摘　　要：采用布点区采样与室内分析相结合的方法,对硼砂生产厂区自然修复状态下的土壤影响因素含量测定,考察土壤影响因素的改变,分析生产过程中影响因素迁移可能发生的污染。结果表明:碳碱解车间和精制车间不同取样深度硼含量差异较大,pH值处于碱性,两者垂直地下方向均呈现低-高-低走向趋势,办公区对照点土壤受到一定程度的污染,宿舍区对照点硼含量、土壤pH值与当地土壤状况一致。杂填土及生产原料所含有的重金属、硼、碱性物等污染物通过自身重力垂直向下迁移,有污染土壤及地下水环境的风险。The determination of the content of soil influencing factors in the natural restoration state of the borax production plant area is carried out using a combination of point sampling and indoor analysis.The results indicate that there are significant differences in boron content of the carbon alkaline hydrolysis workshop and the refining workshop for different sampling depths.When the pH value of the soil is alkaline,both vertical underground directions show a low high low trend,and the soil in the office area is also polluted to a certain extent.The boron content and soil pH value at the control point in the dormitory area are consistent with the local soil pH value.The pollutants such as heavy metals,boron,and alkaline substances contained in miscellaneous fill and production materials migrate vertically downwards through their own gravity,which poses a certain risk of soil and groundwater environmental pollution.
