| 摘 要： | 桉树试验林样本分析结果表明，桉树树杆中氮，磷，钾养分浓度的倒数与养分吸收量早明显的负线性相关。基于这一相关性，对实测的数据作回归分析。估测的立地生产力极限和养分生产力参数值，以及相应的立地养分效应曲线具有较高的精确度。本文为研究林木生长和营养的动态函数关系提供了新的思路和方法。

| Abstract: | Correlation analysis was conducted using stem samples collected from Eucalyptus trial stands. A negative linear correlation between the reciprocal of nutrient concentration and the total amount of nutrient uptake in tree stem was observed for the three tested elements, nitrogen, phosphorus and potassium. Based on this linear relationship, the site productivity potential and the nutrient productivity parameter, as well as the site & nutrient effect curves were determined using the measured data with relatively high level of accuracy. The present study provides a new way for approach to the dynamic functional relationship between forest growth and nutrition. |
