以珠江近岸河口海域为研究对象，利用该区域2003-2005年沉积物中重金属元素（Co、Cu、Ni、Pb、Cr、Zn、Zr）含量实测资料和相关统计数据，通过对该区沉积环境分析的基础上建立简化计算模型，对该区域沉积物中重金属元素的输入、输出以及沉降富集含量进行了定量计算。结果表明，年均输入、输出以及沉降在研究区的重金属含量惊人，其中Cr和Zn富集最大，均超过2000 t/a，其次为Cu、Ni、Pb，均超过1000 t/a，Co富集相对较少。定量计算分析结果对于进行该区域的环境治理具有一定的指导作用，并且更加明确了河口近岸海域作为陆地和海洋的过度区域具有重要的生态和环境意义。

Based on the content data of heavy metal(Co、Cu、Ni、Pb、Cr、Zn、Zr) in 78 surficial sediments in the estuary region of Pearl River during 2003~2005 and the environmental analysis of the study area, a simplified calculation model of heavy metals was founded. The results show that the average annual input, output and deposition of heavy metals in the study area is alarming, in which the maximum enrichment of Cr and Zn, are more than 2000t/yr, followed by Cu, Ni, Pb, are more than 1000t/yr, the enrichment of Co is relatively small. The results has a guiding role for the quantitative calculation of environmental governance in the region, and it is benefit for make clear ecological and environmental importance of the estuarine area.
