【Abstract】 Rapid urbanization has huge impact on soil resources, bringing serious challenges to food security, ecological health and environmental safety. As a kind of irrenewable natural resources, soil has at least fix functions, which could spatio-temporally evolve, exchange and disappear during the transformation of natural ecosystems into the urban systems dominated and heavily managed by human beings. Impact of urbanization on soil resources and environment could be reflected by the conflict between urban and agricultural land use, the risk of potential pollution from urban sources, and the shift of agricultural structure and soil utilization. During urbanization, proper management with minimal impact on the environment, in which all these main uses of soil and land are a spatial and/or temporal harmonization, will play a key role in sustainable regional development.更多还原
