In order to understand the relationship between soil physical and chemical properties as well as biological charateristics of the various indicators in vegetation restoration area of Kunyang phosphoritemine, apatite plantations with eight different vegetation restoration years in Kunyang were selected to examine the soil thickness, bulk density, porosity and capillary porosity, water content, pH value, organic matter, alkali-hydro nitrogen, total nitrogen, total phosphorus, available phosphorus, available potassium, total potassium and soil microbial biomass carbon (MBC), microbial biomass nitrogen (MBN), nitrogen mineralization rate, beta glycosidase enzymes, acid phosphatase, urease, 4 typical variables were obtained through canonical correlation analysis for the relationship between 13 soil physicochemical property indexes and 6 soil biological character indexes, and the canonical correlation coefficients were 0.997 0, 0.988 9, 0.879 9 and 0.997 0, respectively, which have reached very significant level (p≤0.01).There were significant correlation between soil physical and chemical properties and biological properties. Organic matter and MBC, MBN were very significantly correlated, urease, effective phosphorus, total phosphorus and nitrogen mineralization rate and MBN, MBC were significantly correlated, alkali solution nitrogen, pH, MBC, MBN, urease were significantly related to total nitrogen and beta glycosidase enzymes, MBN, nitrogen mineralization rate were significantly related.
