| 摘 要： | 利用开路涡动相关系统的连续观测结果,分析了长白山阔叶红松林2008年能量平衡各分量和蒸散量的特征,并对生长季和非生长季能量各分量和蒸散量的差异进行了比较.结果表明:该观测系统能量闭合度为72%,处于国际同类观测的中等水平;能量各分量日、季差异显著,生长季森林生态系统最主要的能量支出项为潜热通量,约占可用能量的66%,非生长季最主要的能量支出项为感热通量,约占可用能量的63%.长白山阔叶红松林2008年蒸散量为484.7 mm,占同期降水量(558.9 mm)的87%,证实森林蒸散耗水是我国北方温带森林最主要的水分支出项.

| Abstract: | Based on the continuous measurements of an open-path eddy covariance system,this paper analyzed the characteristics of energy balance components and evapotranspiration in a broad-leaved Korean pine forest in Changbai Mountains in 2008,as well as the differences of energy balance components and evapotranspiration between growth season and dormant season.For the test forest,the year-round energy balance closure was 72%,being at a medium level,compared to the other studies in the Fluxnet community.The energy b... |
