伊犁河流域土壤重金属含量空间分布及其环境现状研究
Study of Spatial Distribution of Heavy Metal Elements Content and Its Environment Status in the Ili River Valley Region
摘要
Abstract
In this paper,the Ili River valley region as a study area,the heavy metal elements such as Cu,Pb,As and Hg content in 103 soil samples were measured to analyze spatial distribution of Cu,Pb,As and Hg by geostatistical analysis.The results indicated that Cu,Pb,As content in the soil were significantly higher than the background value of soil in Xinjiang,and Hg content was opposite.The heavy metal in the soil of the study area exhibited variability at different degree,which As in the soil sample exhibited the largest variation degree.Spatial analysis indicated that Cu,As,Hg content in the soil samples was moderate spatial correlation,which were affected by the dual influence of random factor and structure factor.As content in the soil had the most influence on random factor,and Pb was strong spatial correlation,mainly influenced by the structure factor.The Nemerow index evaluation method was used to evaluate environmental pollution caused by Cu,Pb,As and Hg in the soil.The results showed that the soil in the studied region was not polluted by Hg.Overall,the soil in the studied region was polluted by Cu and Pb moderately,but the degree of pollution was less in some survey areas.The soil was polluted heavily by As,especially pollution phenomenon in Huocheng county,Yining county,Yining city and Qapqal county.关键词
