对不同森林覆盖条件下的雪面热量收支进行了野外观测。利用基于实测资料建立的热量收支模型，研究了森林对雪面热量收支的影响。结果表明：（1）在森林附近的空旷场地，雪的表面积系数和雪的体积系数与森林中的表面积系数和雪的体积系数基本相同。2)辐射和感热收支随着被冠层遮挡的太阳辐射的百分比（Cf）的增加而减少。3)潜热收支与Cf无关。
Field observations on the snow surface heat budget are carried out under the different forest cover conditions. Using the heat budget model which was identified based on the observed data, the influence of forest on snow surface heat budget was examined. The results obtained are as follows; 1) Snow surface albedo and bulk coefficients at the open site adjacent to a forested area are almost same as the one in the forest. 2) Radiation and sensible heat budget decrease, as the percentage of solar radiation which is shielded by a canopy (Cf) increases. 3) Latent heat budget is independent of Cf.
