ENERGY BALANCE ANALYSIS OF THE CONIFEROUS AND BROAD-LEAVED MIXED FOREST ECOSYSTEM IN DINGHUSHAN

  • 摘要: 能量平衡分析作为评价涡度相关法通量观测数据可靠性方法,备受学界重视。应用OLS(Ordinary least squares)和EBR(Energy Balance Ratio)2种方法,系统分析了广东省鼎湖山针阔叶混交林生态系统能量平衡特点,并分析各种涡度通量修正方法对能量平衡的影响,结果表明鼎湖山通量站平均能力平衡不闭合度为33%~47%,略高于普遍报道的不闭合度范围(10%~30%)。WPL修正、u*订正和坐标转换,使得能量平衡闭合度有所提高,但夜间特别是冬季能量平衡较差问题依然没有得到根本解决,表明夜间弱湍流并不是导致夜间能量平衡闭合度差的主要原因。为客观评价本通量站以及ChinaFLUX能量平衡状况和通量数据质量,确定涡度相关法CO2通量数据分析方法和改进策略提供依据。
