Abstract

Heavy metal pollution in soil is becoming a widely concerning environmental problem in China. The aim of this study is to integrate multiple sources of data, namely total Cu and Pb contents, digital elevation model (DEM) data, remote sensing image and interpreted land-use data, for mapping the spatial distribution of total Cu and Pb contamination in top soil along the Le'an River and its branches. Combined with geographical analyses and watershed delineation, the source and transportation route of pollutants are identified. Regions at high risk of Cu or Pb pollution are suggested. Results reveal that topography is the major factor that controls the spatial distribution of Cu and Pb. Watershed delineation shows evidence that the streamflow resulting from rainfall is the major carrier of metal pollutants.

摘要

土壤重金属污染在中国正成为一个广受关注的环境问题。本研究的目的是整合多种数据源，即土壤中总铜和总铅含量、数字高程模型（DEM）数据、遥感图像和土地利用解译数据，来绘制乐安河及其支流表层土壤中总铜和总铅污染的空间分布。通过地理分析和流域划分，确定了污染物的来源和传输途径。并提出了高风险的铜或铅污染区域。结果表明，地形是控制铜和铅空间分布的主要因素。流域划分表明，降雨产生的地表径流是金属污染物的主要载体。
