塔里木盆地潮湿冲积新成土形成特点

Formation Characteristics of Aqu-Alluvic Entisols in Tarim Basin

干旱内陆地区的潮湿冲积新成土主要位于大河两岸的河滩地 ,它的地下水位高 ,土壤水分为潮湿状态。受到洪水的影响 ,虽然盐分已具有表聚 ,但缺乏盐结皮层。由于不断有新的泥沙沉积物加入 ,土壤无明显发育 。

Aqu-Alluvic Entisols was located in the flood land of river in arid inland area. The ground water table of the soil is high and soil moisture regime is aquic. Although salt had begun to accumulate in soil surface, there was no salic crust horizon in its surface. As new sediment was often inputted to soil surface, soil developing process was not obvious, its property is affected by soil texture to a great degree.
