on soil respiration in the Tiantong region, Zhejiang Province

  • 摘要: 以常绿阔叶林顶级群落为参照,选择了常绿阔叶林亚顶极群落、针叶林、灌丛和灌草丛代表不同退化类型;同时,以4种人工采伐处理代表常绿阔叶林不同受损程度,分别研究了不同退化和受损程度影响下,土壤的呼吸速率及影响因素.结果表明:(1)土壤呼吸速率具有明显的季节动态;(2)土壤呼吸速率分别在常绿阔叶林顶极群落与灌草丛最高,其次分别为针叶林和灌丛,常绿阔叶林亚顶极群落最低;(3)不同受损程度常绿阔叶林土壤呼吸速率无显著差异;(4)影响土壤呼吸速率的决定性因子为土壤C/N和pH,但在退化初期为土壤C/N,在退化后期为土温.可以认为,常绿阔叶林退化过程中控制土壤呼吸速率变化的主要因素逐步由生物因素向非生物因素转变.
