“…In fields with annual mechanical tillage, so-called explerents predominate, characterized by high seed productivity and the ability to quickly occupy free spaces. These are species that form groups at the initial stage of restorative succession [1,2], including field thistle (Cirsium arvense L. Scop.…”

The purpose of the work is to analyze the dynamics of soil fertility indicators under forest belts in comparison with the inter-belt space in the agricultural landscape due to soil transformation under the influence of adaptive landscape farming systems. A comparative analysis of the variability of soil fertility indicators in forest belts and agrocenoses revealed similar trends in its direction and intensity, which indicates the uniform nature of the soil-forming process. However, some features have been identified. The humus content in the soils of forest belts is on average slightly higher than in the space between the belts. This is caused by higher (2 times) rates of humus accumulation in them in the first period after the development of landscape farming systems. It is during this period that the weedy and rhizomatous stages of restorative succession of the herbaceous flora of forest belts are confined, characterized by a powerful vegetative mass of vegetation and, consequently, an equally significant supply of fresh organic matter, rich in nutrients, into the soil.

“…Among all the indices considered, the best indicators of soil erosion, according to our study and sources (Gusev et al 2020), are NDVI and GDVI, determined using the non-parametric Mann-Whitney criterion. The degree of soil erosion in the field was assessed through a morphological description of the profile of the key site (Shcheglov andGorbunova 2011, Huang et al 2021).…”

The aim of the work is to develop a method of landscape dynamics under anthropogenic impact. The developed methodology is tested on the territory of Kostanay region, which is one of the main regions of mining industry development, with a focus on iron ore mining and crop production. Space images and field survey results are used as input materials. In general, the work consists of the following six stages: the first stage includes the selection and processing of space images, the second stage includes the calculation of indices based on data from different channels of space images, the third stage includes field work aimed at collecting information for verification of the obtained results on the basis of RS data, the fourth stage includes the calculation of range values, the fifth stage comprises verification of the obtained indices, and the final sixth stage deals with calculation of the integral index of landscape degradation degree and analysis of landscape dynamics under anthropogenic impacts. The calculation of the integral indicator of the degree of degradation of the natural environment of the Kostanay region, based on the degradation of each indicator in the conditions of anthropogenic impact, allowed for identification of landscapes with different degrees of degradation (from weak to very strong). The research confirmed that landscapes with a high degree of degradation under anthropogenic impact are confined to semi-desert landscapes in the south of the study region. The degradation of these landscapes is associated not only with anthropogenic impacts but also with natural and climatic features that influence the development of landscape pollution processes. On the contrary, landscapes with a weak degree of degradation correspond to the forest-steppe and steppe zones, characterized by a high level of economic development and resistance to anthropogenic impacts. The verification of the obtained indicators by the values of the remaining 25% of field points determines the reliability of the obtained results, ranging from 87% to 92%, confirming the correct choice of methods and techniques for obtaining the results, especially the choice of field methods and vegetation and non-vegetation indices for assessing the selected indicators. Subsequently, based on the verified map of degradation of the natural environment, created through space monitoring for a certain period, it is possible to forecast the functioning of the natural environment in the conditions of anthropogenic impact.

“…Статистический анализ выполняли с помощью программы STATISTICA 6.0. Не менее важен «сукцессионный» аспект воздействия S. canadensis: его вторжение приводит к ингибированию восстановительных сукцессий и к остановке сукцессионного процесса на нелесной стадии [3,4]. Временным «окном», через которое S. canadensis проникает в сукцессию, являются бурьянистая и луговая стадии.…”

“…Все перечисленные классы представляют собой флористически разнообразные, но сукцессионно однородные сообщества, соответствующие бурьянистой или луговой стадии, которые в условиях Беларуси относительно быстро сменяются лесной стадией по мере развития деревьев и кустарников [4]. Соответственно, при разрастании S. canadensis через несколько лет образуются его монодоминантные травостои, которые, как указывалось выше, препятствуют естественному возобновлению деревьев и кустарников [2,3]. В результате сукцессия не Литература…”

Для оценки влияния инвазии Solidago canadensis L. на биоразнообразие в условиях ландшафтов Беларуси выполнено сравнение результатов двух серий геоботанических съемок 2005–2006 и 2015–2017 гг. на 7 ключевых участках. На всех участках проективное покрытие S. canadensis возросло с 0–8 до 25–94%. При этом снижалось видовое разнообразие (число видов растений, видовое богатство) и ценотическое разнообразие (число синтаксонов растительности), формировался гомогенный растительный покров из сообществ S. canadensis; замедлились сукцессионные смены растительности. Установлена корреляция между проективным покрытием S. canadensis и видовым богатством (коэффициент корреляции Спирмена 0,64 при p менее 0,0001).
