With Yangtze delta tidal flat as an example, through the analysis on the magnetic characteristics of tidal flat sediment and the study on the space distribution of heavy metal elements, this thesis discussed the impact to Shanghai sea bank brought by heavy intensity development, and the interrelation between sediment power effect and heavy metal pollution space distribution. Utilizing the advantage of artificial intelligence neural network, in conjunction with environmental chemical analysis, from the angle of view of sediment magnetic characteristics, it analyzed the connection mechanism between magnetic mines and heavy metal element within tidal sediments, and built a quantitative magnetical diagnosis model, in attempt to calculating the tidal heavy metal pollution status from the magnetic measurement data of sediments and assess it's impact to the environment.

Phylogenetic analysis showed that the proteobacteria were the dominant group both in the sediments and waters,γ-proteobacteria and δ-proteobacteria were dominant in the sediments,α-proteobacteria were dominant in the water. However, all subphyla of proteobacteria presented phylogenetical divergence at the two sites.

各站位中主要为变形菌门，沉积物中γ-Proteobacteria和δ-Proteobacteria亚门占优势，水中则以α-Proteobacteria亚门占优势，但各亚门微生物在两个站位中存在明显系统发育学分歧。

The environmental transport of POPs in Dagu Drainage River selected as a typical example is reasonedly investigated in this article. Characteristics of sediment from DDR in Tianjin are analyzed. The mean value of TOC in sediments is as high as 8%, which is in favor of sorption POPs. The particle sizes of both suspended sediment and bottom sediment are mensurated by Malven Mastersizer. Silt accounts for about 60% in mass, while clay is about 10%. Particles of sediments belong to fine granule. Suspended sediment and bottom sediment mensurated by XRD mainly consist of quartz and illite, both account for 75.5% and 62.2%, respectively. The conformation of suspended sediment is very similar to bottom sediment from SEM photo.

采集自天津大沽排污河的底泥样品进行了特征分析：全河段底泥TOC含量较高，平均值约为8%，利于吸附POPs；Malven Mastersizer激光粒度仪测定了大沽排污河悬浮物和沉积物的粒径分布，结果表明主要以粉砂为主，占60%左右，其次为黏土，占30%左右，大沽排污河底泥颗粒属于细颗粒；悬浮物样品和表层沉积物样品经X射线衍射分析表明，石英和伊利石是大沽排污河底泥悬浮物及沉积物矿物的主要成分，两者之和分别占75.5%和62.2%；环境扫描电子显微镜结果表明，河流底泥悬浮物和沉积物的形态没有本质差别。
