内蒙古沙漠盐沼湿地生态环境特征研究

Study on ecological environment characteristics of desert salina wetland in Inner Mongolia

对内蒙古沙漠盐沼湿地的生态环境特征进行连续多年的研究,结果表明,内蒙古沙漠盐沼湿地生态环境因子特征是高盐、高碳酸盐碱度、高硬度、高离子系数(M/D)值,低Ca2+/Mg2+、低Ca2+浓度。在盐沼湿地水体中,Ca2+是特别重要的影响因子,其含量反映盐沼湿地生态环境的水质特性。盐沼湿地生态环境分析中,在对盐度、碳酸盐碱度(CA)、总硬度进行分析的基础上,M/D和Ca2+/Mg2+是重要的不可忽略的特征生态指标。

Ecological characteristics of desert saline wetland in Inner Mongolia were studied for many years. The result showed that, the ecological environment was characterized by high salt, high carbonate alkalinity, high hardness, high M/D value, low Ca^2＋/Mg^2＋ value and low Ca^2＋ concentration in Inner Mongolia desert salina wetland. In salina wetland water, Ca^2＋ concentration was a particularly important impact factor, reflecting the water quality characteristics of saline wetland ecological environment. In the analysis on the saline wetland ecological environment, on the basis of salinity, CA, total hardness, M/D value and Ca2＋/Mg^＋ value were characteristic indicators that could not be ignored in ecological environment.
