摘　　要：通过对枸杞园土壤中铜含量的调查分析,探讨了枸杞园土壤中铜的空间变异特征。结果表明,随着枸杞种植年限的延长,枸杞园土壤有效铜和全量铜含量明显增加;随着土层深度的增加,枸杞园土壤有效铜以及全量铜含量呈现下降的趋势。说明,随着种植年限的增加,枸杞园土壤铜有累计增加的风险。spatial variability characteristics of soil copper in Chinese wolfberry were discussed in this paper though research and analysis on soil copper content in Chinese wolfberry. The results showed that both effective copper and total copper contents in Chinese wolfberry fields increased obviously with increasing planting years, while those contents decreased with increasing soil depth. The results indicated that soil copper in Chinese wolfberry fields are inclined to increase with increas- ing planting time.

关 键 词：土壤 枸杞园 有效铜含量 全量铜含量 空间变异性
