| 摘要: |
| 通过对新疆阿克苏农一师北二干3.33万hm2盐碱荒地的调查及不同深度剖面土样的分析，研究了该地区土壤的系统分类，根据《中国土壤系统分类检索（第3版）》，鉴定了诊断层和相关诊断特性。结果表明，该地0～15 cm土壤中总盐含量>20 g/kg，pH<8.5，ESP<30％，结合土壤的机械组成，可确定该地区的土壤为普通干旱正常盐成土。 |

| Abstract: |
| This study aimed to examine the physical and chemical properties of 33 300 hm2 saline alkali soil in Aksu area,Xinjiang Uygur Autonomeus Region.Diagnostic layer and diagnostic characteristics were identified according to Chinese Soil Taxonomy (3rd edition).Results showed that the total salinity was greater than 20 g/kg in 0～15 cm layer,indicating a salic horizon.The pH of this layer was less than 8.5 and ESP was less than 30%,meaning that the layer was not alkaline.Mechanical composition showed differences in the distribution of sandy,slit and clay.Through the analysis of the soil profile,this soil should be characterized as a Typ-Ari-Orthic Halosols. |
