摘　　要：采集了珠三角某地区9条城市河流的表层底泥,利用BCR法进行底泥重金属形态的测定。同时统计了相关河流2010年间的水质状况,利用多元回归分析研究河流底泥重金属形态特征与河流水质的关系。结果显示,所选水质指标与底泥重金属的形态分布特征无显著相关,显示底泥的重金属形态不随河流水质的变化而改变。Surface sediments were collected from 9 urban rivers in the Pearl River Delta. The concentration of heavy metals was partitioning analyzed adopting the BCR sequential extraction procedure. The water quality of the corresponding rivers during year 2010 was also summarized. Multiple regression analysis of heavy metal fractionation in sediment and water quality was conducted, and the result showed that the selected parameters seem to have little influence on distribution of metal fractionation.
