Systematic sampling of soils was conducted in the planning area of Langfang city. N, P, K, Ca, Mg, Fe, Cu, Zn, Mn, B, Mo, Co, Hg, As, Pb, Cl, Cd, F, Se, Cr, I and pH values were analyzed. Soil background values of the area were compared with those of the whole China and the world. Environmental assessment of plough layer soil indicates that the soil quality is better in the northwest part and worse in the southeast part, with Xiwu, Daguanzhang, Zhougezhuang-Pengzhuang and Dazaolin along the Jingshan Railroad being worst. The pollution source is closely related to industry and agriculture, waste gas, waste water and waste solid.
