摘要:

土壤污染已成为抑制农业可持续发展的一个重要因素,土壤环境质量与研究区的地质条件、自然物理化学条件和人类活动有关。以河套地区多目标区域地球化学调查取得的表层土壤元素资料为依据,参照《土壤环境质量标准》(GB15618—1995)中As、Cd、Cr、Cu、Hg、Ni、Pb、Zn分级标准,对研究区土壤的单元素环境质量进行分级并评价。以单元素土壤环境质量分级为基础,以单元素中最差的级别作为该单元土壤环境质量综合分级,评价研究区的土壤综合环境质量。通过单元素评价及综合评价认为,研究区内土壤环境质量总体状况优良,大部分地区为绿色、无公害的环境。

Abstract:

Soil pollution is an important factor which inhibits agricultural sustainable development. Soil environmental quality is related to geological conditions, natural conditions and human activities.This paper mainly used the surface soil geochemical data from multi purpose regional geochemical investigation and grading standards of As, Cd, Cr, Cu, Hg, Ni, Pb and Zn with reference to  the Soil Environment Quality Standard  (GB15618-1995), then classified and evaluated the single element environmental quality of soil in the Hetao area of Inner Mongolia. Based on classifying single element environmental quality and grading the worst level in the unit of soil environmental quality method we evaluated the soil comprehensive environmental quality in the study area.Using single element evaluation and comprehensive evaluation,it can be concluded that the total situation of the soil environmental quality is good in the study area, and that the environment is green and harmless in the mostly part of the study area.

Key words: Inner Mongolia, Hetao area, soil environmental quality, heavy metal, single element evaluation, comprehensive evaluation
