中文摘要:
      分层采集不同时期沧州市滨海盐碱区的土样,采用流动分析仪测定各土样的总含盐量及主要盐分离子,分析土壤的盐渍化特征。结果表明:该地区为硫酸盐氯化物型盐渍化土壤,土壤中氯化钠、氯化镁和氯化钙为氯化物的主要组成部分,硫酸盐类主要为硫酸钠、硫酸镁和硫酸钙。该地区不同采样时期间、不同地区间和不同土层间土壤盐渍化状态均存在极显著差异。除碳酸根+碳酸氢根外,钾离子、钠离子、镁离子、氯离子、钙离子、硅酸根离子和硫酸根离子均为表征该地区土壤盐渍化状态的主要盐分离子。
英文摘要:
      Soil samples from the coastal saline alkali area of Cangzhou were collected in layers in different periods. The total salt content and main salt ions in soil samples were detected by flow analysis. The characteristics of soil salinization were analyzed. The results showed that the soil in this area was salinized by sulfate chloride. The main components of chloride in soil were sodium chloride, magnesium chloride and calcium chloride, and the main sulfate were sodium sulfate, magnesium sulfate and calcium sulfate. There were significant differences in soil salinization among different sampling periods, different regions and different soil layers. Except carbonate + bicarbonate, potassium ion, sodium ion, magnesium ion, chlorine ion, calcium ion, silicate ion and sulfate ion were the main salt ions characterizing soil salinization in this area.
