We studied the heavy metal pollutio of surface water, Xuzhou. The pollutio i te sity of the bottom sedime ts has bee assessed based o the si gle_factor co tami a t i dex. The results showed that except Yu lo g Lake, the bottom sedime ts of surface water i Xuzhou was co tami ated severely by heavy metals i differe t degree. Ji ma River was co tami ated most serious, a d the it was Kui River a d Aba do ed Yellow River a d the Ji gha g Ca al. The fifth Mo itori g dot i Yu lo g Lake was also co tami ated by Hg. The co tami atio degree a d eleme t was relatedwith i dustry structure i Xuzhou.
