摘要: 松嫩平原西部盐沼湿地水环境碱化程度高,水中的pH值普遍高于8.0,多数为苏打钠型水。在对本区盐沼基本水环境化学特征阐述的基础上,通过对水化学的基本变量CO32-、HCO32-、Cl-、Ca2+、Mg2+、SO42-、Na+和派生变量(Cl-+SO42-)/HCO32-及Na+/(Ca2+ Mg2+)等的相关分析,得出各水化学变量之间的相关关系,并以pH值为分类基础得到了判别函数和判别区域图,对区域盐沼湿地水环境化学特征的研究方法作出了有意义的尝试。

关键词: 盐沼湿地, 水化学特征, 相关分析, 判别分析

Abstract: In the west of Songnen Plain, the saline-alkali degree is high in saline water-body and marsh where pH value is generally over 8 0, and the chemical type of water is HCO32- -Na+. Through analysis on the basic saline-alkali variables such as O32-, HCO32-, Cl-, Ca2+, Mg2+, SO42-, Na+ etc. and the composed variables such as (Cl-+SO42-)/HCO32- and Na+/(Ca2++Mg2+), the relationships between different variables were found, and the discriminating function and critical region map were got basing on the pH value, by which the significant study method on saline-alkali water-body was attempted.

Key words: salt marsh, chemical characteristics of water, correlation analysis, discriminatory analysis
