孔雀河流域包头湖农场地下水质量评价

Assessment of Groundwater Quality and Pollution in Baotouhu Farm of Kongque River Basin

采用单指标法对孔雀河流域包头湖农场地下水质量进行了评价。结果表明:地下水水质整体偏差,且由北至南逐渐变差;潜水水质均为Ⅴ类,矿化度在10 g/L以上,不适宜饮用,且引起了土壤次生盐渍化问题;包头湖农场区域内的孔雀河段,接近上游部分的深层地下水水质比下游的要好,处于河段下游的水质较差且矿化度较高。通过分析影响地下水质量的自然因素和人为因素,提出了改善包头湖农场地下水水质的建议,包括防止地下水受农业活动污染、合理开发地下水、合理处置废弃设备等。

Using the single index method to evaluate the groundwater quality of Baotouhu Farm in Kongque River basin. The results show that the groundwater quality is poor in total,and groundwater quality deteriorates from north to south( downstream along the Kongque River),gradually; shallow groundwater quality is class Ⅴ,the salinity is above 10 g / L,which is not suitable for drinking and causes serious soil salinization problems. For the section of Kongque River in Baotouhu Farm area,the deep groundwater quality of the upper part is better relatively to the downstream and the salinity is high. Through analyzing the natural factors and human factors that affected groundwater quality,it puts forward suggestions to improve the groundwater quality of Baotouhu Farm. The suggestions include preventing groundwater polluted by agricultural activities,reasonable exploitation of the groundwater and reasonable disposition of the obsolete equipment.
