| 摘 要： | 利用气象梯度观测塔安装的土壤热通量板和净辐射传感器等设备对大兴安岭的兴安落叶松林土壤热通量的特征及与净辐射相关性进行了分析。结果表明：5cm土壤热通量的日变化和年变化均呈现出＂S＂形,土壤热通量在年度6月达到最大值747.35W·m-2,12月达到最小值-394.55 W·m-2,全年总土壤热通量为738.89 W·m-2,全年土壤总的热通量为正值,土壤为热汇。对5cm土壤热通量和冠层净辐射相关性进行了回归分析,无论在日尺度还是在年尺度上均达到显著相关性。

| Abstract: | Characteristics of soil heat flux and correlation of net radiation for Larix gmelinii were analyzed by using equipments （soil heat flux plates ~ net radiation sensors which were installed by the gradient meteorological obser- vation tower. Result shows that： the diurnal ＆ annual variation of soil heat flux with 5 cm all appear ＂S＂ shape ;soil heat flux reach the maximum （747.35 W·m-2） in June of the very year;soil heat flux reach the minimum （-- 394.55 W· m-2） in December; the annual total soil heat flux is 738.89 W · m-2 ;the annual total soil heat flux is positive;soil is as heat sink. Soil heat flux ＆ net radiation of canopy at the depth of 5 cm were conducted correlation regression analysis,and they all reach significant correlations either in the day or in the year scale. |
