With the rapid development of urbanization and industrialization in China, whether the abandoned industrial land can be reused has become the focus of land planning. So soil environmental quality assessment on the abandoned land is necessary. In this paper, the land of a discarded chemical plant in Chongqing, China was chosen as the study object. The concentrations of heavy metal were studied. Single Factor Pollution Index (SFPI) and Integral Pollution Index (IPI) were applied to assess the degree of soil pollution. The results revealed that the abandoned industrial soil in this work was slight polluted and could only be planned for the 2nd type of land utilization, including green land, commercial land, public facilities land, etc.
