Urban soils are a complex transformed system. The most widespread over the the city area is technogenic lithogenesis, which determines the formation of new deposits with different properties. The researchers use the substantial genetic classification of trasformed soils and soil formations in industrial zones of the city of Khabarovsk. The basis for the selection of the horizon sequence is the classical ABC system. In the morphological description of the sections, attention is drawn to the newly formed soil bodies formed on modern deposits of different genesis, as well as to their position in elementary landscapes. Indicators of respiratory activity and phytotoxicity of soils permit to consider changes in their biological activity under the anthropogenic pressure. The research results presented have shown that there is no firm attribution of respiratory activity to soil formations in industrial zones; in each industrial zone, it is due to the functional type of sediments. The spatial variation of biological activity is significant and, in general, lies within its low values. The results obtained indicate the need to select specific remediation measures for each industrial zone, according to the soil formation state.
