摘要:
 采用时空互代法，以流沙地为对照，研究毛乌素沙地不同林龄樟子松人工林土壤酶活性随栽植年限的变化特征，并分析土壤酶活性与土壤养分的相关性及土壤酶指数。结果表明：随着林龄的增加，土壤蔗糖酶、过氧化氢酶、碱性磷酸酶、脲酶活性均增大，到32 a时达到最大，分别是CK的5.38、2.24、3.07、3.22倍；而多酚氧化酶活性则随林龄增加而减小，到32 a时酶活性达到最低，仅占CK的16%；相关性分析表明，蔗糖酶、过氧化氢酶、碱性磷酸酶、脲酶和多酚氧化酶不仅与土壤养分因子相关性较强，相互之间也呈极显著相关性，可以作为土壤质量评价的生物学指标；土壤酶指数(SEI)作为土壤酶活性的综合表征，可以全面的反映土壤酶活性随林龄的变化特征，能够作为一种土壤质量评价方法。
Abstract:
 In order to understand the effects of Pinus sytvestris var. mongolica plantation at different ages on soil enzyme activity, five kinds of soil enzyme (sucrase, urease, phosphatases, catalase, polyphenol oxidase) activities, the relationship between soil enzyme and nutrients and soil enzyme index in Muus Sandland were studied by using the method of time-space mutual substitution. The results showed that sucrase, catalase, phosphatases and urease activities in the soil increased significantly with the increase of stand ages. After 32 years, the soil enzyme activities reached the maximum, which were 5.38, 2.24, 3.07, 3.22 times respectively compared to the control. However, polyphenol oxidase decreased by 16% compared to the control after 32 years. The significant correlationships were observed between soil enzyme activities and nutrient factors. Therefore the enzymes could be used as good biological indicators in evaluating soil quality. The soil enzyme index could indicate the evolution of soil enzyme activities with the increase of stand ages and could be used as a way to assess soil quality.
