摘　　要：根据污染损失模型的理论思想和实践应用,结合土壤环境污染的特征,尝试将污染损失率法应用于福州市郊菜区土壤环境质量评价中,并同时计算评价样本的密切值,发现污染损失率法与密切值法的评价结果基本一致,前者表现出对样本中超标较严重的污染因子有更强的分辨率。理论分析和实践应用证明,污染损失率法应用于土壤环境质量评价,物理意义明确,计算过程简便,评价结果合理精确。本研究拓展了污染损失率法的应用领域,也为土壤环境质量评价提供了新的思路和方法。Based on the theoretical and practical application of pollution loss model,with according to the soil pollution characteristics,pollution lost rate method was applied in the environmental quality assessment of vegetables conta minated soil in Fuzhou suburb,the association value of the soil samples were also calculated.The results showed that the assessment conclusions by the two methods were almostly consistent,and the pollution lost rate method manifested more resolving power in the serious pollution index of soil.The soil environment quality assessment application of which showed the explicit physical meanings and simply calculation process,furthermore,the reasonable and accurate evaluation results can also be achieved.The study expands the application areas of pollution loss rate method,as well as the new ideas and methods of the soil environment evaluation quality.
