| 摘 要： | 研究了千烟洲试验区马尾松人工林凋落叶及其Ｎ、Ｐ、Ｋ、Ｃａ、Ｍｇ、Ａｌ、Ｍｎ、Ｎａ、Ｆｅ、Ｂａ、Ｓｉ、Ｚｎ等１２种营养元素的数量动态变化。对该树种的凋落叶数量的分析，表明该树种的凋落叶在１年中各个时期具有不同的特征，同时还可以看到凋落叶的养分元素月积累量亦随着季节的不同出现高峰和低谷，从而进一步加深了解凋落叶在森林中的功能地位。

| Abstract: | This paper studied withered leaves of artificial forest of masson pine and their quantity dynamic change of N,P,K,Ca,Mg,Al,Fe,Na,Mn,Ba,Si and Zn,totally 12 nutrient elements in the experimental plot of Qianyanzhou Station in Jiangxi Province.It showed that the mineral elements in the withered litters varied with the seasons,these might be helpful for the further understanding of the functional position of dropped leaves in forest. |
