The present paper aims to give a general survey of the status quo and trends of the urban soil contamination research in China in recent years. As is known, urban soil is one of the essential constituent parts of research that has had an important effect on the urban sustainable development. So the problems of urban soil contaminations have been paid more and more attention. During the last decade, the studies concerning the heavy metal pollution, organic pollution and biogenic pollution of surface soils in the urban areas, have been conducted around the world. However, large urban areas are seriously contaminated with concentrations of pollutants. These research results could systemically provide important scientific proofs of urban ecological environment quality. Since soil contaminations in urban environment are attached with more and more concern among the international scientific communities, the recent trends and emphases in research have been put on such issues as the conception and kinds of urban soil contaminations, the research about the combined pollution of urban soil, thirdly, remediation technologies, especially bioremediation technologies, the last but not the least environmental management policy.
