Abstract This paper uses the systematic theory to study forest eco-system's function on adjustment and exchange of rainfall and runoff,and starts with single factor to show the independent role of each factor in water and eco-system in the fields.The author applies the results to study the synthetic effects and the final responds with the scale enlargement in watershed,hence implies the adjustment and exchange rule of rainfall and runoff after forest systematic coupling.
