摘  要：
本文通过对大兴安岭原始林区的实测数据进行分析研究。结果表明:1)空气温度的变幅大于树干温度,树干温度与空气温度的日变化呈单峰型曲线;2)树干温度与空气温度的季节动态为生长季的树干温度变幅明显高于非生长季,即从春季到夏季树干温度随空气温度呈持续升高态势高峰值出现在7月或8月而后逐渐下降;3)树干温度与空气温度呈线性关系,树干呼吸与气温变化相一致。树干呼吸有明显的变化规律:日变化表现为双峰型,有"午休"现象,季节变化表现为生长季的树干呼吸明显高于非生长季。

摘  要：
on the basis of an analysis on the actual experimental data obtained from the area of virgin forests of The Greater Hinggan Mountain,the results show that 1) the variation scope of air temperature is greater than the stem temperature,while the daily changes of both the air temperature and the tree stem temperature took on a single peak curve.2) The study on the seasonal changes of both stem temperature and air temperature shows that the variation scope of tree stem temperature during the growing season was significantly higher than that of the non-growing season,showing a constantly increasing trend of the tree stem temperature from spring to summer along with the air temperature,with the peak occurring at July or August and then gradually decreased.3) The stem temperature and air temperature shows a linear relationship.The stem respiratory varies along with air temperature.The stem respiratory obviously shows a regular variation that the daily changes took on two peaks curve called "noon rest" phenomenon.The seasonal variation shows the respiratory of tree stem during the growing season is stronger than non-growing season.
