Adjusting and storing function of pine-cypress stand to soil infiltration.

Since the infiltration capacity curve in a single testing plot can't show the adjusting and transforming function of forest soil system to runoff amount of earth surface under different scales, this paper used hydrologic analysing method to study the soil infiltration rules of slope runoff site and obtain the average infiltration parameter of comparatively large areas, and then this parameter can be used to calculate the run_off amount of earth surface and it's process under different scales.
