Abstract
How to scientifically reflect the soil environmental quality of a large area through limited soil point monitoring is a major direction of current research.The Huaihe River Basin in Anhui Province was selected as the study area and soil environmental quality monitoring for five major soil pollution types during five consecutive years was conducted.The monitoring project includes Cd,Hg,As,Pb,Cr,Cu,Zn and Ni in the soil.The single pollution index and Nemerow pollution index methods were used to evaluate 426 monitoring sites.The Kriging interpolation method was used to plot the distribution of heavy metal elements in regional soil.In general,the soil environmental quality of the Anhui section of the Huaihe River Basin is relatively safe according to the evaluation results.96.48% of the surveyed sites belong to clean and relatively clean levels,but some sites were severe. According to the distribution of heavy metal elements in the evaluation area,the overall content is low and the local area is slightly higher.The method of special type monitoring was applied and the characteristics of regional distribution through soil point monitoring results are discussed.The proposed method has great application potential.This method is suitable for preliminary investigation and research of large-scale environmental quality of soil.关键词
