| 摘 要： | 本项研究历时４年，研究结果显示，营造蓝桉纯林会引起林地土壤肥力明显降低，有机质、全Ｎ、有效Ｎ、Ｐ、Ｋ、交换性Ｃａ２＋、Ｍｇ２＋等７项指标均直接受影响。蓝桉人工林，经造林初期林地施肥能提高其生长量，但不能阻止林地土壤肥力下降。由于施肥促进了林木的生长，故也加强了对土壤肥力的消耗。

| Abstract: | Results of 4 years study on soil fertility of Eucalyptus globulus plantation indicate that con-struction of Eucalyptus globulus will cause obvious decrease of soil fertility.7 items of indexes, that is organic matter, whole N, available N, P, K and exchangeable Ca 2 , Mg 2 will be affected. Fertilizer application increase the increment of Eucalyptus globulus plantation with the decrease of soil fertility.Vi-gorous growth promoted by fertilizer also consume soil fertility to a great extent. |
