中文摘要：
对鸭绿江河口剖面沉积物中生源要素和重金属含量的垂向变化进行了分析，探讨了重金属元素之间和重金属与生源要素之间的相关性，总结了近百年来鸭绿江河口地区的环境演变过程。结果表明，除Cu以外，Cr、Ni、Zn、Cd、Pb、As和Hg之间及它们与生源要素之间有着很高的相关性，主要来源于工业和农业污染物排放等，Cu与其他环境因子有着不同的来源，人类括动对鸭绿江河口地区环境变化贡献极大；鸭绿江河口地区的环境演变过程可以分为3个阶段；总体上鸭绿江河口地区的污染状况日益严重。
英文摘要：
The environmental evolution of Yalu River estuary during last hundred years is investigated by analyzing the vertical variation of heavy metals, biogenie elements in the sediment and calculating the correlation coefficient between heavy metals and biogenic elements. Results showed that there is desirable correlation between heavy metals except Cu; these heavy metals also have better correlation with biogenie elements. This reveal that the heavy metals （except Cu） and biogenic elements share the same pollution source, they all discharged from industrial and agricultural pollution, while Cu came from different pollution source. Human activity has a grievous influence to the environment of Yalu River estuary; the environmental evolution of Yalu River estuary can be divided into three stages, in general, the pollution in Yalu River estuary become increasingly serious.
