中文摘要：

于2011年10月至2012年4月对长白山2种落叶松林内笃斯越桔群落的大气温度、空气相对湿度和土壤温度进行了测定。结果表明：长白山笃斯越桔群落越冬期长达约7个月，最寒冷的1月份平均温度约为-30℃，极端低温达到-40℃以下；越冬期相对湿度较低、空气干燥，尤其是仲冬至早春季节湿度偏低；越冬期土壤上层温度较低且变幅较大，下层较高且变幅较小，20cm土层的极端低温约为-15℃。

英文摘要：

In October of 2011 to April of 2012, air temperature, air relative humidity and soil tempera- ture of Vaccinium uliginosum community were measured in two kinds of Larix olgensis forest of Changbai mountain. The results indicated tJlat：The wintering time was about seven months long, the average tem- perature and extremely low temperature were about - 30 ℃ and - 40 ℃, respectively; the relative hu- midity was low, and air was dry in wintering period, especially lower in midwinter to early spring; the variety of soil temperature was lower, and amplitude was greater on upper layer, higher and less on lower layer, extremely low temperature was about- 15 ℃ in 20 cm soil layer.
