摘要/Abstract

摘要：

重金属元素及其他元素在土壤圈中长期积累到一定程度后会对环境造成影响并对食物链产生危害，对土壤进行元素的污染程度划分有助于及时掌握土壤环境现状。运用多目标区域地球化学调查数据，将Hg、Cd、As、Pb、Cu、Zn、Ni、Cr等8项重金属元素按照土壤环境质量一级标准值、F元素一级推荐值，分别采用尼梅罗公式计算其污染指数，绘制污染程度图。将银川盆地划分为清洁区、基本清洁区、初始污染区、轻度污染区、中度污染区和重度污染区，并分析总结了污染来源。

关键词: 多目标地球化学, 银川盆地, 土壤环境, 污染程度

Abstract:

Being chronically accumulated in the pedosphere, the heavy metal elements and other elements bring certain influences on the environment and consequently were harmful to the food chain. The division on pollution degree of soil elements is of great importance to acquire current soil environment situation. Based on the multiobjective regional geochemical survey data, in this paper, heavy metal elements including Hg, Cd, As, Pb, Cu, Zn, Ni, Cr according to soil environmental quality level Ⅰ standard value and F element according to level Ⅰ recommended value were chosen to calculated the pollution index by Nemerow formula and finally used to drew the figure of soil pollution levels, respectively. As a result, the Yinchuan basin would be divided into cleaning area, basic cleaning area, initial pollution area, light pollution area, moderate pollution area and severe pollution area, and additionally the pollution sources were also analyzed and summarized.

Key words: multi-objective geochemistry, Yinchuan basin, soil environment, pollution degree
