寒温带杜香落叶松原始林土壤热量状况的研究
STUDIES ON THE SOIL HEAT CONDITION OF LEDUM-LARIX GEMLINI VIRGIN FOREST IN COLD TEMPERATE ZONE OF INNER MONGOLIA
【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 ,说明土壤热量状况的变化规律以及冻土的最大可融化深度对森林植物根系特别是对林木根系生长的影响
【Abstract】 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.
