Abstract:

     From the view of agriculture land, the paper selects the indexes of soil fertility and environment health, statistically analyzes geochemical distribution of elements contained in the Wuchang area by geochemical method. Referring to Background Value of Soil Environmental Element in China published in 1990 and on the base of standards of environmental quality of soil in China, the paper draws the conclusion as following: in the Wuchang area, the element contents of N, K, C, Mg and S, contained in organic matter and essential elements in plants are relatively abundant by comparison with the background value of the layer A soil all over Chinese whole country;the contents of P and Ca are relatively low. We comprehensively evaluate the contents of heavy metals such as Hg, Pb, Zn, Cu, As, Cr,and Ni.The results show that 99 percent of the soils in the Wuchang area accord with standard of grade I. Among the essential trace elements, Fe, Mn are abundant by comparison with the background value of the layer A soil of the whole country;the contents of B, Mo, Zn and Cl are relatively low.
