Abstract: 为研究干旱区淡水湖泊人工、天然芦苇湿地土壤温室气体源汇强度及其影响因素，采用静态箱-气相色谱法，于2015年1月-12月对博斯腾湖人工和天然芦苇湿地土壤CO2、CH4和N2O通量进行全年观测。结果表明，人工芦苇湿地土壤CO2、CH4和N2O排放通量变化范围分别为：10.1-588.4mg m-2 h-1、2.9-82.4μg m-2 h-1和1.32-29.7μg m-2 h-1，天然芦苇湿地土壤CO2、CH4和N2O排放通量变化范围分别为10.3-469.6mg m-2 h-1、3.1-64.8μg m-2 h-1和1.9-14.3μg m-2 h-1。人工和天然芦苇湿地夏季土壤CO2排放通量均明显高于其他季节，而土壤CH4和N2O排放通量较大值多集中在春末夏初。全年观测期间，人工芦苇湿地土壤CO2、CH4和N2O排放通量高于天然芦苇湿地（P>0.05）；温度是影响人工、天然芦苇湿地土壤CO2和N2O排放通量的关键因素，近地面温度和5cm土壤温度与CO2和N2O排放通量呈现极显著的正相关关系（P 12484.21kg/hm2）。 read more here.
