摘要:基于洪泽湖近 20 年(1975-2004)来的相关研究,对洪泽湖输沙量和底泥的分布特征及理化性质
各指标的含量等数据进行了搜集处理和分析。统计和分析了相关理化性质的空间特征分布与变化趋
势,洪泽湖入湖输沙量大于出湖输沙量,呈淤积状态;对洪泽湖底泥中的总氮、总磷、重金属等进行了评
价,重金属大部分元素达到土壤评价二级标准,重金属污染属于重污染,与镉浓度含量超标有关。提出
了防治洪泽湖底泥污染的措施。

Abstract:
physicochemical properties of Lake Hongze sediments and sediments runoff were collected and analyzed.
Sediment runoff into the lake exceeds that out of the lake which made it in silting situation. The distribution
and variation tendency of certain physicochemical properties were analyzed and evaluated. TN, TP and heavy
metal concentrations in the sediments were evaluated. Most heavy metals achieved secondary standard
