Plants take carbon dioxide out of the atmosphere, but they also have other effects, such as changing the amount of evaporation from the land surface.

虽然作物将二氧化碳释放到空气中，但是他们仍有其他影响，例如改变其在土壤表面的蒸发量。

Compared with the bare land, the mixed forest and manual shrubbery can reduce evaporation from water surface 50.54% and 55.20%, respectively.

水面蒸发量为裸地最大，混交林及灌木林能有效减少水面蒸发，减少量较对照裸地可达50.54%和55.20%。

The amount of evapotranspiration of farm land can be calculated by multiplying the largest possible evaporation capacity of water surface with a special coefficient.

用它计算的水面最大可能蒸发量乘以一定系数，便可换算成农田蒸散量。
