摘要
应用地质累积指数法对流经连云港市内的四条河流（蔷薇河、排淡河、盐河、烧香河）表层沉积物重金属污染进行分析评价，结果表明，河流表层沉积物重金属中Pb、Hg、Cd、As按地质累积指数分级均为0，属于无污染范畴，Cr、Zn、Cu地质累积指数分级在0～2之间，属于无污染到中度污染范畴，河流主要污染物是Cr。
The heavy pollution of surface layer deposit in four rivers of Lima Ytm Port city with geological accumulated index was evaluated. The result showed that geological accumulated index of Pb,Hg,Cd and As in heavy pollution of surface layer deposit were zero, they belonged to no pollution scope; and geological accumulated index of Cr,Zn and Cu were from zero to 2, they belong to scopes from no pollution to medium pollution, the main pollutant of river was Cr.
