Аннотация. Детальное картографирование ландшафтно-морфологической структуры Анапской пересыпи выполняется в рамках мониторинга ее состояния в связи с необходимостью охраны и защиты этого ценного рекреационно-бальнеологического ресурса в условиях сильного антропогенного воздействия. Представлены результаты составления ландшафтно-морфологической карты на восточную часть Бугазского участка пересыпи по материалам детальной цифровой аэросъемки. Выявленные особенности дюнного рельефа и его природной и антропогенной динамики необходимо учитывать при разработке мероприятий по защите и охране пересыпи.

Summary. The Anapa Bay Bar is the accumulative coastal land formed with dune belt at the North-Eastern part of the Black Sea coast. It represents a valuable recreational-healthy resource. Status of Anapa as the Federal level health resort, received in 1995, has increased the number of recreants recently. Uncontrollable anthropogenic influence leads to destruction of dune belt. Detailed mapping of landscape-morphologic structure of bay bar is necessary for creation of adaptive solutions for bay bar conservation and defense. Such mapping is carried out by separate parts. The results of mapping for the Eastern part of Bugaz bay bar (which is one of Anapa bay bar regions) using digital air photos in scale 1:2000 are represented in this article. The part of the bay bar between canals of fishery farm and restoration base Kassandra is used by kite surfing and wind surfing sportsmen which place tents and trailers during the training season. Due to dense network of unregulated ways and roads to the beach, front dune ridge, which commonly follows shore behind the beach, has been destroyed and separated into fragments here. Narrow gullies, which are situated perpendicular to dune belt, became the corridors of blow out and moving waves at place of roads and ways to beach. Sand blows out from beach along them, forming the Aeolian cones, and sea water runs along them into lagoon during sea storms. As the result of this process hydrogen cones are formed, lowlands around lagoon and their swamping undergo abrasion. These destructive processes, caused by anthropogenic activity are coupled with natural ones (wave abrasion of dune ridges at part of bay bar with narrow beach in this region). The 300 m part of dune ridge to the East of fishery farm has been completely eroded by waves. Investigated peculiarities of landscape-morphologic structure and its changes with anthropogenic impact must be taken into account when establishing the regime of bay bar usage and for creation of protecting and defending measurements for dune belt.
