Modeling of the structure and functioning processes allows to create schemes of landscape planning for long-term sustainable forest management and zoning geosystems in order to localize quickly hydrological processes. The investigation site was in southern taiga within the marginal zone of Würm glaciation in European Russia. The structure of natural complexes was described by quantitative classification based on morphometric parameters, digital terrain model and space image. Classification of relief was performed using parameters that describe gradients of geophysical fields of gravity and solar radiation. Landsat 7 data were used to decipher plant cover patterns. Classes were verified by field data from forest inventory using discriminant analysis. Modeling long-term dynamics of the uneven stands conducted using the two most contrasting scenarios - the natural development of forests and continuous felling. The simulation results as a basis for zoning on the recommended methods of forest management. Landscapes hydrological functioning was researched on the small watershed with boggy forest and represents limnoglacial landscape. Calculation of flow was made in GIS SAGA (Böhner, et. al., 2004) exclusively under the apri-oristic data. Modeling of the landscapes structure has allowed to set the distributed parameters of watersheds, such as factor of a roughness “Manning’s n”, factor of “Curve number”, et al. The calculate data of flow rate has shown, that the tabular values allow to reveal essential distinctions in distribution of runoff rates in various geosystems. Field measurements of runoff have been spent for verification of calculations data. Modeling of surface runoff based on the geosystems structure enabled a watershed zoning on time lag until discharge lines.
