Abstract

Existing plans for the development of the continental coast and the islands of the Peter the Great Bay suggest establish-ing of large economic clusters. The most important condition for achieving sustainable development of the emerging natu-ral-economic system is to implement spatial planning of coastal zones. The work is based on the information about the nat-ural complexes of the territory and water area, obtained through landscape approach. The territory of the Shkota Island and its submarine slopes were used as a key area for the study of the features of the spatial organization of landscapes of coastal geostructures. We used a complex of physiographic, geoecological, cartographic and statistical research methods. For ter-restrial landscapes, 49 observation points are described and 4 profiles are laid; for underwater landscapes 64 observation points are described and 18 profiles are laid. As a result, a unified structural-genetic classification of land and underwater landscapes is established, the landscapes are mapped, and zones of interaction between aerial and aquatic natural complex-es are identified. The results obtained are the basis for identifying priority types of coastal-marine environmental manage-ment, functional zoning and spatial planning.

Abstract

The implementation of the sustainable development objectives, requires additional knowledge about underwater landscapes of inland reservoirs. In this article, we assumed that (1) underwater landscapes of lakes are shaped mainly by the type of substrate and the assemblages of flora and fauna inhabiting a given reservoir; (2) vegetation is one of the most important elements of underwater landscapes, which dynamically reacts to environmental changes. This article presents the results of a study on the underwater landscapes of Lake Wielki Staw in the Karkonosze Mountains. Thirteen types of underwater landscapes were distinguished in the lake based on underwater inventory and spatial analysis using ArcGIS 10.7 software. The level of changes that occurred in the underwater landscape studied was determined using the underwater landscape structure maps for 2005, 2011, 2017, and 2021. In addition, the landscape change index ( LCI) for Lake Wielki Staw was determined for 2005–2011, 2011–2017, and 2017–2021. The results obtained indicate that underwater landscapes in lakes, similarly to terrestrial landscapes, are dynamic and subject to changes. In the case of Lake Wielki Staw, the changes in the range of Isoëtes lacustris communities in individual parts of the lake limited the differences in the area of all types of underwater landscapes distinguished. This allows us to use underwater vegetation inhabiting a given reservoir as an indicator of changes in underwater landscapes. Keywords:
