摘要
包头市西南全巴图工业污水排放地区,在水文地质、气候等因素综合作用下,形成以草甸盐土为主的盐渍土,土壤中含盐量0.32～19.02％,是中度-强度盐渍化土或盐土,盐害较重,在进行改良后才能利用。盐土盐分以表层最高,土层中下部浓度变低,尤其改良地淡化过程明显(表3)。在本区盐渍土地上,采取合理的改良措施后,可以逐步地进行防污林带营造等保护生态环境的工程。
Bautou city the south-west the chanbatu area is where industrial dischages place. It is acted on hydrogeology and climate to take place meadow solonchak for the morsterpart saline soil. In soil salinity content 0. 32%-19. 02%. That is middle to intensity saline soiland solonchak,salt virulaces are massiveer. After will be modilied saltierra. It can utilize. Salinity at superficial coat are highter in solonchak,Below levels salinity is low,particularly was modified solum,where is obvious weakprocess. At saltierra after by means of cukurious modilied means,it may step-by-step todo build forest engineering ecological environmetal protection.
