摘　　要：通过对研究区6种不同利用模式下土壤养分指标的测定,对比分析出各利用模式间土壤养分含量水平和差异显著性。结果表明:不同的风沙土利用模式下土壤养分含量差异明显,美国扁杏+麻黄草模式土壤各养分指标的含量较高,表现出最好的土壤养分特征;而无防护林花生地的土壤则较贫瘠,养分含量最低。表明经过人为治理过的风沙地土壤养分含量比未治理的风沙地明显提高。Soil nutrient index of 6 different utilization patterns in research area was measured. Significance of difference and soil nutrient level in different utilization patterns were comparatively analyzed. The results showed that soil nutrient content had significant difference under different utilization patterns of aeolian sandy soils. The pattern of America apricot ＋ grass ephedra had higher soil nutrient index, and showed the best soil nutrient characteristics. But soil in non-protective forest peanut land was relatively barren and had lowest nutrient content. Aeolian sandy soil with artificial treatment had higher nutrient content than that with non-artificial treatment.
