| 摘 要： | 通过对九龙江河口表层沉积物的重金属元素含量、沉积物粒度等要素进行分析,结合相关与聚类分析等统计手段,探讨了九龙江河口地区的沉积环境与重金属元素含量特征的关系.结果表明,即使在沉积环境复杂的河口地区,重金属含量分布与沉积物粒度仍存在明显的对应关系.受沉积动力影响,不同的重金属元素分布在九龙江河口地区表现出较大差异,而嵩屿至屿仔尾一带呈带状南北向展布的重金属相对高值条带值得引起注意.

| Abstract: | The surface sediment grain size and contents of heavy metal in the Jiulongjiang Estuary is analyzed.With correlation and cluster analysis the relationship between the heavy metal distribution and the sedimentary environment is discussed.The result shows that even in the estuary where the sedimentary environment is complex,there is a significant correlation between the distribution of heavy metals and surface sediment grain size.On the effect of sedimentary dynamics,the heavy metal distributions are quite different in Jiulongjiang estuary.The relative high value belt of heavy metal in SN direction between the Songyu and Yuziwei should be emphasized. |
