| 摘 要： | 磁学参数作为环境污染的一项重要指标,在现代环境污染研究中发挥着重要作用.通过对许昌市清潩河表层沉积物磁化率进行测定,结果显示:在清潩河北段磁化率均值为36.8×10-8m3·kg~(-1),中段均值为29.8×10-8m3·kg~(-1),南段均值为44×10-8m3·kg~(-1).南段磁化率最高,北段次之,中段最低.受到污染严重的区域磁化率值较高,污染轻的区域磁化率值较低,磁化率对环境污染具有指示性.城市河流表层沉积物磁化率的测定,可以为城市河流污染监测、城市污染空间判断提供一种便捷手段.

| Abstract: | Magnetic parameters as an important indicator of environmental pollution play an important role in modern research on environmental pollution. Magnetic susceptibility of Qing-Yi River surface sediments in Xuchang is measured,and the results show that: the mean value of magnetic susceptibility in the upstream,midstream and downstream is 36. 8 × 10- 8m3·kg~(-1),29. 8 × 10- 8m3·kg~(-1),and 44 × 10- 8m3·kg~(-1)respectively. The research reveals that seriously contaminated areas have high magnetic susceptibility values,and less contaminated areas have lower magnetic susceptibility values. The results show that the magnetic susceptibility is indicative of environmental pollution,and can be used as the indicator of the pollution levels. |
