Abstract
The article analyzes the possibility of evaluating the current state of forest protection plant in the Stavropol Territory based on remote sensing data. With the help of photogrammetric and kartometric methods, space snapshots are analyzed for the model territory of the Stavropol Territory (Novoaleksandrovsky City District). The use of geo-information technologies allowed us using a cartographic method to estimate the current state of forest belt and determine their qualitative and quantitative characteristics. In the process of digitizing and decrypting, forest belts were divided into categories by destruction. In total, 2524 forest belts with a total area of 10.95 thousand hectares were allocated during the work. As a result, it was possible to assess the qualitative state of the forest belt of the Novoaleksandrovsky urban district and reveal that entire and slightly destroyed protective forest belts are greater than in quantitative terms and in the area they occupy. Further, in the process of the study, the quantitative characteristics of the forest belt were established—the area was determined, and the length and width of all protective forest plantations of the Novoaleksandrovsky urban district was determined and entered into an attribute table. It has been established that the width of most of the protective forest belt (1281 pcs) in the area of the study is from 20 to 30 meters, and 1001 forest belts have a width of more than 30 m. The most common length of forest belt is less than 500 m. (1034 pcs.) and 500–1000 meters (680 pcs.). Square characteristics of protective forest plantations are much more inhomogeneous—so, completely scaffolding was revealed 247 pcs., With a total area of 1058 hectares. Slightly destroyed forest belt 1623 pcs. and their area are 7395 hectares. Significantly destroyed forest belt 41 pcs., with an area of 1734 hectares and fully destroyed—44 pcs., with an area of 213.8 hectares. The proposed research methodology and evaluation of protective forest plantations can be used for other territories of the Stavropol Territory for a more complete study of the state of the region of the region.

ВВЕДЕНИЕ Для всей территории России характерна значительная разбалансированность сельскохозяйственных земель
В процессе оцифровки из района исследования были исключены территории населенных пунктов, а также оцифровке не подвергались те области, где защитные лесополосы между полями отсутствуют
В то же время, достаточно небольшое количество лесополос можно охарактеризовать как «целые», во многих случаях отмечаются локальные разрушения защитных лесонасаждений, которые с течением времени могут привести к их дальнейшей деградации
Summary
ВВЕДЕНИЕ Для всей территории России характерна значительная разбалансированность сельскохозяйственных земель. МАТЕРИАЛЫ И МЕТОДЫ ИССЛЕДОВАНИЯ На территории Ставропольского края лесополосы высаживались в отдельные периоды [60–80] гг. Оценка состояния лесополос проводилась визуально, с использованием данных дистанционного зондирования – снимков, доступных в сервисе Google Maps. Эмпирически нами было установлено, что снимки земель сельскохозяйственного назначения имеют пространственное разрешение около [2,5] м/пиксель, что достаточно для нашего исследования.
