| 摘 要： | 采用波文比能量平衡法对暖温带具有代表性的群落辽东栎纯林夏季热量平衡进行研究，测定热量平衡各分量。同时用TDM(Thermal Dissipation Method)法通过测定树干液流流量通量，得到蒸腾耗热通量，进而把蒸腾和蒸发从蒸发散中分开，把潜热通量分成蒸腾热适量和蒸发热通量。

| Abstract: | Forestry heat balance is a very important content in the forestry energy system. The heat balance in a forest could be obtained by means of Bowen-ration method. The daily trends of net radiation, the convective heat flux, the talent heat flux, the soil heat flux could also be obtained with this method. The sap flow flux could be gauged by using ICT-2000 auto meteorological station instrument with Thermal Dissipation Method, then the transpiration flux and transpiration heat flux could also be calculated, and the latent heat flux could be divided into transpiration heat flux and evaporation heat flux. Through gauging the heat balance of Quercus liaotungeusis Koidz deciduous broad-leaved stand under typical weather condition in summer in Taiyue Mount area of Shanxi Province, the total net radiation above canopy was 738.8 MJ/m 2, the canopy transpiration heat flux 139.8 MJ/m 2, the soil heat flux 45.1 MJ/m 2, the convective heat flux 261.7 MJ/m 2, and the evaporation heat flux 292.2 MJ/m 2 from July to August in 2001. |
