摘要： 土-水分配系数（Kd）是表征重金属污染物在土壤包气带中迁移能力的重要参数，受污染物质量浓度、pH值、有机质质量分数、铁铝氧化物质量分数等多种因素影响。本文通过实验研究了分配系数与各种影响因素之间的关系，基于多元回归分析方法得到了分配系数与影响因素的关系方程；并以分配系数、泄漏量、土壤孔隙度、初始含水率为风险因子建立了地下水污染风险评价方法。以某工厂铬废液的泄露为案例，采用构建的方法进行地下水污染风险评价。结果表明：该处地下水被污染的风险等级为中等。地下水污染风险评价方法的建立为重金属污染地下水的监测管理提供了一种有效方法。

关键词: 多元回归分析, 六价铬, 分配系数, 地下水, 风险评价

Abstract: Soil-water distribution coefficient (Kd) is an important parameter to characterize the migration of heavy metal pollutants in the vadose zone,Kdof Cr(Ⅵ) is influenced by the concentration of pollutants, pH value, organic matter content, iron oxide content, aluminum oxide content and other factors.The relationship between Kd and influence factors was investigated by experiment.Based on the multiple regression analysis method,relation equation between the distribution coefficient and various factors was obtained, and the risk assessment method of groundwater pollution was established with the distribution coefficient, leakage, soil porosity, initial water content as risk factors. With the case of chromium waste liquid leakage, pollution risk assessment of groundwater was carried out based on established method. The results show that the risk level of groundwater contamination is moderate. The establishment of groundwater pollution risk assessment method provides a method for management of contaminated groundwater by heavy metal.

Key words: multiple regression analysis, Cr(Ⅵ), distribution coefficient, groundwater, risk assessment
