The distribution of phosphate (PO 4 3- ) and the relationships between PO 4 3- and several constituents in groundwater were studied. Partial correlation analysis relating PO 4 3- to types of land use was conducted using the data analyzing tool SPSS 15.0. The processes controlling the transport of PO 4 3- are discussed. The conclusions from this study are: (1) urban land use has obvious impact on PO 4 3- in groundwater, the average concentration of PO 4 3- being 4.37mg/L, greater than that resulting from farmland and mixed land use, which have average PO 4 3- concentrations of 0.10 and 0.18mg/L, respectively; (2) the partial correlation between PO 4 3- and types of land use is significant with a coefficient of 0.760; (3) the PO 4 3- concentrations in surface water are generally higher than those in groundwater, and the total phosphorus (TP) concentrations in river sediments are generally higher than those in soil samples; (4) groundwater is a carrier of PO 4 3- and is likely responsible for the redistribution of PO 4 3- in different regions of NRB.
