| 摘 要： | 研究大九湖泥炭湿地通量,为准确评估泥炭地生态系统与大气间的物质和能量交换提供基础数据。利用涡度相关系统对神农架大九湖2015年9月～2016年8月的净辐射、显热通量、潜热通量及土壤热通量进行了为期1年的连续观测。结果表明:1)泥炭地全年净辐射为3 146.91MJ/m2,显热通量为931.79MJ/m2,潜热通量为1 762.40MJ/m2,土壤热通量为22.26MJ/m2;能量分配主要以潜热为主,占净辐射的56%。潜热通量为能量散失的主要形式,土壤表现为热汇。2)各能量分量季节变化明显,10月、1月、4月及7月的日变化均以净辐射为基础,呈相似的单峰型曲线变化。3)波文比逐月变化不规律,月平均波文比为0.65、波动在0.34～1.06,年波文比为0.53,全年能量分配潜热通量大于显热通量。4)神农架大九湖泥炭地年能量闭合度为0.86,存在14%的能量不闭合。不闭合的原因可能与下垫面状况、季节变化及平流的影响产生的波动等相关。
