| 摘 要： | 目的]研究桉树一甘蔗复合系统土壤的化学性状及酶活性。为桉树林农复合经营提供理论参考和技术支持。方法]以林带为对照，研究间作带不同位置土壤化学性状及酶活性的变化。结果]结果表明，土壤化学性状及酶活性随土层深度增加而降低（土壤pH值除外），土壤养分主要集中在0～20cm土层。与林带相比，间作带（距林带3．0、4．5、6．0m处）土壤养分均有不同程度地提高；但距林带3．0m处的提高幅度较小，部分指标呈现出下降趋势，这可能与人为因素、林木根系与作物的养分竞争等原因有关。结论]总体上，实行桉树林农复合经营，间作带土壤化学性状得到了改良，酶活性也有改善，这为下一轮伐期桉树的生长创造了有利条件。
