| 摘 要： | 基于有林地和无林地的土壤温度数据,对不同土层深度温度的日变化规律进行研究。结果表明:土壤温度随土层深度的增加而降低,且土层越深波动越小,最终稳定在15~20 cm处;有林地能够消减土壤最高温度,延缓土壤的过快升温;林木的郁闭度对土壤温度变化规律也有一定影响。

| Abstract: | The regulation of temperature diurnal variation based on temperature data of different depth of forested land and non-forest land was studied.The result showed that the temperature would go down along with the depth of soil,and then the fluctuation of temperature became less,until steady at 15～20 cm.Forested land was helpful for alleviating canicule.The different canopy density also affected the soil temperature. |
