Abstract
It is known that field-protective afforestation is carried out on agricultural lands for protection from abiotic and biotic factors such as dry winds, droughts, soil erosion, and also anthropogenic ones. To study spatial structure of the field-protective belts, test areas were laid in accordance with OST 56-69-83, where the following species were studied: species composition of woody-shrubby and grassy vegetation, continuous enumeration of forest stands. Based on the results of the enumeration taxation, composition of shelter belt, diameter and average height, and state of the stand according to Kraft were determined. There were no archival data on the landing time and the age of investigated forest belts. Field protection zone in the vicinity of Zolotarevka village is represented by the stand of the second generation of both seed and vegetative origin. It is located in Stanichno-Lugansky district of Lugansk region (Ukraine), in the vicinity of Zolotarevka village. Geographical coordinates of the location of the village are 48.90417º N, 39.79361º E. The main tree species (edificator) is represented by European white birch (Betula pendula Roth), planted in rows – 5 rows. The belt is not homogeneous in tree species, although initially it was created only from birch plants. In the first third of the forest belt in one vertical tier the birch is alternating with Norway maple, and then in the middle part there is European white birch. The main tree species in the second forest belt is the acicular plaque (Acer platanoides L.). At the point of contact of plants of indicated cenoses, despite the presence of a break in the work of engineering, there is mixing of these species in the first shelter belt, that is,Norway maple cut out other species of the indicated cenosis, including birch. Having studied the spatial structure and species diversity of plants of all life forms of field shelter belts (Zolotarevka village (Stanichno-Luhansky district of Lugansk region) one can conclude that it is necessary to consider these ecosystems in a sozological aspect.

Summary
ПРОСТРАНСТВЕННАЯ СТРУКТУРА ПОЛЕЗАЩИТНОЙ ПОЛОСЫ В АГРОЦЕНОЗАХ ЛУГАНСКОЙ ОБЛАСТИ кандидат биологических наук, доцент О. ГОУ ВПО ЛНР «Луганский национальный университет имени Тараса Шевченко», г. Для исследования пространственной структуры полезащитной полосы были заложены пробные площади в соответствии с ОСТ 56-69-83, на которых изучали: видовой состав древесно-кустарниковой и травянистой растительности, сплошную перечислительную таксацию древостоя. Таксации определяли состав полезащитной полосы, диаметр и среднюю высоту, состояние древостоя по Крафту. Она расположена в Станично-Луганском районе Луганской области (Украина), в окрестностях с. Полоса неоднородна по древесной породе, хотя изначально она создавалась только из березы повислой. В точке контакта растений указанных ценозов, несмотря на наличие разрыва для работ техники, наблюдается смешение этих пород в первой полезащитной полосе, т. Золотарёвка (Станично-Луганский район Луганской области), можно сделать вывод о необходимости рассмотрения данных экосистем в созологическом аспекте
