摘　　要：本文分析了杜香落叶松原始林内近地面气温、近地面净辐射、土壤热通量和地温等因子在生长季的变化 。The Changes of near ground temperature?near ground pure radiation?soil heat feux and ground temperature of Ledum-Larix genlini virgin forest in growing season were analyzed in the paper.The results show that the soil heat and the depth of the melted soil affected the growth of plant roots,especially the tree roots.

关 键 词：杜香落叶松 土壤热量 寒温带 冻土 原始林
