| 摘 要： | 由于污灌方式、土壤质地等因素的影响，污灌土壤的污染程度可能具有较明显的空间差异。因此，传统的土壤环境质量评价方法难以准确反映土壤的环境质量。本文应用克立格方法对北京东郊污灌土壤表层重金属含量进行了分析，并在此基础上进行了单因子和多因子评价。结果显示，采样区的土壤属于轻度污染或无污染。由于污灌口分布、污泥施用等多种因素的影响，不同地块土壤受到的污染程度不同，形成一定的空间差异。

| Abstract: | Due to the effects of wastewater irrigation and soil characteristics,the pollution situation of wastewater irrigated soil may be varied in space;therefore,the traditional methods are not good enough in soil environmental quality assessment.In this paper,kriging method was used in assessing the heavy metal pollution in soil from eastern suburb in Beijing area.Results showed that of the soil was polluted by heavy metal and the pollution situation varied in space significantly. |
