Purpose: The main purpose of the research is to define the group of radiation risk (GRR) on the incidence of hypertension among Russian recovery operation workers of the Chernobyl accident (liquidators). Material and methods: The object of research is the cohort of the Russian liquidators with the known individual doses of external gamma exposure of all body. Definition of GRR on incidence of hypertension is based on assessment of excess relative radiation risk (ERR) and relative radiation risk (RR) in the observed cohort of 106 thousand liquidators, having average accumulated dose of external gamma exposure of all body of 0.11 Gy and the maximum individual doses about 1 Gy. Results: From 1986 to 2012 in this cohort 57112 cases of hypertension have been diagnosed, basically – essential (primary) hypertension (39.2 %) and hypertensive heart disease (53.8 %). The statistically significant ERR of incidence of hypertension was observed only for liquidators who entered the Chernobyl zone of recovery operations within the first year after the accident (before 26.04.1987): ERR/Gy = 0.26 with 95 % CI (0.12; 0.41), p < 0.001. For other liquidators no significant associations between the explosion dose and the incidence of hypertension were revealed. For nonparametric estimates of RR in dose groups (relative to the control group with doses < 0.05 Gy) the statistically significant radiation risk was observed only for the dose group over 0,25 Gy: RR = 1.07 at 95 % of CI (1.02; 1.12), p = 0.023. GRR on incidence of hypertension equal to 4 % of the number of the studied cohort of liquidators: 4515 persons with accumulated doses of 0.25 Gy and higher, arrived to the Chernobyl area within the first year after the accident. In GRR 2597 cases of diseases of hypertension were diagnosed; statistically significant (p = 0.023) assessment of RR is equal 1.07, with 95 % a confidential interval (1.02; 1.12) and an average dose 0.297 Gy. During observation from 1986 to 2012 6.5 % of cases of diseases of hypertension (170 cases) in GRR can be related to radiation-caused ones. GRR for the beginning of 2013 consisted of 2919 persons 1909 of whom had already had diagnoses of hypertension (125 – radiation caused). Since 2013 for lifetime in GRR from 43 to 66 cases of diseases of hypertension which can be related to radiation-caused are expected. Conclusion: As hypertension is the risk factor for many circulatory diseases, address prevention and treatment of hypertension in GRR in the first years after radiation accidents could reduce the radiation-caused loss healthy years of participants of elimination of such accidents.

.One of the most urgent and significant social problems of our time is the problem of maintaining the ecological stability. Important role in optimizing the environment play greenery. Being a biological filter, they perform environmental, environment protection, recreational and social functions. Qualitatively improving the environment, urban plantations experience the negative impact of certain environmental factors and therefore require careful treatment and proper protection. The results of a comprehensive evaluation of the forest park plantations located in the northern district of the city district of Voronezh. Study included determination of the species composition of plants, forming phytocoenosis, assessment of health status and forest pathology plantations, and the analysis of the spatial structure of the stand, the class definition of aesthetic and hygienic value of the site. Range of plants at the site of research is represented by 3 divisions, 4 classes, 21 orders, 24 families, 38 genera and 44 species. Distribution of plants according to life forms is as follows: tree - 12 species, shrubs - 8 species, vines - 2 species, herbaceous plants - 22 species, lichens - 1 species. On the territory of the forest park very valuable plants are revealed, which include Scots pine, quickbeam and Sorbus intermedia, silver birch, Norway maple. The territory of the forest park belongs to the closed type of spatial structure. The stand is formed by cultures of Scots pine at the age of 45 years. Plantation is characterized by impaired stability; plants have signs of disease, pests, abiotic and anthropogenic factors. Hygienic assessment of planting complies with Class 2, the aesthetic value of the object - average one. In order to preserve the forest park plantings and increase their resilience to environmental factors it is proposed to develop the project of reconstruction of the object, including the division of the forest park into functional zones, sanitary measures and for landscaping. Preservation of the park area is a prerequisite for comfortable living of population of Kominternovsky district of city district of Voronezh.

Фурменкова 1 1 -ФГБОУ ВО «Воронежский государственный лесотехнический университет имени Г. Ф. Морозова», г. Воронеж, Российская ФедерацияНа основе полиструктурного подхода рассмотрены и классифицированы биоциркуляционные ландшафтные структуры Воронежского биосферного заповедника. Определена приуроченность родов экосистем к ландшафтным уровням. Полученны результаты по характеристике экологических систем, их распределения и свойств. Предагаемый подход позволил выделить на территории Воронежского заповедника тип транзитных, автономных и аккумулятивных наземные экосистемы, относящихся к семействам быстро текущих рек и ручьев, пойменных лесов и высокотравий, светлохвойных лесов, луговых степей, летнезеленых лиственных лесов(дубовых), летнезеленых лиственных лесов (мелколиственных), болот. Экосистемы автономного типа функционируют на основе экономного, а в ряде случаев и повторного использования необходимых для жизнедеятельности веществ. Абиотический перенос веществ в экосистемах автономного типа непостоянен. Накопление веществ в пределах экосистем несколько выше, чем в транзитных, но очень сильно уступает аналогичному показателю в аккумулятивных системах. Интенсивность абиотической циркуляции веществ в пределах экосистемы максимальна среди всех типов. Экосистемы транзитного типа функционируютна основе эффективного транзита и удерживания вещества. Обычно компоненты биоты экосистем транзитного типа не отличаются высокой адаптивностью к поиску веществ. Наиболее разнообразны водные транзитные экосистемы, но существуют и различные классы наземных. Экосистемы аккумулятивного типаприспособлены к избытку одних веществ и недостатку других. Экосистемы аккумулятивного типа отличаются максимальным объемом поступающих в экосистему веществ и почти полным отсутствием их выноса. По сравнению с поступлением веществ извне, интенсивность биотической циркуляции веществ внутри экосистемы очень невелика. Накопление же веществ внутри экосистемы в этом типе максимально. Биота аккумулятивных наземных экосистем отличается способностью существовать в условиях недостатка одних веществ и явного избытка других. Принадлежность экосистемы к тому или иному типу определяется особенностями исторического саморазвития биоты.Ключевые слова: полиструктурный подход, геостационарная ландшафтная структура, биоциркуляционная ландшафтная структура, типы экосистем, роды экосистем, ландшафтный уровень.

The article is devoted to the definition of forest pathology condition of plantations of biology (for-est) nature monument "Old-growth areas of upland oak forests", located in the quarter 52 of Pravobe-rezhnoe forestry of Prigorodny district forest, Voronezh region. Definition of certain classes of biological sustainability of forests and evaluation of its sanitary condition during the examination of trees on test plots is carried out. The factors reducing the stability of oak trees are indentified and analyzed. Forest pa-thology plants condition were evaluated for three classes of biological sustainability. Sanitary condition of plantations is evaluated.
