| 摘 要： | 在分析河南黄淮平原土壤和小麦籽实中Cu含量分布特征的基础上，利用单项污染指数法对研究区小麦籽实中Cu的污染状况进行评价。其结果为：研究区小麦籽实中Cu的单项污染指数Pi的平均值为0．473，说明研究区小麦籽实未受Cu的污染。Cu的状况良好。进一步讨论了土壤中Cu的含量与小麦籽实中Cu含量间的关系。认为小麦籽实中Cu的积累与土壤中的总Cu无明显的相关关系，而与土壤中的有效态Cu含量具有明显的相关性。据此，将土壤有效态Cu作为土壤Cu生态安全评价的指标。并建立了小麦籽实Cu与土壤有效Cu的响应关系模型，确定了土壤中有效Cu的安全界限值。 |

| Abstract: | On the basis of an analysis of the distribution characteristics of the Cu content in softs and wheat seeds in the Huanghuai plain, Henan, the Cu pollution in wheat seeds in the study area is evaluated by using the monomial pollution index. The results show that the average monomial Cu pollution index P, of wheat seeds in this area is 0.473, suggesting that the wheat seeds in this area have not been polluted by Cu. The authors also analyze the relation between the Cu content in softs and that in wheat seeds and think that the cumulative Cu content in wheat seeds has no significant correlation with the total Cu content in softs but shows a significant correlation with the effective Cu content in softs. So the authors use effective Cu in softs as the index of ecological security evaluation of Cu in softs to construct a model of response relationships between Cu in wheat seeds and effective Cu in softs and determine the security limit of effective Cu in softs. |
