Abstract Huang-huai-hai and Bohai Rim protected vegetable region is one of the 6 advantage regions for
vegetable development in China．By collecting document database from 2011-2019 on studying heavy metals
in protected vegetable fields at Huang-huai-hai and Bohai Rim region，this paper carried out statistic analysis on
heavy metals pollution and environment quality of this region．The results showed that the soil heavy mental
contents of Cu，Zn，Cr，Ni，Pb，Cd，As and Hg in protected vegetable fields at Huang-huai-hai and Bohai
Rim region were all lower than the standard limit value issued by environmental quality evaluation made in
greenhouse vegetables production region（HJ/T333—2006）．Compared with soil background value of each
province，there existed remarkable heavy metal Cu，Zn，Cd and Hg accumulation．Cr and As did not appear
any accumulation in this region．The scope of single pollution index of 8 heavy metals was between 0.30 and
0.80．The order was Cd ＞ Pb ＞ Hg=Ni ＞ Zn ＞ Cu ＞ As ＞ Cr．Only Cd was on the warning grade．The
rest heavy metals were all at the clean grade．The average comprehensive pollution index was 0.75，indicating
that heavy metal pollution for this region was at the alert level．Measures for preventing and controlling heavy
mental pollution should be adopted．
