| 摘 要： | 从中角度研究了国家级保护植物粘木不同顺官和土壤中氮、磷、钾、钙、锌５种元素的分布和循环，研究结果表明：（１）土壤中的Ｎ和有机质含量丰富，磷的贮量则较大于多数热带林：Ｃ：Ｎ比率接近１０，显示着森林处于不稳定状态。（２）营养元素在不同成熟阶段的叶中是不同的；幼叶和较成熟叶具较高的Ｎ、Ｐ、Ｋ；而叶和老叶则食较高的Ｃａ和Ｍｇ。（３）不同成熟 叶中，Ｎ：Ｐ比具有重要意义，Ｎ：Ｐ：比对于反映Ｐ的供应是一个很好 |
| 关 键 词： | 常绿阔叶林 营养元素 分布 循环 |

| Abstract: | Studied nutrient distribution,nutrient storage,and annual nutrients uptake in different parts of trees and concluded that nutrients vary in leaves of different mature state and in bark and wood.Internal cycling of N,P,K indicates the conservation recycling of these nutrients.Large amount of nutrients stored in this population indicate which play an important role in the forest.The turnover time of N,P,K,Ca,Mg in the population is 12 1,13 1,18 8,12 2 and 19 04 year respectively. |
| Keywords: | broad leaf evergreen forests nutrient storage and cycling |
