| 摘 要： | 研究表明,闽东南滨海盐土含盐量的变化,与土壤粘粒呈显著的正相关,r_(0.05)=0.6768;其盐分组成中阳离子以 Na~+为主,阴离子以 Cl~-为主。滨海盐土一经开发利用,其盐分含量及其离子的消长规律,以 NaCl 消失最快,HCO_3~-相对升高较明显,这似可作为滨海盐土熟化的标志之一。

| Abstract: | The study shows significant positive correlation(r_(0.05)=0.6768)bet- ween salt content and clay of saline soil in the coastal area of south-eastern Fujian.Studies on salt composition have shown that Na~+ is the main cation and Cl~-is the main anion.When the coastal saline soils were reclaimed and utilized,the tendency of salt cotent and the ions existed had shown that Na~+ was disappeared earlies while HCO_3~-increased.It seems to be one of the characteristics of well developed saline soils in the coastal area. |
