工业污染区盐渍土水盐动态的研究——以包头西郊全巴图地区为例

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，并讨论了式

WATER AND SALT MOVEMENT OF POLLUTED SOIL IN THE SUBURB OF BAOTOU CITY

The paper,through field investment,sampling and laboratory measurement,deals with soil water and salt movement in the polluted area of Baotou City.The results show that it is obvious that soil salts collect in the surface layer,the salt content is from 0.32% to 19.02%.the mineralization degree is between 2.9 and 20.6 g/l;the studied soil is defined mid strong salinized meadow soil.The paper try to reveal the soil water and salt movement regime,and proposes effective ways to harness the salt affected soil and to regenerate the ecologic environment.
