彭越浦苏州河河口底泥沉积特征与意义

在对彭越浦-东茭泾河道污染底泥分布的调查过程中，发现大部分河道底泥的垂直分布与苏州河及其支流大多数河道的底泥分布一致。而彭越浦交通路桥到中山北路桥段的河道底泥，却出现了特有的垂向分布。这种河道底泥从垂向上，其表层污染物含量较低，接近河道自然底泥的背景值。它是由于苏州河河水流入彭越浦，流速降低而形成的拥水沉积，其形成与彭越浦及苏州河的水文条件密切相关。这种特殊的河道底泥的发现，为苏州河支流及类似河道的治理提供了新思路。

Characteristics and Significance of Sediment in Pengyuepu Creek

Through investigation of the sediment of Pengyuepu Creek, it was found that the perpendicular distribution of sediment in the creek are as same as Suzhou Creek, the surface sediment was only slightly polluted, approaching to the natural sediment ground value, because it was closely eluted to the hydrodynanic condition of the creek and Suzhou Creek. This discovery will ofter a new method for dealing with pollution of the creek like Pengyuepu Creek.
