Особое внимание уделено  обоснованию  уникальности  полигона как  первой в  России  и мире  площадки  подобного  типа,  формируемой  на  крупном внутриматериковом замкнутом водоёме. Использован комплексный анализ литературных данных, материалов дистанционного  зондирования  (Sentinel‐2,  Landsat‐8),  цифровых моделей  рельефа  и  полевых  наблюдений.  Применены  методы геоморфологической  типизации  берегов,  анализа  динамики береговой линии и оценки ландшафтно‐экологических рисков. Установлено,  что  современная  регрессия  уровня  Каспийского  моря вызывает  интенсификацию  аккумулятивных  процессов:  рост  кос  и баров,  обмеление  лагун,  расширение  солончаковых  и  песчаных массивов. Выявлена высокая чувствительность дельтовых комплексов Терека, Сулака и Самура к изменениям уровня моря и речного стока. Оценены  основные  ландшафтно‐экологические  риски: опустынивание,  вторичное  засоление,  деградация  водно‐болотных угодий. Обоснована необходимость создания карбонового полигона «Каспий» как  ключевой  и  в  то  же  время  уникальной  площадки  для долгосрочного  мониторинга  углеродного  баланса  и  состояния прибрежных  экосистем  на  крупном  внутриматериковом  замкнутом водоёме. Показано, что  такой  полигон не имеет аналогов в России и мире,  что  подчёркивает  его  значимость  для  изучения трансформирующихся  природных  систем  и  апробации  ГИС‐методов прогнозирования изменений береговой зоны в условиях динамичных природных и антропогенных процессов</p></abstract><trans-abstract xml:lang="en"><p>The  study  investigates  the  geomorphological  structure,  morphodynamics and  landscape‐ecological  characteristics  of  the  Dagestan  coast  of  the Caspian  Sea  in  order  to  provide  a  scientific  rationale  for establishing  the aqua‐territorial  carbon  polygon  “Caspiy”.  Special  attention  is  given  to substantiating the uniqueness of this polygon as the first facility of its kind in Russia and worldwide to be created on a large inland closed water body. The  study  is  based  on  a  comprehensive  analysis  of  published  sources, remote  sensing data  (Sentinel‐2,  Landsat‐8),  digital elevation models and field observations. Methods applied include geomorphological typology of coasts,  shoreline  dynamics  analysis  and  assessment  of  landscape‐ ecological risks. It  has  been  established  that  the  ongoing  regression  of  Caspian  Sea  level intensifies accumulative processes, including the growth of spits and bars, lagoon  shallowing  and  expansion  of  saline  and  sandy  landforms.  High sensitivity of the Terek, Sulak, and Samur delta complexes to sea‐level and river  discharge  variations  has  been  identified.  Key  landscape‐ecological risks have been assessed, including desertification,  secondary salinisation and degradation of wetlands. The study substantiates the need to establish the “Caspiy” carbon polygon as a key and at the same time unique platform for long‐term monitoring of the  carbon  balance  and  coastal  ecosystem  dynamics  on  a  large  inland closed water body. It is shown that no analogous polygon exists in Russia or  globally,  which  underscores  its  significance  for  studying  the transformation of natural  systems and  for  testing GIS‐based methods  for predicting coastal zone changes under dynamic natural and anthropogenic conditions. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Каспийское море</kwd><kwd>дагестанское побережье</kwd><kwd>береговая геоморфология</kwd><kwd>морфодинамика</kwd><kwd>регрессия  уровня  моря</kwd><kwd>аккумулятивные  берега</kwd><kwd>дельты  Терека</kwd><kwd>Сулака  и  Самура</kwd><kwd>лагунно‐барные  системы</kwd><kwd>ландшафтно‐экологические  риски</kwd><kwd>дистанционное  зондирование</kwd><kwd>ГИС‐картографирование</kwd><kwd>карбоновый полигон «Каспий»</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Caspian  Sea</kwd><kwd>Dagestan  coast</kwd><kwd>coastal  geomorphology</kwd><kwd>morphodynamics</kwd><kwd>sea‐level  regression</kwd><kwd>accumulative  coasts</kwd><kwd>river  deltas  (Terek</kwd><kwd>Sulak</kwd><kwd>Samur)</kwd><kwd>lagoon  and  bar  systems</kwd><kwd>landscape‐ecological  risks</kwd><kwd>remote  sensing</kwd><kwd>GIS mapping</kwd><kwd>“Caspiy” carbon polygon</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 25‐17‐20040 «Пространственновременная изменчивость приморских природных и антропогенных ландшафтов Дагестана под влиянием современных климатических изменений и колебаний уровенного режима Каспийского моря»  (http//rscf.ru/project/25‐17‐20040/).</funding-statement><funding-statement xml:lang="en">This work was supported by the Russian Science Foundation, grant no. 25‐17‐20040, «Spatiotemporal variability of coastal natural and anthropogenic landscapes of Dagestan under the influence of modern climate change and fluctuations in the level regime of the Caspian Sea» (https://rscf.ru/project/2517‐20040/).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Рычагов Г.И.
