A preliminary study was carried out on vertical distributions of selected soil properties and trace metals in typical calcareous fluvo-aquic soil profiles under different land use. Results indicate that in vegetable fields and upland soils, the topsoil (0~15 cm) is higher in organic carbon content, lower in pH and CaCO₃ content than the other layers in the soil profiles, and shows significant Cd accumulation, however, the concentrations of Cd, Pb, Cu and Zn have not yet exceeded the second grade criteria of the National Standard for Soil Environment Quality of China. Totals of some trace elements in the top soils do not vary much between vegetable and upland soils, but the concentration of DTPA-extractable Cd in the topsoil is significantly higher in the former than in the latter. In light of distribution of the trace elements in the profiles, surface accumulation is quite obvious of total Cd and DTPA-extractable Cd, Pb, Cu, and Zn in calcareous fluvo-aquic soil. This phenomenon is significantly related to content of soil organic matter, soil pH and content of soil CaCO₃. Result of cluster analysis shows that it is more advisable to collect mixed multisite soil samples from the surface soil layer (0~15 cm) for soil environment analysis.
