Abstract Urbanization processes affect the accumulation of trace elements in urban soils. Due to rapid urbanization, are continuously emitted into soil and generate serious risk human health ecosystem. Therefore, effects urbanization on environmental quality along an gradient has emerged as important frontier research. We carried out this study assess distribution, pollution, potential ecological topsoil a typical Urumqi city, NW China. collected total 77 samples from urban, suburban, rural zones analyzed their concentrations nine elements: cadmium (Cd), cobalt (Co), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), antimony (Sb), vanadium (V), zinc (Zn). To estimate pollution elements, we employed load index ( PLI ) RI ). The results obtain indicated that concentrations, spatial distributions, levels, degrees investigated were closely correlated with process. distribution Cd, Co, Ni, Pb, Sb, V, Zn showed zonal pattern gradient. values decreased order > suburban rural, whereas suburban. Furthermore, considerable gradient, moderate zones, Hg poses most significant among elements. Overall, analysis is useful identify urbanization.
