Abstract:An evaluation method of soil integrated fertility was developed and used for evaluating soil fertility in the hilly and mountainous region of Southeastern China,with soil fertility being considered as a com plex of the state the capacity to regulate and transform the materials needed by of soil nutrients and plants.With systematic principle and the data of the Second National Soil General Survey,11 indexes were divided into two groups representing,separately,states of sail nutrients and environments of nutrient supplying,involving content of soil orgasie matter,total N,total P2O5,total K2O,available P2O5 available K2O,pH, CEC,physical clay,silt-clay ratio and thickness of epipedon.Then two types of membership functions of these indexes,S-type and parabola-type,were developed based on their effects on plants.Their values of function were also calculated. Through factor analysis of these vslucs with software STATGRAPHICS,weight values of these indexes were decided.Finally,IFI (Integrated Fertility Index) of different soils was calculated according to addition-multiplication principle.
Keywords:Soil fertility  Comprehensive evaluation  Hilly and mountainous region  Southeastern Chiga  GIS
