摘    要:落叶松根系呼吸速率在6~9月期间逐渐升高,8月达到高峰,之后明显下降.幼林根系呼吸速率和根系呼吸占土壤总呼吸的比例均高于成熟林.根系呼吸速率与根生物量呈线性相关,与土温呈指数相关,与土壤含水量无明显相关关系,但温度较高时,土壤湿度的增加能促进根系呼吸.成熟林和幼林根系呼吸的Q10值分别为5.56和4.17.

关 键 词:兴安落叶松  根系呼吸  土壤总呼吸

Abstract:Root respiration rate of the larch plantations of both ages increased from June to Aug., and peakedin Aug. After Aug., the root respiration rate declined sharply. The root respiration rate and percentage of rootrespiration to total soil respiration of the young forest were higher than those of the mature forest. The rootrespiration was linearly correlated with root biomass and was exponentially correlated with soil temperature.There was no obvious correlation between the root respiration and soil moisture, but when soil temperature washigher, increase of soil moisture could promote root respiration. Q10 values of the root respiration of the matureforest and the young forest were 5.56 and 4.17 respectively.
Keywords:Q10
