摘 要 ：本试验地是在杉木林和马尾松林中,主要对降雨和径流水中所含各种养分物质进行测定。结果表明:降雨的养分含量与降雨量存在着半对数函数关系。降雨输入林地的养分量显著地大于径流输出的养分量。林内雨和树干茎流淋溶的养分量占养分还原总量的48—53％。林内雨和树干淋溶的K、Mg、N养分物质量超过凋落物归还养分量。

Abstract: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 tra...
