An approach is proposed for the assessment of ecosystem services of various components of the landscape of urban forest parks. The methodology takes into account the environmental and recreational functions of the territory, is based on the interconnection of ecosystem services, ecological functions and the properties of individual components of the landscape. The assessment is carried out in a differentiated way, taking into account the decrease in the quality of the services provided in conditions of significant anthropogenic load. It is shown that the greatest contribution to the cost of services is made by the soil.
Keywords: ecosystem services of urban forest parks; ecological condition of soils; degradation of soils and vegetation; economic evaluation of ecosystem services

Ecological state of soils and tree vegetation in urban park-recreational landscapes (the case of the Catherine park of Moscow)Moscow University Bulletin. Series 17. Soil science. 2019. N 4. p.11-19read more997

The influence of anthropogenic activity on the quality of urban alluvial soils, the conditions of growth and the state of tree plantations is estimated. The level of negative consequences for natural components correlates with the degree of human exposure. In the profile of soils moisture decreases, humus content varies in different directions, pH of waters and electrical conductivity increase. Densification of soils and inhibition of biological activity are noted in the surface horizons. The coefficient of the ecological state of soils decreases by 6-24% compared to the optimum conditions. The correlation analysis showed the presence of a significant weak matching between vegetation state and soil quality (Spearman's coefficient is -0,53).

The article discusses the existing methodological approaches used in Russian and foreign studies of urban soils. The analysis of methods for studying the soil cover as an object of landscape design, considering its formation and functioning on the example of the Moscow city. Information is provided on the territorial and functional organization of urban space. From the point of view of methodological approaches for the study of urban soils, it is proposed to divide them into two groups: uneven-aged soils with bulk surface horizons from various recultivants, formed according to design documents, and natural and surface-transformed soils without filling layer. The features of methodological approaches for studying each soil group are considered. It is noted that the material composition of the ground materials from which urban soils are formed has a significant impact on their structure, properties and functioning. The use of ground materials of different composition and properties for the formation of the upper part of urban soils, sometimes an unknown history of their functioning and land use, and possible numerous violations cause extremely high and most often unsystematic spatial and temporal variability of urban soils. With the increasing interest of the scientific community in the qualitative assessment of the urban environment, the most promising is the development of methods for studying the resulting ecological functions of urban soils using integral indicators, as well as the development of approaches, methods and technologies for creating urban soils that meet the criteria of green environmental management.

A detailed morphological study of bog-podzolic superficial-gleyed soils (sod-humus and peaty subtypes) and living ground cover within the soil-geochemical catena in Moscow region Solnechnogorsk district was conducted. For the first time, more than 20 morphological indicators of soils within the organogenic, eluvial and eluvial-illuvial parts of the profile were determined and analyzed over a thirty-year period. At the same time, the characteristics of the associated living ground cover (biomass, proportion of hygrophytes, moisture and trophicity scores according to L.G. Ramensky) were studied. Based on monitored indicators analysis, it was shown that convincing and reliable identification of the degree of bogging of a biogeocenosis is possible without additional analytical studies of soils and plants. Mathematical analysis of field research results indicates statistically significant relationships between the degree of swamping and such indicators as the proportion of hygrophytes, moisture score, litter thickness, the ratio of subhorizon reserves F/L, the thickness of the eluvial horizon, the depth of gleying from the lower boundary of the organogenic layer, and the abundance and size of nodules. It is likely that in the landscape, the soil serves as an “archive” of hydromorphism conditions of varying degrees, while the living ground cover can serve as a sign of swamping only at significantly pronounced process stages. The greatest contribution to the hydromorphism of the studied bog-podzolic surface-gleyed soils is made by: the groundwater level, the upper boundary of the appearance of signs of gleying from the lower boundary of the organogenic horizon, the general abundance of spots in the eluvial horizon, the average size of nodules in the eluvial-illuvial horizon.
