摘要：考虑到依据现行土壤环境质量标准(GB15618-1995)的土壤污染评价过程中存在较大的不确定性,将灰色理论引入土壤环境重金属的污染评价中,提出了基于灰色关联度的土壤环境重金属污染综合评价法.将灰色综合评价法应用于现实的案例土壤重金属的污染评价中,结果表明案例区域土壤重金属的8个采样点中只有S1为Ⅲ类土壤,其它样点均为Ⅰ类土壤.灰色综合评价法减少了在土壤污染综合评价中的主观人为因素,并可同时表征同一采样点不同级别和同一级别不同样点之间的土壤环境质量差异,并且在实例研究中发现其可提高预算的有效使用率,是一种可行的评价方法.
On the basis of the study on shortcomings of the certain assessing method based on the Chinese criterion of soil quality（GB15618-1995）,an integrated model for assessing the pollution level of soil heavy metals was developed based on grey correlation theory.To test and verify this integrated model,a contaminated site was assessed by it.The result showed that sample site 1（S1） was on soil quality level Ⅲ,and other 7 sample sites belonging to soil quality level Ⅰ.This integrated grey assessing method was with higher discernibility by reducing influence factors of people and carrying comprehensive information of soil heavy metals pollution which could give scientific reference to reducing unnecessary cost.
