Abstract
The soil fertility of E.urophylla×E.grandis,Pinus massoniana Lamb and Acacia mangium plantations was compared by improved Nemerow composite index.The results were showed: the soil fertility index of three plantations was E.urophylla×E.grandisAcacia mangium Pinus massoniana Lamb in A soil layer,and was Acacia mangiumPinus massoniana LambE.urophylla×E.grandis in B soil layer,but the soil fertility of three plantations was not different after synthetic analysis.
