| 摘 要： | 本文是1980--1983年本所湖南会同森林生态实验站成年杉木纯林中进行定位研究根据所取得的观测资料，分析和论述了营养元素在林内的积累与分配；以及从降雨中的输入量，计算了营养元素的年吸收量和归还量。研究表明，杉木纯林在21--23年生时，即达到主伐年龄期，营养元素年吸收量仍大于归还量，整个林分还处在养分消耗阶段。

| Abstract: | The accumulation, distribution and cycling of nutrient, elements were studied in a mature (21–23 yr. old)and pure stand of Cunninghamia lanceolata in Huitong County of Hunan Province, during 1980–1983. The results are summarized as follows: 1. Concentration of nutrient elements in organs of the C. lanceolata tends toward Ca>Mg>N>K>P. The highest concentrations of nutrient elements were found in the leaf and the lowest in the trunk. 2. Total accumulations of nutrient elements of tree layer, understorey layer and ground-cover layer were estimated to be 1993.83kg/ha, 34.46kg/ha and 166.91kg/ha respectively. Total accumulations of nutrient elements in one ton of standing crop were in the order of tree layer< understorey layer
