The article discusses the results of the complex landscape survey of the Nabil plain, Northern Sakhalin, Russia. The 20 km long landscape profile allocates three major geographical complexes. The main pattern of the landscape structure is related to the age and genesis of the area. The current landscape structure of the Nabil plain includes 31 land units. Within the landscapes, the peculiar features of the soil and vegetation cover are observed, and the main factors of landscape differentiation are the redistribution of runoff associated with the topography and lithological conditions. The spatiotemporal sequence of the land units at the recent marine terraces is related to the coastal sediment accumulation and redeposition. Seven land units are identified here. As a result of mechanical disturbance and deflationary processes in the initial weakly stable complexes of coastal terraces, disturbed land units occupy up to 30 % of the total landscape area. For the coastal plain, 10 land units are identified; up to 90 % of the total landscape area is covered by swamps. Pyrogenic modifications occupy up to 70 % of the total landscape area. The highest landscape diversity is characteristic of the piedmont plain (14 units of the first order). The high conservation value of the dark coniferous forests dominating the landscape is shown. Modified and weakly stable land units (cleared areas and disturbed swamps) occupy up to 1 % of the landscape area. The landscape structure and diversity are represented on a large-scale map; its fragments reflect the main patterns of the landscape distribution and contain information on topography, soils and vegetation. The large-scale map can be used for the environmental monitoring goals, taking into account increasing levels of the man-caused impact at the natural complexes of the northern Sakhalin.
