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,20 cm土层的极端低温约为-15℃。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.
