摘要/Abstract

摘要： 为分析比较回归模型法(RM)和物种敏感性分布法(SSD)在推导云南个旧某渣场农用地铅镉有效态安
全阈值方面的适用性,以渣场周边农用地土壤为对象,通过盆栽试验,探究小白菜重金属含量对污染土壤中铅镉含量
的响应关系,采用RM 法和SSD 法推导农用地土壤Cd 和Pb 有效态安全阈值,进行分析比较。结果表明:土壤中Cd
和Pb 的全量和有效态含量均与小白菜中Cd 和Pb 含量呈正相关,土壤和小白菜中Cd 和Pb 有效态含量与pH 呈显著
负相关,与有机质和阳离子交换量呈正相关。RM 法推导出土壤中Cd 和Pb 有效态阈值分别为0. 68 和204. 8 mg/ kg,
SSD 法推导求出土壤Cd 和Pb 有效态阈值分别为2. 02 和388. 60 mg/ kg。采用RM 法推导的有效态阈值判断,农用地
土壤中Cd 和Pb 有效态含量全部位于A、D 和F 区域内,即土壤不超标且小白菜不超标以及土壤超标且小白菜超标的
区域,正确率较高。运用SSD 法推导求出有效态阈值判断,土壤中Cd 和Pb 有效态含量位于D 和F 区域内,即土壤不
超标而小白菜超标以及土壤超标且小白菜超标的区域,正确率较低。故RM 法推导的有效态安全阈值更能反映云南
个旧某渣场周边农用地土壤Cd 和Pb 有效态含量的实际情况,可为该区域Cd 和Pb 污染农用地土壤修复评价提供借
鉴和指导。

Abstract: To compare the applicability of regression model method (RM) and species sensitivity distribution method
(SSD) in deducing the available concentration safety threshold of Pb and Cd in a slag farm in Gejiu,Yunnan Province. The response
of heavy metal content of Chinese cabbage to Pb and Cd content in polluted soil was investigated by pot experiment. The
available concentration safety thresholds of Cd and Pb in soil of agricultural land were derived by RM method and SSD method
for analysis and comparison. The results showed that the total and available contents of Cd and Pb in soil were positively correlated
with the contents of Cd and Pb in Chinese cabbage,and the available contents of Cd and Pb in soil and Chinese cabbage
were negatively correlated with pH,and positively correlated with organic matter and cation exchange capacity. The available
concentration safety thresholds of Cd and Pb in soil were derived by RM method as 0. 68 and 204. 8 mg/ kg,respectively,while
the available concentration safety thresholds of Cd and Pb in soil were derived by SSD method as 2. 02 and 388. 60 mg/ kg,respectively.
According to the available concentration safety threshold derived by RM method,the available concentration safety
thresholds of Cd and Pb in agricultural soil are all located in regions A,D and F,that is,the regions where the soil does not exceed
the standard and the cabbage does not exceed the standard and the soil exceeds the standard and the cabbage exceeds the standard,and the accuracy is higher. SSD method was used to calculate the available concentration safety threshold judgment,
and the available concentration safety threshold of Cd and Pb in soil was located in the D and F regions,that is,the regions
where the soil did not exceed the standard and the cabbage exceeded the standard and the soil exceeded the standard and the
cabbage exceeded the standard,the accuracy was low. Therefore,the available concentration safety threshold derived by RM
method can better reflect the actual situation of the available concentration safety thresholds of Cd and Pb in soil of agricultural
land around a slag farm in Gejiu,Yunnan Province,and can provide reference and guidance for soil remediation evaluation of
agricultural land polluted by Cd and Pb in this region.
