通过野外调查,定位采样及室内测定,研究了包头西郊工业污染区土壤水盐动态,结果表明:该地区地下水矿化度在2.9~20.6g/L之间,水化学类型为Cl-+SO=4-Na++Mg++和Cl-+HCO=3-Na++Mg++型,在植物生长季地下水位有两个高值期和一个低值期。表层土壤含盐量在0.32%~19.23%之间。土壤盐分在剖面的分布呈漏斗型,在时间上的变化与地下水位大体一致。并讨论了工业污染区盐渍化土地的改良途径。
The field water and salt dynamics in the industrial pollution area in the western suburbs of Baotou were studied by field investigation, location sampling and indoor measurements. The results showed that the salinity of groundwater in the area was between 2.9 ~ 20.6g / L and the hydrochemical type was Cl - + SO = 4-Na ++ Mg ++ and Cl- + HCO = 3-Na ++ Mg ++. There are two periods of high and one period of low water level in the plant growth season. Surface soil salinity between 0.32% ~ 19.23%. The distribution of soil salinity in the profile is funnel-shaped, and the change in time is generally in accordance with the groundwater level. And discussed the improvement of salinized land in industrial pollution area.
