摘 要 ：马尾松天然林随年龄生长过程的生物量及养分积累分布进行研究，结果表明：12—31年生林分中，25年生林分生产力最高，为9.07t/hm²;树叶中养分含量以21年生最高，表明此时林分正在生理旺盛期; Ca主要积累于树皮中;每生产1t干物质，12年生林分需大量元素3.763kg，21年生林分需4.695kg。

Abstract:The results showed that in 12 to 31-year-old Pinus massoniana forests，the produc-tivity of 25-year-old forest in the highest,which is 9.07t/hm²．The nutrient content in leaves of 21-year-old forest is the largest，which indicated that the forest is of physio-logical exuberance．Ca accumulates mainly in the bark．The requirement of nutrient ele-ments to produce one ton dry biomass is 3.0763kg and 4.695kg for 12-and 21-year-old forest respectively．
