郓城县北部地区土壤元素地球化学背景值特征
Characteristics of Geochemical Background Value of Soil Elements in Northern Yuncheng County
摘要
Abstract
Taking the surface soil of Yuncheng county as the research object,the content data of 26 soil in-dexes have been obtained through a systematic geochemical survey.Geochemical parameters,such as the background values of elements in the soil have been calculated.On this basis,the accumulation trend of heavy metal elements in Shandong Province has been studied by comparing with geochemical survey data of more than 1∶250000 target areas in 2003.A study has been conducted on the accumulation trend of heavy metal elements in the area.A single period incremental model has been used to predict the content of heavy metal elements in soil in 2035.Comparing with the average background values of soil in Shandong prov-ince,the elements in the soil of the study area that are significantly higher are B,1,organic matter,N,As,S,MgO,Cd,P,CaO.From 2003 to 2019,the heavy metal elements,such as Hg,Cr,Pb and Cd in the study area are increasing,while As element is slightly decreasing.It is predicted that the environmen-tal quality of Cd element in the study area will decrease significantly by 2035.It should be given sufficient attention.关键词
