摘 要 ：对12年生黧蒴栲林9种营养元素的积累、分布进行研究，结果表明：该林分大量元素的年均积累量为81.59kg/hm²·a，其中K占51.5％，N占31.6％，微量元素为2.756kg/hm²·a，其中Fe占53.6％，Mn占38.7％；叶片中大量元素的积累量均高于其它器官；每生产lt干物质需大量元素10.25kg，微量元素346.2g。

Abstract:The accumulation and distribution of nutrient elements in a 12-year-old Castanopsis fissa plantation was studied．The results showed that the net-accumulation of nutrient elements is 81.59kg/hm²·a，in which K is 51.5％and N is 31.6％．Net-accumulation of mieronutrients is 2.756kg/hm²·a，in which Fe is 53.6％and Mn is 38.7％．The net-ac-cumulation of nutrient elements in leaves is higher than that in other organs．The re- quirement to produce one ten dry biomass is 10.25kg for nutrient elements and 346.2g for micronutrients．
