soil heat flux

A micro meteorological observation/ study in tree tea intercropping plantation and pure tea plantation for comparison have been carried out in Huangshan City, Anhui Province. The soil heat flux, latent heat flux and turbulence heat flux have been calculated by gradient and heat balance methods.

在安徽省黄山市，于夏季对杉&茶间作园与纯茶园进行了微气象观测研究，用梯度法和热量平衡法计算了土壤热通量、潜热通量和湍流热通量。

In brief, average latent heat, sensible heat and soil heat flux is 40%. 50% and 10% of net radiation respectively.

就平均状况而言，潜热、显热和土壤热通分别占到净辐射的40%、50%和10%。

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 flux of evapotranspiration and turbulent heat exchange are 86.2% of the net radiation of the stand on average. The mean Bowen ratio is 0.5500. The energy consumed by soil heat exchange is 13.4%.

蒸散耗热和湍流热交换占净辐射收入的86.2%，平均波文比为0.5500，土壤热通量约占净辐射收入的13.4%。

The proportion of the soil heat flux under vegetation to slope net radiation: the sunny slope about 16%, the shady slope about 12%, are much more than that of the storing heat of the vegetation to slope net radiation ( < 1%).

植被层下土壤热交换量占净辐射量比例：阳坡约16%，阴坡约12%。

Higher soil heat flux correspond to lower soil water content.

较大土壤热通量对应于较低的土壤水含量。
