%X The preliminary study indicates that the nutrient concentration of throughfall has increased obviously in man-made forests of Cunninghamia lanceolata and Pinus massoniana as compared with rainfall in adjacent opening. The relative abundance of nutrient content for precipitation was N>Ca>K>Mg>P. The relative abundance of nutrient content for throughfall was K>N>Ca>Mg>P. The total amount of nutrient input with rainfall in two stands account for 48-53% of total nutrient returns. More amounts of N,K,Mg were transferred to the soil through throughfall than litterfall while more Ca and P were added to the soil through litterfall, Nutrient return approximates precipitation closely in a semi-log curve, indicating a limited and gradual supply of nutrients from their respective sources between the intervals of rain.
