| 摘 要： | 根据42个土壤剖面，225个土壤样品，58个水样的分析结果，讨论了额济纳三角洲地区土壤的基本特征，并研究了土壤盐分分布规律以及与地形地貌部位、地下水水化学的关系。结果表明：额济纳三角洲地区的土壤具有质地粗、含盐量高，盐分表聚性强的特征；在所有剖面上盐分的分布呈现漏斗型分布，土壤中盐分随地形变化较为复杂，但与地下水化学类型一致。

| Abstract: | According to the analysis result of 42 soil sections, 225 soil samples and 58 water samples, the soil characters in Ejin delta was discussed. Simultaneously, the soil salinity distributing features and its relationship with landform and groundwater chemistry were analyzed. It was concluded that the soil of Ejin delta has coarse texture, high salinity and even surface assembled. The salinity in all sections appeared infundibular distribution. Although the soil salinity varied complicated with terrains, it was consistent with groundwater chemistry type. |
