应用属性识别模型评价运河杭州段底泥污染

利用属性识别模型，对运河杭州段底泥进行分层(浮泥层、淤泥层、基底层)，评价其中的总磷及其他7种重金属的污染程度，经研究发现：表层污染程度高于底层；污染程度最严重的是Cd和Zn，OP、Cu、Pb对污染的贡献度大大小于Zn和Cd，而As、Hg、Cr几乎没有对底泥污染作出贡献。总体而言，运河杭州段底泥污染程度属于中等污染，希望本研究能够为运河杭州段的底泥污染治理提供一定的借鉴作用。

Evaluating Bottom Sludge Pollution of the Hangzhou Segment of the Canal by Using Attribute Identity Model

This article evaluates the pollution degree of organic phosphor and seven other heavy metals of bottom sludge of the Hangzhou segment of the Canal by dividing layers (surface layer,sullage layer, and bottom layer) and using attribute identity model.From the reaserch we found: the surface pollution degree is higher than that of the bottom;the most serious factors are Cd and Zn, whose contribution is much higher that of Op, Cu and Pb. Furthermore,As,Hg and Cr have very little contribution to the whole pollution of bottom sludge. It can be considered that the pollution of Hangzhou segment of the Canals is of moderate degree and it is hoped that our study could provide the reference for the harnessing of the bottom sludge pollution at Hangzhou segment the Canal.
