The changes of soil nutrients and three community types(bushes,grass,and Robinia pseudoacacia)in the low mountain and hill district of Taihang Mountains are studied.By Shannon-Wiener index and the richness of the three community types,the communities are in a sequence of grass>shrub bushes>Robinia pseudoacacia and by the total coverage,the sequence is grass>shrub bushes>Robinia pseudoacacia.The contents of Zn,Mn,Na,Mg,and Fe in the three community types have no significant differences.Under the shrub bushes,the contents of Mn,Na,Mg,and Fe in subsoil are more than those in topsoil,but the differences are not significant except Zn.Under grass,the contents of Mn,Zn,and Na in subsoil are more than those in topsoil.Zn,Mn,Na,Mg,Fe,and organic matter are not significantly correlated.Mn and other nutrient elements,Fe and other nutrient elements(Na is significant correlated),as well as Mg and Na are all in extremely significant correlation.
