With the help of a natural watershed, in which the vegetation was the artificial forest of Pinus massoniana with a 10 years old, it had been studied for the hydrological process and the movement of mineral elements. The evaporation in the stand was 4.0% of the annual rainfall, interception 20.8%, runoff 27.8%, throughfall 76.5% and stemfall 2.7%. It was the most concentration of K,P,Ca,Mg, Zn,Cu,Fe and Mn in the throughfall, the surplus of 8 mineral elements in the watershed was 8.528 kg/h㎡ in the average from 1993 to 1994.
