Аннотация:Purpose of Review In this review we, frst, describe the geosystem approach to studying landscape structure and functioning developing in the twenty-frst century in Russia. Second, we highlight the dominant research targets. Third, we classify research issues into leitmotifs that allow getting insight into systemic organization of a landscape. Finally, trends and prospects for each leitmotif are discussed.Recent Findings We identifed six principal research targets: (a) delineation, description, and classifcation of geosystems; (b) identifcation and quantifcation of radial relationships between geocomponents and lateral relationships between geosystems; (c) assessment of natural complexes for applied purposes; (d) forecast of changes under the infuence of internal or external forces; (e) adaptation of human activities to spatial diferences within a landscape; (d) planning activities in connection with existing spatial diferences. Seven leitmotifs are commonly followed: (a) geotopological quasi-determinism;(b) landscape diversity; (c) inter-geocomponent radial relationships; (d) integrating and diferentiating function of lateral fows; (e) self-development, self-regulation, and self-organization; (f) emergent efects of spatial interactions; (g) chronosequence of dynamic states and evolutionary stages; (h) landscape as a reactor. The present-day concept implies the focus on multiplicity of landscape-forming processes acting at various scale levels, self-development, and probabilistic relationships between geocomponents and between geosystems.Summary Current trends in geosystem studies are expected to increase understanding emergent efects of spatial relationships, to ensure 3-dimensional multiscale and polystructural view on landscape, to focus on nonlinearity and criticalthresholds in between-geocomponent relationships, and to elaborate quantitative predictive models of future spatial patterns.
