В работе произведена оценка информационной ценности экогеографических предикторов, полученных на основе данных дистанционного зондирования Земли со спутников, для отображения особенностей экологической ниши лебедя-шипуна Cygnus olor (Gmelin, 1803) в период зимовки в пределах залива Сиваш. В качестве экогеографических предикторов рассмотрены две группы ландшафтных данных. К первой группе отнесены цифровая модель рельефа и её производные. Ко второй отнесен комплекс вегетационных индексов, которые полученные на основании снимка со спутника Landsat 8. Экологическая ниша описана с помощью ENFA-процедуры. Для оценки роли масштаба применена процедура граничного размещения точек псевдоотсутствия по отношению к местам присутствия лебедя-шипуна. Экологическая ниша лебедя шипуна может быть описана в терминах ландшафтных экогеографических переменных. Установлено, что свойства экологической ниши лебедя-шипуна зависят от масштаба её рассмотрения. При различных граничных дистанциях мы можем получить совершенно различные, но при этом статистически достоверные, оценки структуры экологической ниши лебедя-шипуна на основе ландшафтных экогеографических предикторов. Роль различных экогеографических предикторов в зависимости от масштаба может сильно изменяться.

The display features of the ecological niche of the Swan-mute swan Cygnus up (Gmelina, 1803) in wintering within the Gulf sivash in geographic and environmental space1Andrûŝenko a. Yu., 2Žukov a. v., 2Kunah o. n.1Melitopol′skij State Pedagogical University named after Bogdan Khmelnitsky2Dnepropetrovskij National University named after Oles GoncharIn the work of assessing the information value of ecogeographical predictors based on remote sensing data from satellites to display features of the ecological niche of the Swan-mute swan Cygnus up (Gmelina, 1803) in wintering within the Gulf sivash. As the two groups examined predictors of ecogeographical landscape data. The first group is assigned digital terrain model and its derivatives. The second set of classified vegetation indices obtained from Landsat 8 snapshot. Ecological niche describes using ENFA-procedure. To assess the role of scale applied edge procedure properties psevdootsutstviâ points towards the places of presence of Swan-mute swan. Ecological niche Swan mute swan can be described in terms of landscape ecogeographical variables. Found that the properties of the ecological niche of the Swan-mute swan depends upon the scale of its consideration. Under various boundary ranges we can get an entirely different, but statistically valid, assess the structure of the ecological niche of the Swan-mute swan based landscape ecogeographical predictors. The role of the various ecogeographical predictors depending on the scale can vary greatly.Keywords: Swan-shipun, ecological niche, ENFA, remote sensing data

in the assessed value of environmental geographic information predictors derived from remote sensing data from satellites, to display features of the ecological niche mute swan Cygnus olor (Gmelin, 1803) in the period of hibernation within Sivash. The two groups of landscape data are considered as predictors of environmental geographic. The first group includes digital elevation model and its derivatives. The second is related complex vegetation indices, which are derived on the basis of satellite images Landsat 8. Ecological niche described by ENFA-procedure. To assess the role of scale to apply the procedure of placement psevdootsutstviya boundary points with respect to the presence of places of mute swan. Ecological niche mute swan can be described in terms of landscape eco-geographical variables. It was found that the properties of the ecological niche of mute swans depend on the scope of its review. At various boundary distances, we can get a completely different, but it is statistically significant, the ecological niche structure evaluation mute swan on the basis of environmental geographic landscape predictors. Role of various eco-geographical predictors depending on the scale can vary greatly.
