| 摘 要： | 通过对樟子松林地的气温、湿度、风速、地温等气象因子的测定，采用微气象法求得樟子松林地热收支日变化进程及热量平衡方程。结果表明：净辐射日总量为１３９．５７Ｗ／ｍ２，主要用于蒸散耗热，即潜热输送（８７．８７Ｗ／ｍ２）远大于感热输送（３６．１６Ｗ／ｍ２）和土壤热输送（１１．５４Ｗ／ｍ２），潜热通量与土壤热通量日变化规律明显，感热通量日变化规律不明显。

| Abstract: | By the determination of air temperature,humidity,wind speed and ground temperature etc.climatic factor,Using the microclimatology,this paper works out the daily changes of heat budget and draw the heat balance equation of Pinus sylvestris var.mongolica forest.The result show as:The total net radiation is 139.57W/m 2.It mainly consume its heat to transpiration and evaporation.It is to say,latent fluxes(87.87W/m 2)is more bigger than sensible fluxes(36.16W/m 2)and soil heat fluxes(11.54W/m 2),The daily changes law of sensible fluxes and soil heat fluxes are evident;and the daily changes law of sensible is not obviors. |
