The cost of park-recreational, residential, and residential-transport urban landscapes of Moscow has been estimated taking into account land use and the relationships between ecosystem services and ecological functions and properties of individual landscape components. On the basis of the methodology previously proposed by the authors, a wide range of ecosystem services of urban landscapes, mainly associated with soils and their ecological state, has been assessed. The cost of ecosystem services provided by the soil in urban landscapes is 20–30 times higher in comparison with that of green spaces, and some soil services can be considered invaluable because of the difficulty of renewing this natural resource. The cost of ecosystem services of undisturbed soils of park and recreational landscapes is 1.5–2 times higher than that of anthropogenically transformed soils of residential and residential-transport urban territories. The main contribution to the overall cost of ecosystem services of soils in urban landscapes is due to the following services: carbon sequestration, preservation of the genetic material of biota, and filtration and accumulation of chemical elements in the ecosystem. These services can be considered as promising in the monetization of ecosystem services in urban landscapes. The decline in the cost of ecosystem services from park and recreational landscapes to residential and residential-transport landscapes is largely determined by the deterioration of the ecological state of soils. The benefits provided by the natural block of landscapes are comparable to or greater than those of the cultural (human-created) block. In relation to the all-Russia assessment of ecosystem services, a specific feature of urban areas is a significant share (on average, 25%) of the cultural block in the total cost of ecosystem services and a decrease in the cost of regulatory services by about 30%. The results of the economic assessment of ecosystem services of urban landscapes indicate an underestimation of the value of natural components, a significant contribution of soil to the natural block, the need to search for simplified integral indicators of its state, and the presence of cost calculation problems. The methodological approaches and provisional results of this study can be used in urban planning with the aim to preserve the soil cover of urban landscapes and optimize their functioning.
