摘要
2011、2012年生长季内利用静态箱-气相色谱法,研究了大兴安岭寒温带典型湿地白桦(Betula platyphylla)岛状林沼泽土壤呼吸速率的季节动态及其主要环境因子,利用壕沟隔断法对土壤呼吸各组分间的差异进行研究。结果表明:生长季白桦岛状林沼泽土壤呼吸速率具有明显的季节性规律。
In the growing seasons of 2011 and 2012,the static box-gas chromatography method was used to study the seasonal dynamics of the soil respiration rate of the Betula platyphylla island-type forest marsh in the Daxing’anling cold temperate zone and its main environmental factors.The differences between the components of soil respiration were studied.The results showed that the respiration rate of birch island-like forest swamps in the growing season had obvious seasonal patterns.
