The biggest proportion in the heat balance is the potential heat flux, followed by sensible heat flux and soil heat flux.
在绿洲荒漠过渡区生态系统的热量平衡中，占比例最大的是潜热通量，其次为感热通量和土壤热通量。
In loess plateau, at the daytime, the net radiation contributes mainly to the latent heat flux, the sensible heat flux is minor and the soil heat flux is least.
在黄土高原半干旱地区：白天，潜热通量在净辐射通量的分配中所占的份额最大，其次为感热通量，土壤热通量最小。
The experiments identify that with the increasing of LAI , the ratio of soil heat flux to net radiation decreases from 0 13 in the jointing to 0 06 in the milking.
随着叶面积指数（LAI）的增加，土壤热通量与净辐射之比，由返青初期的0．13迅速下降，直至较为稳定的0．06。
