| 摘 要： | 土壤地球化学基准值是指未受人为污染的,反映土壤原始沉积环境的地球化学元素含量;是反映土壤地球化学特征的基本指标,也是制订环境质量标准,识别和评价土壤污染程度,确立污染治理修复目标的重要依据。文章对广东韶关地区1023件深层土壤样中54项元素(指标)含量进行了分析研究,并与地壳丰度、中国土壤C层元素含量(仅13项指标)、广东省C层土壤元素含量进行了对比。结果表明,区内土壤中与酸性岩浆岩、砂页岩、成矿作用相关的元素基准值较高,与基性岩、碳酸盐岩组成相关的元素基准值较低,其元素组合反映了该区土壤的中酸性的地球化学特征。对研究区主要成土母质地球化学基准值的研究表明,土壤元素地球化学基准值继承了成土母岩母质的元素地球化学特征,不同成土母质类型的土壤地球化学基准值差异较大。

| Abstract: | Geochemical reference value is the basic index to reflect the characteristics of soil geochemistry,and it is an important basis for formulating environmental quality standards,identifying and evaluating the degree of soil pollution,and establishing the goal of pollution control and remediation.To better carry out research in the fields of environmental protection,land,agriculture and health in Shaoguan area of Guangdong Province,the contents of 54 elements(indicators)in 1023 deep soil samples were analyzed and compared with crustal abundance,Chinese soil C layer element content(only 13 indexes)and Guangdong C layer soil element content.The results show that the element reference value of Shaoguan area related to acid magmatic rocks,sand shale and mineralization are higher,while the element reference value related to basic rocks and carbonate rocks are lower.The combination of elements reflects the intermediate-acid geochemical characteristics of the soil in this area.The study on the geochemical reference values of the main parent material in the study area shows that the parent material type of the soil has a certain influence on the soil geochemical reference values,because the soil geochemical reference values of different parent material types vary greatly.The soil element geochemical reference value inherits the elemental geochemical characteristics of parent materials. |
