采用灰色系统理论，对高阿丁枫人工林土壤肥力定位监测结果进行分析，得知：高阿丁枫人工林的土壤养分含量１９９３～１９９５年呈下降趋势，１９９５～１９９８年有所回升，但总的变化趋势是下降。其中，土壤有机质含量呈上升状态，有效Ｎ含量变化平稳，稍有上升，全Ｎ、有效Ｐ、有效Ｋ则呈下降趋势。因此，高阿丁枫人工林土壤养分含量下降的原因是土壤全Ｎ、有效Ｐ、有效Ｋ呈下降趋势。在高阿丁枫营林生产中，应考虑补充土壤中的Ｎ、Ｐ、Ｋ。
Based on the gray system theory, the results of soil fertility monitoring in the high-afforestation plantation were studied. The results showed that the soil nutrient contents of the high-afforestation plantation decreased from 1993 to 1995, but rose from 1995 to 1998, The overall trend is declining. Among them, the content of soil organic matter increased, the content of available N changed steadily and slightly, and N, P and K decreased. Therefore, the reason for the decrease of soil nutrient content in Artificial Altingia excelsum is that the soil total N, available P and available K decrease. In the high-affluence forest production, should consider adding N, P, K in soil.
