|Summary:||This paper evaluates the elements of Hebei plain topsoil by referring to the three aspects of soil quality. Study shows that elements reflecting soil fertility quality are in a rich or fitting state, but the other ones including TOC, N, P, alkali-hydrolyzable N, Zn, Mo, effective Mo, effective B are insufficient, especially TOC, Mo, effective Mo are deeply lacking. According to Soil Environmental Quality Standard(GB-15618-95),it suggests that the environment of Hebei Plain heavy metal elements are favorable, and the exceeding-standard rate of these elements is very low. And the analysis of these heavy metal elements form shows that the bio-availability and potential harmfulness of Cd is much large and it is the most ecologically harmful element in the area. Among the elements which reflect the quality of soil health, F is rich or fitting while I is in relatively lacking state.|
